Miniature Linear Guide Series incorporate the design of two rows of ball recirculation, the ball track has gothic profile design with 45-degree contact angle to attain the effect of equal load capacity in all directions. Under the restriction of limited space, larger steel balls are used to enhance the load and torque capacity.

Drawn cup needle bearings are designed to support radial loads and reduce friction between rotating components. The low cross section of the drawn cup bearing provides maximum load-carrying capability with a minimum of space required. Drawn cup bearings are easily installed with a press fit in the housing. We offer a wide size range of standard inch and metric drawn cup bearings. There are two basic designs: the full complement and the caged version. Both have a drawn outer shell, which serves as a raceway for the rollers contained in the bearing. The full complement version has the maximum number of rollers mechanically retained by the drawn outer shell. This design combines high radial load-carrying capability with low cost. The standard caged version contains a one-piece steel cage to guide and retain the rollers. This design provides high speed and maximum lubricant retention capability.

Linear motion ball bearings are used widely in the defense, precision machinery, medical instrument, chemical, printing, agriculture, robotic, automatic production line etc. fields. Linear motion bearings are mainly used in Vertically, Horizontally movement but also can be rotate.

Ball screw assemblies consist of a screw with a precision ground or rolled helical groove, a nut (the outer race) with an internal groove, and a circuit of precision steel balls that recirculate in the grooves between the screw and nut. This anti-friction design converts torque to thrust as either the screw or nut turns and the other component moves in a linear direction.

Deep groove ball bearings are very widely used. A deep groove is formed on each inner and outer ring of the bearing enabling them to sustain radial and axial loads in either direction as well as well as the complex loads, which result from the combination of these forces. Deep groove ball bearings are suitable for high-speed applications. In addition to unsealed bearings, deep groove ball bearings include ball bearings with greased sealed inside (sealed or shielded) and bearings with a snap ring that simplify structure around the bearing and design.

One-way bearings are widely used in mining /hydraulic / textile / printing / washing machines, conveyor systems and so on. One-way clutch bearings allow shafts to be driven in only one direction; it allows one shaft to "freewheel" if it is spinning in the opposite direction from the direction at which the clutch is designed to engage.   The one-way clutch bearing is designed very much like the roller bearing, but the rollers are allowed to move up small ramps. When the shaft turns in direction that locks the clutch, the rollers roll up small ramps and wedge into cavities. When this happens, the clutch locks and the shaft will drive the gear, or the gear will drive the shaft. These bearings are used extensively in automatic and manual transmissions allowing gears to be engaged depending on their direction of rotation.

These bearings are designed primarily to support axial loads at contact angles between 30 and 90. Just as with radial bearings, these bearings differ according to the type of rolling element they use: there are thrust ball bearings that use balls and thrust roller bearings that use rollers. Single direction thrust ball bearingsSpherical roller thrust bearingsCam Followers Roller FollowersCam FollowersCam Followers are bearings with a stud incorporating needle rollers in a thick walled outer ring. They are designed for outer ring rotation and both crowned and cylindrical outer rings are available.

The Miniature and Extra Small Bearings are widely used in application for smaller dimensions and lesser load capacity.

• Open type
• Shielded type
• Shielded type with snap ring

These bearings can be classified as follows:

• Angular contact ball bearing
• Four-point contact ball Bearing
• Double row angular contact ball bearing

Angular contact ball bearings are non-separable bearings which have a certain contact angle in the radial direction relative to the straight line that runs through the point where each ball makes contact with the inner and outer rings.

Four-point angular contact ball bearings have a contact angle of 30 and inner rings which are separated in half. These bearings are capable of accommodating radial loads, axial loads in either direction, and have a high capacity for momentary loads as well.

The structure of double row angular contact ball bearings is designed by arranging two single row angular contact bearings back-to-back in duplex (DB) to form one united bearing with a contact angle of 25.

The outer ring raceway of self-aligning ball bearings forms a spherical surface whose center is common to the bearing center. The inner ring of the bearing has two raceways.

The balls, cage, and inner ring of these bearings are capable of a shifting in order to compensate for a certain degree of misalignment with the outer rings. As a result, the bearing is able to align itself and compensate for shaft / housing finishing unevenness, bearing fitting error, and other sources of misalignment.

Tapered roller bearings consist of four interdependent components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer. The taper angles allow the bearing to handle a combination of radial and thrust loads. The steeper the cup angle, the greater the ability of the bearing to handle thrust loads.

Spherical roller bearings consist of an outer ring having a continuous spherical raceway within which operates two rows of barrel-shaped rollers, which are in turn guided by an inner ring with two raceways separated by a center rib. This bearing has self-aligning properties, and therefore is suited for use where misalignment between the inner and outer rings occurs from housing installation error or shaft flexure.

Drawn Cup Needle Bearing

Drawn cup needle bearings are designed to support radial loads and reduce friction between rotating components. The low cross section of the drawn cup bearing provides maximum load-carrying capability with a minimum of space required. Drawn cup bearings are easily installed with a press fit in the housing. We offer a wide size range of standard inch and metric drawn cup bearings.

There are two basic designs: the full complement and the caged version. Both have a drawn outer shell, which serves as a raceway for the rollers contained in the bearing. The full complement version has the maximum number of rollers mechanically retained by the drawn outer shell. This design combines high radial load-carrying capability with low cost. The standard caged version contains a one-piece steel cage to guide and retain the rollers. This design provides high speed and maximum lubricant retention capability.

Heavy-duty needle roller bearings consist of a machined and ground channel-shaped outer ring with a complement of needle rollers retained and guided by a cage. The thick outer ring provides maximum load capacity and shock resistance with a relatively small radial cross section.

With the high-strength cage retaining and guiding the rollers, this design provides high speed and lubrication retention capability. A lubrication groove and hole in the O.D. facilitate relubrication through the outer ring. These bearings can be used with or without a machined and ground inner ring depending on the suitability of the shaft as a raceway surface

Needle Thrust Bearings are bearings in which the radically arranged rolling elements are accurately guided by the cage. It is very right bearing which has the capacity to bear large loads in a small space. These bearings have various washers so can be chosen for every kind of application.

If the mounting surface for the bearing in the machine has been hardened and ground, and is of a high precision, it is possible to use only the cage assembly by itself, making it even more compact and able to withstand high speed and fluctuating heavy load. They are suited to use when high accuracy is required, such as in automobile driving mechanisms, machine tools, NC machinery, high-pressure pumps, etc.

Deep groove ball bearings are very widely used. A deep groove is formed on each inner and outer ring of the bearing enabling them to sustain radial and axial loads in either direction as well as well as the complex loads, which result from the combination of these forces. Deep groove ball bearings are suitable for high-speed applications.

In addition to unsealed bearings, deep groove ball bearings include ball bearings with greased sealed inside (sealed or shielded) and bearings with a snap ring that simplify structure around the bearing and design.

Pillow Block units are a combination of a bearings and a housing of high-grade cast iron or pressed steel, which come in various shapes. The bearing unit consists of high-grade grease, which runs for lo nger period. Pillow blocks are basically used in environments where dust and rain are inevitable, and for heavy industrial machinery such as construction and transportation equipment. They are also used in flourmills, steel mills, foundries, galvanizing plants, chemical plants etc.
