The DBH 6276 radial shaft seal is a lip seal designed to close off the passage of oil or grease at the point where a shaft passes through a housing. Its Mz design combines a sealing lip with a metal body that is press-fitted into the housing, so that lubricant stays inside and dirt stays outside. It is used in gearboxes, pumps, electric motors and transmission equipment where the shaft rotates continuously.

This seal is identified by its designation 6276 and by the dimensions that define its installation: shaft diameter of 22.22 mm, housing diameter of 52 mm and height of 10.00 mm. Design Mz corresponds to a single-lip configuration with a metal case, suitable for rotating shafts with permanent lubrication. Before replacing a seal, it is advisable to check that these three dimensions match the machine's housing and shaft, because a difference of tenths prevents correct seating.

Typical applications for a seal of this size appear in equipment with small-section shafts and moderate speeds: gearboxes, centrifugal pumps, electric motors, mixers, conveyors and machine tools. In all these cases it performs the same function: retaining lubricant inside the assembly and preventing dust, chips or water from entering. It is also found in agricultural equipment and in process lines where the shaft passes from a lubricated enclosure to an exposed one.

To select and install a radial shaft seal, check the condition of the shaft: if it shows wear, scratches or a marked track, the new lip will not seal properly and it is advisable to consider a repair sleeve or an alternative size. The housing must be clean, free of burrs and deep enough to accommodate the 10.00 mm height. When installing it, lubricate the lip, seat the seal squarely and press evenly, without striking the lip or deforming the case.

If you need an equivalent seal or a neighboring size, the most practical approach is to send part number 6276 together with the shaft and housing dimensions, or directly the drawing or photo of the old part. With that data, an alternative from the same brand or from another brand that MR sells can be found, always respecting the mounting dimensions. If the shaft is worn, a seal with an offset lip or a different shaft size can also be considered.

DBH is a brand that MR sells, and this seal is available to order along with the rest of the seals and shaft seal line. To move forward with the quote, send part number 6276 on WhatsApp to MR Accesorios Industriales and the team will confirm the size and the alternative. If you are unsure between two sizes, attach the shaft and housing dimensions and they will be compared against the manufacturer's data sheet.
