Part number 9537 belongs to the DBH seal range. This radial shaft seal runs against a 27 mm shaft and seats in a 76 mm bore, with a height listed as 16.00/13.50 mm and lip geometry identified as design A 228. Its job on the machine is straightforward: hold the oil or grease on the inside of the assembly and keep dust, water and other particles on the outside, so bearings, bushings and gears are not exposed to them. Gearboxes, pumps, motors and other rotating equipment are the usual homes for a seal of this size.

Reading the size callout helps you match the part to the bore. The 27 mm figure is the shaft diameter the lip contacts, the 76 mm figure is the housing bore, and the two heights, 16.00 mm and 13.50 mm, reflect that the lip section and the outer body of the seal sit at different levels in the housing. Design A 228 covers the shape of the lip and how the internal spring is arranged. DBH is one of the seal lines MR supplies, so the part can be traced back to its manufacturer.

You will typically find this seal on gearboxes, centrifugal pumps, electric motors, compressors, and belt or chain driven equipment. In every case the seal works between a turning shaft and a stationary housing, keeping the lubricant separate from the surrounding environment. Machine tools, lifting equipment and conveying systems also use seals in this size range, particularly where dust or metal chips would otherwise reach the bearings.

Installation is where most seals are lost. Confirm the shaft is free of burrs, scratches and grooves that could damage the lip, and check that its hardness and finish suit the application. Coat the lip with the same oil or grease the equipment uses, then press the seal in squarely to the shaft rather than hammering on the face. If the bore is worn or deeper than expected, a taller design may be the better choice. Speed, temperature and the fluid being retained all influence which seal is correct.

If you send us part number 9537 or simply your shaft, housing and height measurements, we can look through the DBH line and the other brands we carry for a match. We will also tell you when a worn shaft or an unusual bore depth means a different option makes more sense, so the decision is confirmed before you commit. Quotes are handled by WhatsApp or email, and we answer with the part that fits your dimensions.
