LM78310

Look-alike part numbers are the usual way a stores ticket goes wrong on a inch tapered roller bearing (cone and cup). Do not substitute LM78349/LM78310, which share the title but are a different inch set. Match cone LM545849 with cup LM545810. The 1.9685 in bore is a starting check, not a license to mix the LM783xx pair.

The envelope to write on the ticket is 1.9685 in bore class (confirm full envelope on the listing). That geometry belongs to LM545849/LM545810, an inch tapered roller bearing (cone and cup). Measure the removed part or the housing before you trust a faded stamp.

Review LM545849/LM545810 bearing 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.
