SKF RNA 4902 Series Roller Bearing, 20mm Inside Diameter, 28mm Outside Diameter - RNA 4902
This roller bearing is a Compact needle-type unit designed to support rotary shafts in confined assemblies where high radial load capacity and space efficiency are required. It is constructed from bearing steel with a sheet-steel cage and functions as a single-row element suitable for applications demanding elevated rotational speeds and controlled load performance.
Features and Benefits:
• High rotational capability allows operation up to 22,000 r/min
• Dynamic capacity of 11.2 kN improves continuous load handling
• Static rating of 15.3 kN resists heavy stationary loads
• Sheet-steel cage reduces internal friction and wear
• Single-row layout minimises axial space for Compact installations
• Dynamic capacity of 11.2 kN improves continuous load handling
• Static rating of 15.3 kN resists heavy stationary loads
• Sheet-steel cage reduces internal friction and wear
• Single-row layout minimises axial space for Compact installations
Applications
• Suitable for high-speed motor and spindle assemblies
• Ideal for transmissions in Compact mechanical systems
• Used with precision gearboxes requiring high radial capacity
• Can be used for rotating rollers in lightweight conveyors
• Appropriate for pneumatic actuator shafts in limited envelopes

What material composes the rolling elements and races?
Both the rollers and raceways are MADE from bearing steel, providing hardened contact surfaces.
How does the cage construction affect maintenance intervals?
The sheet-steel cage stabilises roller guidance, which helps lower wear rates and can extend service intervals compared with unsecured rollers.
What limiting factor must be considered at maximum shaft speed?
Thermal build-up and the lubrication regime become critical when approaching 22,000 r/min and should be managed to prevent overheating.
How does the bearing perform under stationary overload conditions?
Its static load rating of 15.3 kN indicates the capacity to withstand substantial non-rotational loads without permanent deformation.
What is the configuration impact on installation space?
The single-row needle arrangement offers a narrow radial profile, enabling integration into tight axial and radial envelopes.
