SKF QJ 203 N2MA/C2L 1 Row Ball Bearing - 17 mm ID, 40 mm OD 12 mm Race Width

This ball bearing is a single-row four-point-contact component designed to accommodate combined radial and axial loads in Compact rotating assemblies. It operates in high-speed applications where precise contact geometry and controlled internal clearance are required, and it is supplied with an open end and a parallel bore for direct shaft mounting.

• 30000 r/min limiting speed enables high-speed operation
• C2 internal clearance improves axial stiffness under load
• 35° contact angle provides enhanced axial load capacity
• Machined metal cage maintains ball spacing at high rpm
• Steel balls deliver consistent rolling-contact performance
• 17 kN dynamic rating supports substantial operational loads

• Suitable for Compact motor spindle assemblies
• Ideal for precision rotary indexing units
• Used with small gearbox shafts requiring axial load support
• Can be used for high-speed pump rotor bearings
• Used for combined radial and axial load-bearing shafts

It fits directly onto a shaft with a parallel bore and open end for straightforward axial positioning.

The four-point-contact layout shares axial loads through a 35° contact angle to sustain thrust in either direction.

The rolling elements are steel balls combined with a machined metal cage to preserve rolling contact under cyclic loads.

Maintain rotational speed at or below 30 000 r/min to align with the specified limiting speed and preserve service life.
