UNH,UVH, LSH and LSJ types

List of combinations of Shaft diameter (bearing model number) and Shell outer diameter

A separate Roller with different standard dimensions is designated as a “B-type Roller” in the JRC, and is compatible with production as shown in the table below. At the time of request, check the structural drawings of each Roller and instruct the desired dimensions, specifications, etc. It also supports special machining such as threading and pin holes at the shaft end. (See the following figure, machining example of shaft end.)
