SKF 21308 E Series Roller Bearing, 40mm Bore Size, 107kN Dynamic Load Rating - 21308 E
This roller bearing is designed to support radial loads in rotating machinery where a cylindrical bore and Compact width are required. It operates as a single-row cylindrical-bore bearing with a metal cage and steel rolling elements, intended for applications requiring a balance of dynamic and static load-carrying capacity at moderately high-speed operation.
Features and Benefits:
• Dynamic capacity 107 kN provides sustained load-carrying performance
• Static capacity 108 kN resists deformation under heavy stationary loads
• Sheet-metal cage reduces friction and maintains roller spacing
• Steel rollers and rings ensure wear‑resistant rolling contact
• Internal clearance class CN accommodates moderate radial displacement
• Limiting speed 9,500 r/min permits high-speed rotation where required
• Static capacity 108 kN resists deformation under heavy stationary loads
• Sheet-metal cage reduces friction and maintains roller spacing
• Steel rollers and rings ensure wear‑resistant rolling contact
• Internal clearance class CN accommodates moderate radial displacement
• Limiting speed 9,500 r/min permits high-speed rotation where required
Applications
• Suitable for industrial gearboxes with cylindrical bores
• Ideal for shafts requiring 40 mm bore support
• Used with rotating assemblies needing single-row load support
• Can be used for drives operating up to 9,500 r/min
• Suitable for machines where metal-cage robustness is needed
• Ideal for shafts requiring 40 mm bore support
• Used with rotating assemblies needing single-row load support
• Can be used for drives operating up to 9,500 r/min
• Suitable for machines where metal-cage robustness is needed
What bore type does this unit require for mounting?
It is designed for a cylindrical-bore mounting arrangement to fit onto plain shafts.
How does the internal clearance affect alignment tolerance?
The CN clearance provides moderate internal play to accommodate thermal expansion and slight misalignment without excessive preload.
What materials compose the rolling elements and retention device?
The rollers and rings are MADE of steel while the cage is formed from sheet metal.
How does the bearing handle stationary heavy loads?
The static rating of 108 kN indicates resistance to permanent deformation when subjected to substantial stationary forces.
