SKF RNA 6904 Series Roller Bearing, 25mm Inside Diameter, 37mm Outside Diameter - RNA 6904
This roller bearing is designed for applications requiring compact, radial load support in rotating assemblies. It employs a line of cylindrical rollers within a guided cage to enable smooth rotation at elevated speeds while maintaining load capacity for demanding mechanical systems.
Features and Benefits:
• High dynamic capacity for prolonged operational life • Elevated static strength for heavy radial loading • Suitable for high-speed operation up to 17,000 r/min • Manufactured from bearing steel for fatigue resistance • Sheet steel cage ensures secure roller retention
Applications
• Suitable for automation actuators requiring Compact radial support • Ideal for drivetrain components in electrical machinery • Used for precision rotary modules in electronics manufacture • Can be used for transmission shafts in mechanical systems
What construction elements aid in roller guidance and spacing?
A thin-profile sheet steel cage maintains roller alignment and spacing to reduce friction and prevent skidding during rotation.
How does material selection affect fatigue performance?
The bearing steel composition delivers enhanced fatigue resistance for repeated radial loading cycles common in industrial equipment.
What load capacities should designers consider for static conditions?
The component provides a high static load capacity suited to applications where residual or parked loads are significant.
Are there speed limitations to account for in design?
The specified operational speed limit should be observed to prevent excessive heat and maintain service life in high-rpm installations.
Does the product meet environmental substance restrictions?
It conforms to RoHS requirements limiting hazardous substances for use in compliant equipment.
