The DBH 6774Sil radial shaft seal is a lip seal mounted on the shaft to retain lubricant and block the ingress of dust, water or particles. Due to its dimensions of 41.20 mm shaft, 49.28 mm housing and 6.20 mm height, it is used in gearboxes, pumps, electric motors and power transmission equipment where axial space is limited. It is an official brand that MR supplies, with the seal quality that a plant shutdown demands.

This item is a radial shaft seal from the DBH line, identified by the code 6774Sil. Its dimensions are 41.20 mm shaft diameter, 49.28 mm housing diameter and 6.20 mm height. The LMx design corresponds to a single lip with spring, intended for rotating shafts with permanent lubrication. The lip elastomer runs on a ground surface and the outer metal case guarantees a firm fit in the housing. It is a direct replacement part, not a generic component.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain transmission equipment. In all cases it fulfills the function of confining the oil or grease inside the assembly and preventing contaminants from entering from outside. Due to its reduced height, it is common in spaces where there is no room for wider seals. It is also used as a secondary closure in split plummer block housings and hubs.

For correct installation, verify that the shaft diameter is within the recommended tolerance and that the contact surface has no burrs or marks. Lubricate the lip with the same grease or oil as the equipment before inserting it, and do so with a support tube that rests on the case, never on the lip. If the housing has a shoulder, respect the depth so that the seal is not deformed. Poor alignment shortens the service life of the seal.

If you need a nearby size or an equivalent, send us the code 6774Sil along with the shaft, housing and height dimensions. You can also send us a photo of the old seal or the housing drawing. At MR Accesorios Industriales we cross-reference the designation with the alternatives available in the DBH line and in other brands we supply. That way we give you a compatible option without you having to guess.
