UC315 Insert Bearing for Electrician Applications

The NTN UC315 is a new insert bearing designed for electrician tools and related mechanical assemblies. It suits maintenance technicians and original-equipment manufacturers who need a direct replacement or a component for new build projects.

Mounting and Space Considerations

The bearing measures 75 mm bore, 160 mm outside diameter and 43 mm width, so the surrounding housing and shaft must match these dimensions exactly. Correct fitment frees up radial and axial play in the assembly, allowing the connected tool or machine to run smoothly without additional spacers or adapters.

Ready-to-Install Unit

Supplied as a complete insert bearing, the UC315 arrives assembled and lubricated, eliminating the need for separate rolling elements, cages or seals. This reduces assembly time and removes the risk of contamination during on-site build.

Questions about this item

What is the maximum inner diameter this UC315 insert bearing can accommodate?

The UC315 insert bearing has an inner diameter of 75mm, which determines the shaft size it fits directly.

How much heat can the NTN UC315 dissipate during continuous operation?

The UC315 is a mechanical rolling-element bearing; heat generation depends on applied load, speed and lubrication rather than a fixed dissipation rating.

Which housing or pillow block is required to mount this 75x160x43mm insert bearing?

The UC315 fits standard UC315-series pillow blocks or flanged housings with a 160mm outer diameter and 43mm width.
