Product Description
The 639-2Z is a deep groove ball bearing with 45mm inner diameter, 100mm outer diameter, and 25mm 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 mining machinery, heavy vehicles, and industrial compressors.
