Product Description
The 638-2Z is a deep groove ball bearing with 40mm inner diameter, 90mm outer diameter, and 23mm thickness, featuring double-sided metal shields (2Z) for non-contact dust protection. Constructed from GCr15 steel with a pressed steel cage, it is ideal for ultra-heavy-load, high-dust applications like heavy machinery, mining equipment, and industrial compressors.
