Industrial angular-contact bearing

The ZIBOO NTN 7313 is a precision angular-contact ball bearing built for electricians and maintenance technicians who need reliable rotational performance in test equipment and power-tool applications. Its 65x140x33mm dimensions suit shafts and housings that match this envelope, and the red finish provides quick visual identification in a busy workshop. The single-unit pack keeps inventory simple for targeted replacements.

Low-friction operation with minimal heat

Angular-contact geometry handles combined radial and axial loads while generating little friction, so running temperatures stay low during continuous use in motor spindles or test rigs. The design runs quietly, reducing audible distraction when equipment operates near workstations. Efficient load distribution also limits power loss, helping driven tools maintain their rated output without extra thermal load.

Fits standard 65 mm bore housings

The 65 mm bore seats directly on shafts of that size, while the 140 mm outside diameter matches common housing bores for this bearing series. A 33 mm width leaves room for standard circlips or locknuts without requiring special spacers. No additional lubrication fittings are needed beyond normal maintenance schedules, freeing up design space around the mounting area.

Questions about this item

How do I install the 7313 bearing with its 65mm bore and 140mm outer diameter without damaging the 33mm width?

Press the inner ring onto a 65mm shaft and the outer ring into a 140mm housing using a sleeve that contacts only the ring being driven; never hammer directly on the 33mm wide races or the red finish.

What maintenance will the NTN 7313 angular contact ball bearing need after installation?

Relubricate at intervals suited to speed and load; inspect the red finish for fretting and replace the bearing if axial play exceeds the manufacturer's limit for the 7313 series.

Which limit appears first on the 7313 bearing during sustained high-speed operation?

The contact-angle design reaches its permissible speed limit before the 33mm wide races overheat, so monitor temperature rise at the 65mm bore and 140mm OD to stay within the NTN 7313 rating.
