SKF Bearing Unit Accessory For Use With Needle Roller Bearing, IR 12X16X20

This bearing unit accessory serves as an inner race designed to be used with needle roller bearings in industrial assemblies. It provides a hardened running surface for rollers where a compatible shaft or housing cannot be used as the raceway, enabling Compact bearing arrangements in automation and mechanical systems.

• 12mm inside diameter offers precise shaft fit and alignment
• Inner ring form reduces required housing machining complexity
• Compatible with needle roller bearings for Compact radial load support
• Compact profile aids tight-installation space optimisation

• Suitable for automation actuators requiring Compact bearing solutions
• Ideal for electrical motors where a separate raceway is necessary
• Used with needle roller bearings in gearbox intermediate shafts
• Can be used for mechanical linkages in robotics and assembly lines

The ring is supplied as a hardened inner race designed to provide a Durable running surface compatible with needle rollers, reducing localised wear between rollers and shaft.

Its precise 12mm internal diameter maintains concentricity with mating shafts, helping to preserve bearing alignment and reduce vibration in rotating equipment.

Yes, it functions as a replacement inner race where the shaft cannot act as the track, allowing refurbishment of assemblies without extensive shaft replacement.
