TAC Series Spindle Bearings

TAC series bearings are thrust angular contact ball bearings for NSK ball screw support. TAC series bearings include: open bearing series and sealed bearing series.

Features for TAC series spindle bearings:

1. High performance design spindle bearings

High rigidity: Big quantity of steel balls, 600 contact angle, high rigidity.
Long life: With EP steel, therefore, bearing life is 3 times that of ordinary bearing steel SUJ2.

2. Contact sealed bearing series: high reliability, high dust resistance performance

The sealed bearing has good dust resistance and the grease is not easy to leak.
In addition, with light contact seal ring, bearing torque is low with low heat generation.

3. Easy to install spindle bearings

Open bearings: Installation time is shortened
Sealed bearings: filled with grease, and the sealing rings on back and front are of different colors, which is easy to identify the direction.
