Description
Track rollers with spherical profile - CR28-2Z  C30Z  C30R CR28R CR28.2RS CX30R CR28SS.2RS  C30S01 C30S02
Track roller series CR28...  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

C30S01: with high-temperature grease, it can work 300 degrees Celsius.
