SKF NU 209 ECP/C3 45 mm ID Roller Bearing, 85 mm OD

This roller bearing is a single-row cylindrical type designed to support radial loads in rotating assemblies where controlled internal clearance and consistent running speed are required. It is finished with protective shields and employs a non-metallic cage to guide the rollers, making it suitable for machine shafts and rotating housings that demand predictable bearing behaviour and straightforward integration.

• C3 internal clearance provides reduced preload and compensates misalignment
• Non-metallic cage lowers noise and reduces lubrication retention issues
• Shielded end design limits contaminant ingress during operation
• 64 kN static capacity resists deformation under stationary loads
• 69.5 kN dynamic capacity supports sustained rotational loading
• 9500 r/min limiting speed allows high-speed duty when lubricated correctly

• Suitable for medium-duty industrial gearboxes
• Ideal for machine tool spindle supports at moderate speed
• Used with conveyor drives requiring steady radial support
• Can be used for electric motor shaft assemblies
• Suitable for rotating cylinders in printing equipment

It uses a cylindrical bore that fits on plain journal shafts without interference.

The non-metallic cage reduces metal-to-metal wear and can extend re-lubrication intervals in clean environments.

Shields provide limited protection against dust and light debris but are not sealed against fluids.

The increased clearance compensates for thermal expansion and shaft deflection, allowing looser axial tolerance in assemblies.
