Linear rail bearing, linear motion roller Other code:CR18-2Z CR20Z CR20R CRX20R use to compact linear rail, for T rail, U rail, K rail. Concentric or eccentric pin can be added for easier installation.
Track rollers with spherical profile - CR18-2Z CR20Z CR20R CRX20R Track roller series CR20... are precision ball bearings that they are generally used in precision linear motion guide. They are supplied with rubber seals and metal shields respectively, and are also available with concentric pivots and eccentric pivots.
Material: Bearings: High quality chromium steel or martensitic stainless steel. e.g. 100Cr6 SUS440C Pivot: High quality carbon steel or stainless steel. e.g. 1045 SUS304
