Questions about this item
Does the NTN UC316 insert bearing come with a housing or mounting hardware?
The product is the insert bearing only, measuring 80x170x45mm. A pillow block or flange housing and any set screws or adapter sleeves must be purchased separately to suit the shaft and mounting arrangement.
How do I confirm the NTN UC316 is the correct version for my shaft size?
The model number 316 indicates the bearing series and bore code. The 80mm bore diameter is the critical figure; match this to your shaft diameter and verify the 170mm outside diameter and 45mm width fit the housing you intend to use.
What does the 80x170x45mm size mean once the bearing is installed in a machine?
The 80mm bore fits the shaft, the 170mm outside diameter seats into the housing bore, and the 45mm width determines the axial space the unit occupies. These three dimensions fix the shaft centre height and the overall envelope in the assembly.
