Match#: 6215Z, 6215-2Z, 215SS, 6215ZZ, 6215-2ZJ1, 215KSFF, 215KDD, 77215, 6215.2ZR
The 6215-2Z is a 75mm single row radial ball bearing that’s metal shielded on both sides and pre-lubricated with grease. It’s a 130mm OD sealed ball bearing 6215ZZ made of chrome steel and features deep groove geometry that’s perfect for high speeds and heavy radial and axial loads. Rolling bearings like 6215.2ZR use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed and Shielded bearings are lubricated with oil or grease in the bearing factory, while open bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the 6215-ZZ bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan.
