SKF NKIA 5902 Cylindrical 15 mm ID Roller Bearing, 28 mm OD

This roller bearing is a cylindrical-bore, grooved-race component designed to support radial loads in rotating assemblies. It is manufactured in steel and intended for installations requiring Compact support and continuous operation at elevated shaft speeds. The bearing features standard internal clearance and a construction suited to applications where sustained dynamic and static load capacity is required.

• 11.2 kN dynamic load rating for sustained operational loads
• 153 kN static load capability to resist heavy stationary forces
• 22,000 r/min limiting speed for high-speed rotational applications
• CN internal clearance to accommodate thermal and assembly variation
• Steel rollers and races for robust wear resistance and longevity

• Suitable for high-speed spindles with Compact shaft sizes
• Ideal for machine-tool support where radial loads predominate
• Used with rotating shafts requiring robust static load support
• Can be used for industrial gearboxes operating at elevated speeds
• Suitable for Compact actuator assemblies needing Durable bearings

A smooth cylindrical shaft is required to match the bearing's cylindrical bore.

The grooved race allows stable roller guidance while CN clearance accommodates small positional variations.

The bearing uses steel rollers and races which provide hardness and surface durability under load.

The race width determines the axial envelope, specified as 18 mm for this component.
