The DBH 5221 is a radial shaft seal that keeps lubricant in and contaminants out of equipment with a rotating shaft. With a 42 mm shaft, 65 mm housing and 12 mm height, it fits gear reducers, pumps, electric motors and power transmission components. MR Industrial Accessories LLC supplies it as part of its seals and oil seals line for maintenance and replacement.

This radial shaft seal carries the DBH brand and part number 5221. Its dimensions are shaft 42.00 mm, housing 65.00 mm and height 12.00 mm, with an Lx design. These measurements determine how the seal sits in the housing and where the lip rides on the shaft. Before installing a replacement, check the housing bore for burrs or scratches that could harm the new lip.

Seals in this size range appear in gear reducers and gearboxes, centrifugal pumps, electric motors, compressors and conveyor rollers. They also show up in agricultural and industrial machinery. Their job is to hold oil or grease in place while blocking dust, water and particles from getting inside.

When selecting a seal, look beyond the three dimensions at the lip type, material and rotation direction. The Lx design has a sealing lip and a profile that fits standard housings. During installation, coat the lip with the same lubricant used in the equipment, set the seal perpendicular and press it in with a tube or spacer that contacts only the outer ring, never the lip.

To get a quote for the 5221, send the dimensions of the old seal: shaft diameter, housing diameter and height. With that information we can find an 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 might be better.

For maintenance programs, consider ordering several sets and storing them in a dry place away from sunlight and ozone sources to prevent the elastomer from degrading before use.
