Cylindrical Roller Bearing:NF202

Description

Basic Parameters

The NF202 cylindrical roller bearing is a single-row, non-locating bearing featuring an outer ring with a single rib and an inner ring without ribs, allowing for separable installation and moderate axial displacement in one direction. It has an inner diameter of 15 mm, outer diameter of 35 mm, and width of 11 mm, constructed from high-carbon chromium bearing steel (ISO 683-17) for excellent fatigue resistance and dimensional stability. The bearing incorporates cylindrical rollers guided by a pressed steel cage, providing a dynamic radial load rating (Cₙ) of 10.8 kN and a static radial load rating (Cₒₙ) of 10.2 kN. With a maximum operating speed of 15,000 rpm under oil lubrication, it offers low friction and high rotational accuracy, suitable for applications requiring high radial load capacity such as electric motors, pumps, conveyors, and textile machinery. Its separable design simplifies maintenance by allowing independent mounting of the inner ring and roller assembly, while the outer ring rib ensures reliable roller guidance under heavy radial loads.

Product Application

The NF202 cylindrical roller bearing is engineered for versatile industrial applications that demand robust radial load handling with controlled unidirectional axial movement. Its single-row design with a ribbed outer ring and ribless inner ring makes it ideal for systems requiring separable component installation, such as **electric motors** where the inner ring can be mounted directly on the shaft while the outer ring integrates with the motor housing, streamlining assembly in confined spaces. In **centrifugal pumps** and **compressors**, the bearing’s 15,000 rpm speed capability and low friction coefficient reduce energy losses during high-speed rotation, while the outer ring rib ensures stable roller guidance under radial forces generated by impellers or pistons, minimizing vibration and noise.
