The SEALMASTER SLS 100 series insert bearing is a ball bearing with an extended inner ring and set screw locking, made to be mounted in split or solid housings. It handles radial loads and some axial thrust, and it can be replaced without changing the housing. MR Industrial Accessories LLC supplies this line to industrial customers across the United States and in several Latin American countries.

The SLS 100 series code tells you the insert type and its size. In SLS-120S, SLS means the insert bearing series with extended inner ring and set screw locking. The number 120 gives the nominal shaft diameter in hundredths of an inch, so 1.20 inches. The final S is a construction variant, often related to the seal type or the outer ring shape. Reading the code this way helps you identify any reference in the series and order the right replacement.

These insert bearings are common in belt conveyors, bucket elevators, mixers, mills, fans, centrifugal pumps, and food and beverage machinery. They also show up in agricultural equipment such as seeders and harvesters, and in aggregate processing plants. Because they fit split or flanged housings, maintenance is simpler and downtime is shorter when the insert needs to be changed due to wear or failure.

When choosing an insert, consider the shaft diameter, the load type (radial, axial or combined) and the environment. Sealing matters: for dusty, humid or frequently washed areas, pick a variant with a higher-protection seal. Lubrication should match the rotation speed and working temperature. During mounting, check housing alignment and tighten the set screws onto the shaft; poor locking causes vibration and early wear.

Insert bearings are often interchangeable between brands that share the same mounting standard, since they are identified by shaft diameter and main dimensions. Still, sealing, internal clearance or locking system can differ from one maker to another. To replace a SEALMASTER SLS 100, compare the critical dimensions and the locking type.
