The DBH 5151 is a radial shaft seal built to hold lubricant in place and keep dust, water and particles out of rotating equipment. It measures 38 mm at the shaft, 52 mm at the housing and 8.00 mm in height, and it carries the Lx design. Pumps, electric motors, gearboxes and transmissions are the usual homes for this kind of wear part. MR Industrial Accessories supplies the DBH line and can help you match the seal to your application.

The 5151 designation places this seal within the DBH range, and its Lx design points to a standard lip and case arrangement for lubricated rotating shafts. Fit is defined by three values: shaft 38 mm, housing 52 mm, height 8.00 mm. The seal sits on the shaft and inside a machined cavity, so those three figures are what you confirm before anything else.

You will find this seal in centrifugal pumps, electric motors, gearboxes, conveyor rollers and belt or chain drives. In each case it shields the bearings and the lubricant from what is happening outside the housing. Process equipment, industrial washing machines and agricultural machinery also use it. Shaft and housing condition matter: marks or wear on either surface shorten the life of a new seal, so inspect both before installing.

Installation starts with a clean shaft and housing, free of burrs and scratches, and a lip lubricated with the same oil or grease used in service. Press the seal in squarely, using a tube or press that bears on the metal case rather than the lip. Shaft speed, temperature, lubricant type and differential pressure all influence which seal is right. Where dirt is heavy, a version with an auxiliary lip or dust guard is worth considering. The shaft, housing and height dimensions stay as specified.

If you are after an equivalent, send the code 5151 or the measurements of the seal you are replacing, meaning shaft diameter, housing diameter and height. You can also ask about other brands or seals with special features such as a double lip or high-temperature materials. The team helps you identify the part that fits your equipment.
