Screw drive bearing arrangements are subjected to requirements that often cannot be optimally fulfilled by the design construction of conventional bearings.
For the design of bearing arrangements for the highly dynamic operating conditions in screw drives that have high accuracy, high load carrying capacity, high rigidity, low friction, are easy to fit and maintenance-free or low-maintenance, there is a wide range of INA and FAG axial angular contact ball bearings. With this product range, solutions can be found to all the technical and economic demands placed on the bearing arrangements of screw drives.

Single row and multi-row design:
Axial angular contact ball bearings are available as single, double or triple row ready-to-fit units. They are self-retaining and comprise thick-walled, geometrically stable outer rings, ball and cage assemblies and one-piece or two-piece inner rings. In several series, the outer ring has through holes for simple flange mounting to the adjacent construction.
The bearing rings are matched to each other such that a defined preload is achieved when the rings are clamped in place using a precision locknut.

Radial and axial carrying capacity:
Due to the contact angle of 60°, the bearings can support not only radial forces but high axial forces as well.

Bearings 7602, 7603 and BSB are designed as universal bearings,They can be combined in a wide range of sets for different requirements.

The screw bearing is the ideal product for turning the rotary motion into a straight motion, or turning the straight motion into a rotary motion. Ball screw bearing's function is to convert rotary motion to linear motion, or convert torque into axial force repeatedly, at the same time combines the characteristics of high accuracy, reversibility and high efficiency. Precision ball screw support use angular contact ball bearing, apply special design according to different purposes, divided into two categories, high rigidity and high load series products, suitable for high precision feed.

High precision: ball screw support bearing precision is mainly P4 class.
High rigidity: the contact Angle of ball screw bearings is 60 degrees, which greatly increases the axial force of the bearing.
Good self-lubrication: with seals and add grease ball screw bearing has the self-lubricating, free maintenance, dustproof, waterproof good qualities, such as improve bearing service life greatly.
