NSK tapered roller bearings

303/32, HR 30203 J and 100 KBE 31+L illustrate three structures. The first contains a slash; the second surrounds its base with HR and J; the third combines an initial number, KBE and 31+L. The catalog identifies the last example as a double row bearing. Retain the plus sign, spaces and letters without assigning undocumented materials or performance to individual groups. Product name and configuration establish the component scope.

In a gearbox, a tapered bearing may locate the shaft beside a gear. Its orientation relative to the other bearing matters when thrust acts in opposite directions. Record orientation, spacers, shoulders and adjustment parts; an isolated bearing photograph misses this context. Keep separately removed components identified by machine side to prevent mixing different assemblies.

Tell MR Accesorios Industriales whether you need a complete reference or individually identified components. Include every marking, quantity, verified dimensions and an axial arrangement view. Following a failure, surface condition and observed clearance provide context but do not replace identification. Include the machine's adjustment specification when available. Neither a partial designation nor a similar code justifies a new adjustment or confirms the original arrangement.
