SKF NA 4907.2RS Cylindrical 35 mm ID Roller Bearing, 55 mm OD

This roller bearing provides axial and radial support for rotating assemblies in machinery where sealed protection and defined internal clearance are required. It is designed for single-row operation with a cylindrical bore and shielded ends to restrict contamination while allowing continuous rotation at specified speeds. The component is constructed from bearing steel with a sheet-metal cage for guided rolling elements and is intended for installations that demand specified load capacities and speed limits.

• 31 kN dynamic load capacity for sustained operational stresses
• 43 kN static load rating to resist heavy stationary loads
• CN internal clearance for predictable axial displacement control
• 4,800 r/min limiting speed for moderate-speed applications
• Shielded end design to limit ingress while permitting rotation

• Suitable for moderate-speed gearbox roller supports
• Used with electric motor shaft assemblies requiring protection
• Ideal for conveyor idler shafts in manufacturing lines
• Can be used for pump shaft bearing support in fluid systems
• Used for machine-tool peripheral component rotation control

Bearing steel provides the hardness and wear characteristics required for prolonged rolling-contact life.

The sheet-metal cage maintains consistent roller spacing and reduces frictional heating during continuous rotation.

A cylindrical bore allows direct mounting onto a plain shaft with interference or adaptor fitments as appropriate.

Shielded ends reduce contamination ingress compared with open designs, which can extend lubrication service periods.

A single-row arrangement is optimised for combined radial loads with limited axial load capacity relative to multi-row types.
