They can be combined freely according to the actual applications, as there is small clearance, high precision, stable running, light weight, small inertia, compact size, so it is suitable for all kinds of high repeat precision, fast response, small mechanical structure, precision measuring instruments. Such as D/A conversion mechanism, and a number of solenoid valve.

Product Comparison:

The traditional has the relative motion of the hole and the shaft is clearance fit, the movement between hole and shaft friction coefficient is larger, the motion of the shaft in the process of movement with trace, requiring high precision in some not too. Using Miniature Ball Bearing Guide Bushings, shaft and the trace of the interference ball contacts, and movement precision, rolling friction instead of sliding friction, rolling flexible, small friction coefficient, long service life.
 
Precision Level:
Equipped with G10 level ball in set of standard steel ball (diameter changes the amount of 0.0025 mm), which can realize the interference fit.
Adopt unique steel ball lock technology, ensure every steel ball freely and not fall off.

Service Life:
Shaft and outer steel bushing adopt high quality bearing steel material, after heat treatment and mirror finishing grinding processing. The steel ball arrangement is compact, reasonable design, enables it can be work long time.

Installation Instructions:
Recommendations steel sleeve hole for H6 / H7, fixed by using suitable adhesive.
When press -fit, to check the amount contraction of the inner hole, adjusting the diameter of shaft to correct preloading, preloading is generally  less than - 0.002 mm.
