NTN 1313 Self Aligning Ball Bearing

The ZIBOO NTN 1313 is a self-aligning ball bearing designed for applications requiring tolerance of shaft misalignment. It suits maintenance engineers and electricians who need a reliable rolling element for motors, pumps or conveyor systems. The bearing accommodates angular displacement between inner and outer rings, reducing stress on surrounding components. Supplied as a single unit in a box, it is ready for immediate installation.

Thermals noise and power draw

As a passive mechanical component, the bearing generates no electrical noise and draws no power during operation. Heat generation depends entirely on the host machine's load, speed and lubrication regime rather than the bearing itself. Proper grease selection and regular relubrication keep running temperatures within normal limits for the application. No active cooling or acoustic damping is required from the bearing.

Build quality and mounting implications

The bearing measures 65 mm bore, 140 mm outside diameter and 33 mm width, matching the NTN 1313 series envelope. Its self-aligning internal geometry allows the inner ring and ball assembly to swivel slightly, compensating for housing distortion or shaft deflection. The red finish indicates the manufacturer's standard corrosion-resistant coating. Fitment follows standard shaft and housing tolerance tables for this bore and outside diameter.

Questions about this item

How do I press the 65 mm bore of the NTN 1313 onto the shaft without damaging the self-aligning races?

Apply even force only to the inner ring using a bearing press or sleeve that matches the 65 mm bore; never hammer the outer ring or the cage, as this brinells the raceways and destroys the self-aligning capability.

When should I plan to relubricate or replace the NTN 1313 bearing in continuous service?

Relubricate with a compatible grease at intervals dictated by speed, load and temperature; replace the unit once inspection shows raceway pitting, excessive radial play or seal degradation.

What operating condition reaches its limit first on the NTN 1313 during sustained high-speed runs?

The self-aligning design tolerates misalignment, but the 33 mm width limits heat dissipation, so bearing temperature typically hits its permissible ceiling before fatigue life expires.
