NU2215E, a products in GQZ, belongs to a type of cylindrical roller bearing.

This nu2215e cylindrical roller bearing with a polyamide cage and removable inner ring is suitable for applications that support high radial loads. This roller bearing has a CN (normal) radial clearance for applications and operating conditions with normal shaft and housing tolerances where thermal expansion is not a factor. This is a single row roller bearing that supports high radial loads with low friction. A removable inner ring in the open bearing allows application of lubrication. This roller bearing is measured in metric units for industry cross-matching and parts consistency.

Cylindrical roller bearings are used in applications where high radial loads are present such as in conveyer belts, traction motors, railway car axle boxes, and oilfield mud pumps, among others. Please contact GQZ for any questions!
