The SR lock ring is the component that locks the bearing axially inside the split plummer block housing. It is placed in the housing and secures the outer ring against displacement, so that the bearing operates in its correct position without hitting the sides. It is a small but critical part: without it, the assembly loses guidance and premature wear appears. MR Accesorios Industriales carries the Timken line for SNT and FSNT housings.

The SR designation is read together with the housing size: the number that follows indicates the nominal bore diameter of the housing and the decimal value, the width of the ring. That is why references such as SR52X3.5, SR62X6 or SR80X9 coexist: the first figure identifies the housing size and the second, the thickness of the part. The 500/600 series and the SNTN 3000 Light Series and FSNT lines use these rings according to the housing size. Send us the complete code and we will tell you the corresponding variant.

These rings are used in split plummer block housings of power transmission equipment: belt conveyors, bucket elevators, mills, mixers, centrifugal pumps and industrial fans. In food, cement, mining and aggregate processing plants in Argentina, the SNT housing with its SR ring is a common solution for shafts rotating at moderate speeds and receiving radial load. They also appear in paper machines, steel mills and effluent treatment plants, where assembly is done on a steel structure or concrete bedplate.

To choose the correct ring, start from the housing code and the bearing that is mounted. The ring must match the outer ring diameter and the housing width; if the thickness is not adequate, the bearing is left with axial play or binding. During assembly, clean the housing, verify that the two housing halves close without forcing and lubricate the contact surfaces. Shaft alignment with respect to the housing is key: a poorly seated ring generates vibration and wear on the seal.

As for interchangeability, Timken SR rings correspond to the housings of its own SNT and FSNT line. Other manufacturers use equivalent systems, but the height and diameter of the ring may vary slightly between brands. It is not advisable to mix parts of different origin without verifying the seating. If you need to replace a ring, send us the housing code or the bearing model and we will tell you the compatible alternative.

If you have the housing code at hand, write to us on WhatsApp and we will quote the SR ring you need. We can also advise you on the bearing and seals that complete the assembly. MR Accesorios Industriales works with the Timken line so that the assembly is properly resolved from the first attempt.
