SKF 6203-2RSH/C4 1 Row Ball Bearing - 17 mm ID, 40 mm OD

This ball bearing is a sealed single-row deep-groove component designed to support radial and axial loads in rotating equipment. It is manufactured from steel with a cylindrical bore and an internal clearance graded C4, enabling reliable operation where precise running clearance is required.

• Sealed construction reduces lubricant loss and contaminant ingress
• Sheet-metal cage lowers rotational mass for smoother operation
• Dynamic load capacity 9.95 kN enables sustained operational loading
• Static load capacity 4.75 kN resists deformation under stationary loads
• Limiting speed 12,000 r/min supports high-speed rotation applications
• Internal clearance C4 accommodates thermal expansion and shaft misalignment

• Suitable for motor shafts requiring sealed bearings
• Ideal for high-speed spindle assemblies up to 12,000 r/min
• Used with gearboxes needing moderate dynamic loading
• Can be used for precision conveyors with C4 clearance demands
• Appropriate for rotating instruments with a cylindrical bore

The bearing's steel construction provides hardness and fatigue resistance suited to rolling-contact conditions.

The sealed ends limit contamination and retain lubricant, reducing the frequency of re-lubrication compared with open designs.

C4 denotes greater internal radial play than standard, so shaft fits should permit slight axial and radial movement during operation.

The thin metal cage offers low thermal mass, allowing Faster heat dissipation from the rolling elements during sustained high-speed use.
