SKF 21311 EK Series Roller Bearing, 55mm Inside Diameter, 29mm Race Width - 21311 EK
This roller bearing is a single-row tapered solution designed to support rotating shafts in demanding mechanical assemblies. It combines steel rolling elements with a tapered bore and sheet‑metal cage to manage combined radial and axial loads at moderate to high operating speeds within industrial machinery contexts.
Features and Benefits:
• 159 kN dynamic load capacity for sustained operational stresses
• 166 kN static load capacity for high static force resistance
• Tapered bore enabling secure press-fit assembly on tapered shafts
• Sheet‑metal cage ensuring accurate roller guidance and reduced friction
• CN internal clearance permitting precise axial and radial play control
• Rated for 7,500 r/min to accommodate high-speed rotation demands
• 166 kN static load capacity for high static force resistance
• Tapered bore enabling secure press-fit assembly on tapered shafts
• Sheet‑metal cage ensuring accurate roller guidance and reduced friction
• CN internal clearance permitting precise axial and radial play control
• Rated for 7,500 r/min to accommodate high-speed rotation demands
Applications
• Suitable for heavy machinery bearing housings with combined loads
• Used with gearbox shafts requiring tapered-bore mounting
• Ideal for rotating equipment operating at elevated speeds
• Can be used for replacement in assemblies with 120 x 55 x 29 dimensions
• Suitable for industrial drives needing steel roller durability
• Used with gearbox shafts requiring tapered-bore mounting
• Ideal for rotating equipment operating at elevated speeds
• Can be used for replacement in assemblies with 120 x 55 x 29 dimensions
• Suitable for industrial drives needing steel roller durability
What material composes the rolling elements and races?
The rollers and raceways are manufactured from steel to provide wear resistance and load support.
How does the cage design affect maintenance intervals?
The sheet‑metal cage maintains roller spacing and reduces contamination‑related wear, which can extend bearing service life under proper lubrication.
What clearance grade does the bearing employ for axial positioning?
It uses CN internal clearance to balance axial movement and preload sensitivity in assemblies.
What mounting considerations apply for the tapered bore?
A tapered bore requires an appropriate tapered adapter or sleeve to achieve correct interference fit and axial location on the shaft.
