NSK Technology for Machine Tools

High-Speed Integrated Motor Spindles B1 Series

Energy-efficient, quiet performance achieved with grease lubrication. >> CAT. No.E2204
The world’s highest-level, high-performance integrated motor spindle.

Outstanding in speed, cutting capability and reliability, and at the top level in the
world, the B1 Series was specifically developed for #40 machining centers.
B1 Series uses Robust Series precision bearings (ceramic ball specification).

1. Low noise, less environmental burden, maintenance-free operation

With a newly developed grease-replenishing lubrication method, B1 Series is quiet,
exerts less impact on the environment and offers 20 000 hours of maintenance-free
performance.

2. High rigidity

Combination of a highly heat-resistant precision bearing—the epitome of NSK’s
expertise—with a FANUC motor providing a wide range of cutting performance.

3. All-in-one unit

Tool specification complies with BT and HSK. The unclamp mechanism is durable
enough to withstand 2 million rotations. Through-coolant capability (7 Mpa) is available
as an option.

Ball Screw Support Bearings TAC Series

High-rigidity, long-life angular contact thrust ball bearings developed >> CAT. No.E1254
specifically for machine tools.
Support unit for high-load machine tools
TAC Series bearings are widely used worldwide as a result of their high rigidity, A support unit comprising several TAC Series
long life and ease-of-use. TAC Series features all the functions required of a ball units is also available as a standard product.
screw support bearing. (Bearing inner diameter: φ17 to φ40)

1. High rigidity

High rigidity achieved by setting contact angle at 60° and using a larger number of
small-diameter balls.

2. Long life

Long operating life is achieved by using durable EP Steel as standard material.

3. Ease-of-use

Bearings for universal combination are available for any type of combination to meet load
conditions.
