This open miniature deep groove ball bearing of size 636 (6 mm bore / 22 mm outer diameter / 7 mm width) features a PEEK cage/holder and AISI 304 stainless steel balls, with no seals or shields. This makes it suitable for applications requiring minimal interference and low friction.
The open design allows direct lubrication and visual inspection. With the PEEK components, the bearing offers enhanced chemical and temperature resistance, and the stainless steel balls provide corrosion resistance.
Typical applications include corrosive environments, lightweight drive systems, industrial and medical technology.
