SKF NU 312 ECJ/C3 60 mm ID Roller Bearing, 130 mm OD

This roller bearing provides radial support for rotating shafts in industrial equipment where cylindrical bore interfaces are required. It is intended for single-shaft assemblies operating with a single row of rollers and an open-end configuration, suited to high-speed rotational applications in automation and mechanical systems.

• Sheet metal cage reduces mass and aids thermal dissipation
• Internal C3 clearance accommodates shaft expansion at temperature
• Dynamic capacity of 173kN supports heavy radial loads
• Static capacity of 160kN resists deformation under standstill loads
• Rated limiting speed 6700r/min for high-speed operation
• Cylindrical bore enables straightforward mounting and axial displacement

• Suitable for spindle and motorised roller in automation
• Ideal for gearbox radial support where axial positioning is free
• Used with conveyor drive shafts in material handling systems
• Can be used for high-speed test rigs in electronics manufacturing

The bearing uses a sheet metal cage which lowers centrifugal forces at speed and improves heat transfer compared with heavier cages.

The C3 clearance provides increased internal play to accommodate thermal expansion and shaft misalignment without premature contact.

The open-ended design and cylindrical bore permit axial movement of the shaft, locating shoulders or rings should control axial position where required.

With a dynamic rating of 173kN it maintains rolling-element life under continuous radial loading, while the static rating of 160kN limits permanent deformation during overload or stationary loads.
