In a split plummer block housing, the SR lock ring keeps the bearing outer ring in its axial position. Seated in the housing bore, it stops the outer ring from shifting sideways, so the bearing stays where the design intends it to sit. Skip this part and the assembly loses its guidance, which shows up as uneven wear. MR Industrial Accessories LLC supplies the Timken SR line for SNT and FSNT housings.

Reading an SR reference is straightforward once you know the pattern. The digits before the X give the nominal housing size, and the figure after the X gives the ring width. That is how references like SR52X3.5, SR62X6 and SR80X9 sit side by side in the same line: same family, different housing sizes and thicknesses. Rings in this range serve the 500 and 600 series, the SNTN 3000 Light Series and FSNT housings, matched to each housing size. Share the full part number and we will point you to the right variant.

Typical applications are transmission points on belt conveyors, bucket elevators, mills, mixers, centrifugal pumps and industrial fans. In food processing, cement, mining and aggregate plants, an SNT housing with its SR ring is a routine choice for shafts running at moderate speed under radial load. Paper machines, steel mills and effluent treatment plants use the same arrangement, whether the housing is bolted to a steel frame or set on a concrete bed.

Selection starts with two part numbers: the housing and the bearing that goes into it. The ring has to suit the outer ring diameter and the housing width. Get the thickness wrong and you end up with either axial play or a locked bearing. At mounting, clean the housing first, confirm the two halves close without forcing, and lubricate the contact surfaces. Shaft alignment against the housing matters as well, since a ring that does not seat properly brings vibration and seal wear.

On interchangeability, Timken SR rings are made for the SNT and FSNT housings of the same line. Other manufacturers run comparable systems, yet ring height and diameter can differ slightly from one brand to another, so mixing parts without checking the seat is not recommended. For a replacement, send the housing part number or the bearing model and we will identify the compatible option.
