The DBH 5271 is a radial shaft seal from the DBH line, built to hold lubricant in and keep contaminants out where a shaft turns inside a fixed housing. Its 25 mm shaft, 40 mm housing and 10 mm height suit compact gearboxes, pumps and electric motors. MR Industrial Accessories supplies this brand and helps you select the right seal for your application.
This seal carries the part number 5271 in the DBH line. The dimensions are shaft 25 mm, housing 40 mm, height 10 mm. The Lz design means a single lip with a spring, which is used where axial space is tight and dependable sealing against oil or grease leaks is needed.
You will find radial shaft seals like the DBH 5271 wherever a shaft rotates inside a stationary housing: gearboxes, centrifugal pumps, electric motors, compressors, mixers, and belt or chain drives. They do two jobs: stop lubricant from escaping and block dust, water or particles that speed up wear on bearings and gears. In plants, they show up in process lines, pumping equipment and motion machinery.
When installing an oil seal, check the shaft for burrs or deep marks, lubricate the lip before pressing it in, and seat it square to the shaft. Selection depends on rotation speed, working temperature, lubricant type and differential pressure. If the original seal has a different design, compare the lip profile and elastomer material, because a dimensional match does not always mean the same service performance.
To get a quote, send the full part number stamped on the seal or the shaft, housing and height dimensions. With that information we can look for an alternative in the same category or suggest a seal with similar characteristics. We can also advise on the elastomer and spring type based on your equipment's fluid and temperature.
