N300 Series

N300 series cylindrical roller bearings provided by Peple Parts had a diameter of 40mm-150mm, outside diameter of 100mm-320mm, width of 23mm-65mm. In addition, we provide two types of lubricants for cylindrical roller bearings comprising of grease and oil lubricant. Both types are suitable for ultra-speed working conditions.

Single-row cylindrical roller bearings are designed with a separable structure that is comprised of both inner and outer rings, and feature a high load capacity that is suitable for large electrical machinery, machine tool spindles and gearboxes and more. Based on the different structures, we offer a variety of types, including the N-type, NU-type, NUP-type and NF-type. Users can choose the right bearing for their needs.

Types NU and N are suitable as free-end bearings. Types NJ and NF can sustain limited axial loads in one direction. Types NUP can be used as fixed-end bearings.

Our recommendations are below, based on the different single row cylindrical roller bearing structures.

N-type Single Row Cylindrical Roller Bearings(RIN,RN)

N-type bearings support only a radial load. The inner ring features ribs on both sides, and the outer ring is cylindrical with no ribs, which allow the bearing to shift in both directions in a relative axial direction between the shaft and bearing seat. These bearings are suitable for ball mills, aligning belt bearings, transmission boxes, gear transmission devices, mud pumps and more.
