SKF SRB Series Roller Bearing, 35mm Inside Diameter, 80mm Outside Diameter - 21307 CC
This roller bearing is a two-row spherical design intended to accommodate heavy radial and moderate axial loads in rotating assemblies across industrial systems. It combines hardened steel rolling elements with a sheet-metal cage and is suited to applications requiring robust load capacity and defined internal clearance for predictable operating behaviour.
Features & Benefits
• Dynamic capacity 79.2 kN provides high sustained radial load support
• Static capacity 72 kN resists heavy static or shock loading
• Limiting speed 12000 rpm enables high-speed usage
• Internal clearance CN ensures controlled running and preload options
• Cylindrical bore offers straightforward shaft mounting
• Sheet-metal cage reduces friction and improves running stability
• Static capacity 72 kN resists heavy static or shock loading
• Limiting speed 12000 rpm enables high-speed usage
• Internal clearance CN ensures controlled running and preload options
• Cylindrical bore offers straightforward shaft mounting
• Sheet-metal cage reduces friction and improves running stability
Applications
• Suitable for high-load gearbox shafts in automation systems
• Ideal for conveyor drive rolls in material handling equipment
• Used with electric motor shafts subject to axial misalignment
• Can be used for rotary joints in production-line machinery
• Suitable for bearing arrangements in heavy-duty pumps and compressors

What reference speed should be used for routine calculations?
Use the reference speed of 7300 r/min for fatigue and thermal assessments.
How does the bearing cope with misalignment in assemblies?
The spherical-roller configuration accommodates shaft misalignment while maintaining load distribution across rollers.
What are the essential shaft and housing contacts to check during installation?
Verify da greater than or equal to 44mm and Da less than or equal to71mm for correct seating and ensure fillet radii do not exceed 1.5mm at contact edges.
What mass should be considered for dynamic balancing of rotating systems?
Account for a bearing mass of 0.54kg when calculating rotor inertia and balance corrections.
