Item No: 608 series bearing
Miniature ball bearing
Miniature ball bearing is composed of an outer ring, inner ring, a set of ball and a cage. Structure is simple and easy maintenance. Mainly used to bear radial load, but also bear certain axial load, when the axial clearance increased, will have the performance of angular contact ball bearings and can bear large axial load, this kind of bearing low friction coefficient, high limiting speed, size range and diverse.

 

Detailed Description
1) Model: Open, Z, ZZ, RZ, 2RZ, RS, 2RS
2) Quality level: reach the same level as the Japanese and European bearings
3) Tolerance level: ABEC-1 (P0), ABEC-3 (P6), ABEC-5(P5)
4) Vibration standard: V1, V2, V3

5) Noise standard: Z1, Z2, Z3, and Z4

Explanation:
　　Z represents that one-side of the deep groove ball bearing is mental dust cover, and ZZ represents that both sides are mental dust cover.
　　RS represents that one-side of the deep groove ball bearing is non-touch grommet, and 　　2RS represents that both sides are non-touch grommet.
　　RZ represents that one-side of the deep groove ball bearing is contact grommet, and 2RS represents that both sides are contact grommet.
