The DBH 5221 radial shaft seal is a lip seal that closes off lubricant and blocks dust, water or particles from entering equipment with a rotating shaft. Due to its dimensions —42 mm shaft, 65 mm housing and 12 mm height— it is fitted in reduction gear housings, pumps, electric motors and power transmission mechanisms. MR Accesorios Industriales supplies it as part of its line of seals and oil seals for maintenance and replacement.

This item is a radial shaft seal from the DBH brand, identified with part number 5221. Its dimensions are 42.00 mm shaft diameter, 65.00 mm housing diameter and 12.00 mm height, with an Lx design. This set of dimensions defines the mounting interference and the lip position on the shaft race. Before replacing, verify that the housing has no burrs or marks that could damage the new lip.

Seals of this size are used in equipment where a shaft rotates inside a housing with oil or grease. They appear in gear reducers and gearboxes, centrifugal pumps, electric motors, compressors and conveyor rollers. They are also found in agricultural and industrial machinery, where the main function is to retain lubricant and, at the same time, prevent contaminants from entering from outside.

To choose the right seal, in addition to the three dimensions you must look at the lip type, material and direction of rotation. The Lx design corresponds to a configuration with a sealing lip and a profile that adapts to standard housings. During installation, lubricate the lip with the same grease or oil as the equipment, seat the seal perpendicular and drive it into position with a tube or spacer that presses on the outer ring, never on the lip.

If part number 5221 is not available or you need an adjacent size, send us the dimensions of the old seal: shaft diameter, housing diameter and height. With that data we look for the equivalent in the same brand or another with similar performance. We can also advise you if the housing has a shoulder or if the shaft shows wear and an alternative solution is advisable.

To request a quote for the DBH 5221 oil seal, write to us on WhatsApp with part number 5221 or the dimensions 42 x 65 x 12 mm. From MR Accesorios Industriales we confirm alternatives within the seal line. If you run a maintenance program, it is advisable to order several sets and store them in a dry place, away from sunlight and ozone sources, so the elastomer does not degrade before use.
