NTN Bearing

PILLOBALLS

IKO PILLOBALLs are compact self-aligning spherical bushings which can support a large radial load and a bi-directional axial load at the same time. These bearings are available in insert type, die-cast type and lubrication-free type depending on the type of sliding surface. In the insert type, a spherical inner ring makes contact with a special copper alloy bushing with superior run-in properties. In the die-cast type, a spherical inner ring makes direct contact with the bore surface of the body of special zinc die-cast alloy. In the maintenance-free type, a spherical inner ring makes contact with a special self-lubricating PTFE liner. Thus, a smooth rotational and oscillatory motion can be achieved with superior anti-wear and load properties in each type. PILLOBALL Rod Ends have either a female thread in the body or a male thread on the body, so they can be easily assembled onto machines. They are used in control and link mechanisms in machine tools, textile machines, packaging machines, etc. The maintenance-free type is especially suitable for loading in one direction and is the best choice for machines in which oil must be avoided such as food processing machines, or machines which cannot be re-lubricated.

Spherical Bushings

IKO Spherical Bushings are compact self-aligning spherical bushings with inner and outer rings in contact with the sphere, which can support a large radial load and a bi-directional axial load at the same time. There are many models of Spherical Bushings, but they are basically divided into steel-on-steel types and maintenance-free types according to the kind of sliding surfaces. Steel-on-steel Spherical Bushings have inner and outer rings of high-carbon chromium bearing steel, of which sliding surfaces are phosphate-treated and then dry-coated with molybdenum disulfide (MoS2). They can, therefore, operate with low torque, and have excellent wear resistance and large load capacity. They are especially suitable for applications where there are alternate loads and shock loads. They have wide applications mainly in industrial and construction machinery. Maintenance-free Spherical Bushings consist of an outer ring which has a special PTFE liner reinforced with copper alloy meshes on the sliding surface, and a spherical inner ring of which sliding surface has a hard chromium plating. Creep deformation due to compressive load is small, and wear resistance is superior. Thus, they are maintenance-free and can be used for extended periods of time without re-lubrication. They are especially suitable in cases where fixed directional loads are applied and are used mainly in food processing machines and construction machinery and in other applications in which the use of oil is undesirable or lubrication is not possible.

Slim Type Crossed Roller Bearings

Slim Type Crossed Roller Bearings are slim bearings having a small outside diameter against the bore diameter and a narrow width. In addition, types with cage, types with separator, and full complement types are available, which can be selected according to the intended use.

Mounting Holed Type High Rigidity Crossed Roller Bearing V

The Mounting Holed Type High Rigidity Crossed Roller Bearing has an integral structure (non-split) for both the inner and outer rings, with mounting holes that allows it to be easily attached to equipment. Further it is less subject to peripheral structures such as housing or pressure plate and realizes high rigidity and high-accuracy guidance.

Non-Separable Roller Followers

These non-separable type bearings have side plates press-fitted on both sides of the inner ring. Types include caged and full complement, as well as shield and sealed types. These bearings are also available in a high corrosion-resistant stainless steel specification, suitable for applications where rust prevention oil cannot be used, such as in cleanroom environments. Inch series non-separable roller followers are full complement type bearings with a black oxide surface treatment.

Cylindrical Roller Followers

These bearings are full complement type bearings incorporating double rows of full complement cylindrical rollers in the outer ring. They can withstand large radial loads. Additionally, the outer ring is guided by the outer ring shoulder and the end face of the cylindrical rollers to the axial direction.

High Rigidity Type Crossed Roller Bearing V

High Rigidity Type Crossed Roller Bearing V has a solid one-piece construction for both inner and outer rings. Therefore, high accuracy and high rigidity are achieved, and mounting errors can be minimized. As separators are incorporated between the cylindrical rollers for smooth rotation, these bearings are suitable for applications where rotation speed is comparatively high. These bearings are widely used in the rotating parts of industrial robots, machine tools, medical equipment, etc., which require compactness, high rigidity and high rotational accuracy. In addition, bearings made of stainless steel and those with inner and outer rings provided with mounting holes are also available on request. Please contact IKO.

C-Lube Roller Followers

These Roller Followers are lubricated with C-Lube, a thermosetting solid-type lubricant which fills the inner space of the bearing. C-Lube is lubricant made of a lot of lubrication oil and fine particles of super-high molecular polyolefin that are solidified by heat treatment. As the bearing rotates, the lubricating oil oozes out onto the raceway surface in proper quantities, maintaining the lubrication performance for a long period of time.

Super Flexible Nozzles

The IKO Super Flexible Nozzle is a compact nozzle used on machine tools to supply and spray cutting oil exactly at a specified location. Since the angle of the nozzle can be easily changed, the oil supply can be concentrated on the working area, and cooling and lubrication can be performed effectively. As a result, cutting resistance is reduced and superior finish is obtained, achieving high machining accuracy. The tool life can also be extended, which can result in cost savings. The Super Flexible Nozzle can be used at the spindle end of machining centers and at the tool holder of an NC lathe.

Easy Mounting Type Cam Followers

These bearings have a stepped tapered portion on the stud, making mounting easy by fixing a set screw to the stepped portion: thus they are optimal for applications such as pallet change.

C-Lube Cam Followers

These Cam Followers are lubricated with C-Lube, a thermosetting solid-type lubricant which fills the inner space of the bearing. C-Lube lubricant is made from lubrication oil and fine particles of super-high molecular polyolefin that are solidified by heating. As the bearing rotates, the lubricant oozes out onto the raceway surface in proper quantities, maintaining the lubrication performance for a long period of time.

L-Balls

IKO L-Balls are self-aligning Spherical Bushings consisting of a special zinc die-cast alloy body and a studded ball which has its axis at right angles to the body. They can perform tilting movement, oscillating movement and rotation with low torque, and transmit power smoothly due to uniform clearance between the sliding surfaces. Their superior wear resistance assures stable accuracy for long periods of time, and maintenance is simple. They are very economical bearings. For these reasons, they are widely used in link mechanisms in automobiles, construction machinery, farm and packaging machines, etc.

Separable Roller Followers

Separable Roller Followers are assembled by combining an outer ring, inner ring and needle roller cage. They can be separated from one another, so handling is easy. Oil lubrication is also easy, making them suitable for high-speed rotations. Two types are available: without inner ring RNAST and with inner ring NAST. The inner ring type includes open, shield, and sealed types.

Block Type Linear Ball Spline

The IKO Block Type Linear Ball Spline is a linear motion rolling guide in which the slide unit performs endless linear motion along the spline shaft.

The structure enables the rollers to be guided accurately without creating skew, yielding extremely stable and smooth linear motion.

Flat Roller Cage

The IKO Flat Roller Cage is a limited linear motion guide consisting of high accuracy rollers and very precise cages with low cross sectional height. Since rollers are assembled in a cage with a small pitch distance, load ratings are large and rigidity is high. A single row model and a double row model with a 90 angle are standard and can be used to convert conventional plain guiding parts in machine tools into a rolling guide type, without a large-scale redesign of the bed. Since the high accuracy cage guides the rollers, the frictional resistance is very low without stick-slip, and stable linear motion is obtained.Cages made of synthetic resin are ideal for applications where low noise is required. The rollers are caged securely in a retainer, allowing for easy handling.

Thrust Bearing

IKO Thrust Bearings consist of precisely machined cages and rollers. They have high rigidity and high load capacity and can be used in small spaces. Thrust Needle Roller Bearings use needle rollers, while Thrust Roller Bearings use cylindrical rollers. Various types of raceway rings are available, and can be selected according to the operating conditions. When the bearing mounting surface of a machine is heat-treated and finished by grinding, Thrust Bearings can be used without raceway rings, making the machine more compact. They are best suited for applications where high accuracy is required at high speeds and under fluctuating heavy loads, such as the drive mechanisms for automobiles, machine tools, and high-pressure pumps.

Combined Type Needle Roller Bearings

IKO Combined Type Needle Roller Bearings are combinations of a radial bearing and a thrust bearing.
