NTN UC311D1 Insert Bearing for Maintenance

The ZIBOO NTN UC311D1 insert bearing measures 55x120x34mm and is supplied as a single unit in a box. It is intended for technicians and maintenance teams who need a direct replacement bearing for rotating equipment. The red finish aids visual identification during inspection routines.

Three-Year Parts Coverage and One-Year Labor

The bundle includes a parts warranty lasting three years and a labor warranty lasting one year. These terms reduce the cost risk if the bearing fails prematurely and simplify claims handling for workshops and facilities teams.

Steel Construction with Standard Mounting

The bearing is built from hardened steel to withstand radial and axial loads in continuous operation. Its 55mm inner diameter, 120mm outer diameter and 34mm width match common housing bores and shaft seats, allowing straightforward press-fit installation without special adapters.

Questions about this item

How often should the UC311D1 insert bearing be inspected or replaced under normal operating conditions?

The bearing is supplied new with a three-year parts coverage period; schedule inspection intervals based on load, speed and contamination levels in your application.

Which operating limit — speed, temperature or load — is reached first during continuous running?

The limiting factor depends on the specific shaft speed, radial load and ambient temperature in your installation; consult the NTN catalogue for the exact rating charts.

Does the bearing generate noticeable heat or noise when run all day?

A correctly mounted and lubricated UC311D1 runs quietly with minimal temperature rise; abnormal heat or noise usually indicates misalignment, insufficient lubrication or overload.
