ZIBOO NTN 21316 Spherical Roller Bearing

The ZIBOO NTN 21316 is a spherical roller bearing designed for applications that require accommodation of misalignment and heavy radial loads. It suits maintenance engineers and industrial technicians who need a replacement component matching the 21316 designation. The bearing features an 80 mm bore, a 170 mm outside diameter and a 39 mm width. It is supplied new and ready for installation in compatible housings or shafts.

No bundled accessories or software included

This product is sold as a single bearing unit without additional seals, lubricants, mounting sleeves or tools.

Questions about this item

When will the NTN 21316 spherical roller bearing need replacement or relubrication?

Relubrication intervals depend on load, speed, and contamination; inspect seals and grease condition regularly and replace the bearing when vibration or temperature rise exceeds normal operating limits.

What is the first limiting factor for the 80x170x39 mm bearing under sustained heavy load?

The dynamic load rating of the NTN 21316 design determines the fatigue life limit; continuous operation above that rating will cause subsurface rolling-contact fatigue first.
