NTN UC313 Insert Bearing 65x140x39mm
The NTN UC313 is a new insert bearing measuring 65 millimetres inner diameter by 140 millimetres outer diameter with a 39 millimetre width. It is designed for electricians and maintenance technicians who need a reliable replacement unit for motor shafts or conveyor rollers. The bearing carries the NTN brand and model designation 313 for clear identification.
Suits electricians replacing worn shaft bearings
This part suits professionals swapping out a failed insert bearing on compatible equipment where the 65 by 140 by 39 millimetre envelope matches the housing. It is not for buyers who need a different bore size, a narrower width, or a complete pillow block assembly rather than the insert alone. The component addresses a direct dimensional match only.
65x140x39mm envelope decides fit
The single specification that decides compatibility is the 65 millimetre inner diameter combined with the 140 millimetre outer diameter and 39 millimetre width. If the host housing or shaft does not match these three dimensions exactly, the bearing will not seat or locate correctly. No other feature overrides this dimensional requirement.
