40TAB07U 40TAC72 Nachi Ball Screw Bearing

40TAB07U 40TAC72 Nachi Ball Screw Bearing

These 40TAB07U 40TAC72 Nachi ball screw bearings have been improved to exceed industrial demands for high precision and high speed requirements. The TAB type support precision actuators in a wide range of applications such as machine tools, precision measuring equipment and robot technologies.

Some features of the 40TAB07U 40TAC72 Nachi ball screw bearings: 

High Axial Rigidity

Greater number of balls with polyamide cage achieves significantly increase rigidity compared with conventional angular contact ball bearings.

Simple and Compact

The 60 degree contact angles allow the bearing to simultaneously carry the thrust load and certain amount of radial load. This characteristic allows you to have a simple and compact design.

High Capacity and Low Noise
The use of large balls in higher bearing capacity beyond what Nachi adopted with the polyamide cage combined with the high performance, quiet operating, great to achieve low noise.

Energy Saving

Superior seal designs offer low starting and running torque; minimising power loss.

Easy Assembly

Initial ball screw bearing preloading provides for ease of assembly by eliminating complex assembly adjustment.

Proper Seal Type

Seal types include contact type, excelling in sealing, and non-contact type for decreasing torque loss and temperature rise.

Pre Pack Grease

Bearings are prepacked with high performance grease eliminating the need for additional grease packing during assembly.

Compatible Dimensions with Current Bearings

Boundary dimensions are compatible with current open bearing enabling interchangeability with existing applications.

Universal Ground Set Combinations (Flush Ground) for 40TAB07U 40TAC72

These bearings with the suffix "U" are universal ground and that permits them to use random combinations where two or more bearings are mounted.
