Product Description

The Linear Ball Bearing (LBB) Ultra-Precision gage heads are dimensional gaging probes engineered for highly precise and repeatable measurements in quality control and metrology applications. The linear ball bearing system within the gaging probe reduces radial play to a minute level and minimizes friction for ultra-precise measurement.
The bearing assembly utilizes two circumferential rows of miniature balls. The balls ride on a non-rotating plunger. The plunger is hardened to Rockwell 65, hard-chrome plated and precision ground for optimal repeatability and resistance to brinelling. The contact end of the plunger has a removable tungsten carbide ball tip. Plunger and bearings are enclosed in a cylindrical housing, hand-honed and fit to the ball bearing assembly. Precision fitting provides for exceptional repeatability. With the bearings and housing matched in hardness, the plungers can better tolerate side loads for a longer life cycle.
