# 30310: 50 × 110 × 29.25 mm Field Notes

The envelope to write on the ticket is 50 × 110 × 29.25 mm. That geometry belongs to 30310, a metric tapered roller bearing for crushers. Measure the removed part or the housing before you trust a faded stamp.

Typical duty includes crushers, mining equipment, and other 30310 combined-load positions. Material on this listing is chrome steel. If your equipment sits outside that range, say so on the request rather than forcing a familiar part number.

Do not substitute 32210 (50×90×24.75 mm) or 30309/30311. 30310 is 50×110×29.25 mm — a different OD and width from 32210. P6 and a complete set are listed; specify clearance when you order.

Review 30310 on the TFL Bearing Made-in-China listing. Shandong TFL Bearing Co., Ltd can confirm stock, packing, and any OEM marking once the drawing or sample is attached.
