A radial shaft seal that fits a 22 mm shaft inside a 37 mm bore with a 7 mm width, the DBH 5157 keeps lubricant where it belongs and keeps dust, water and particles out of the bearing cavity. The lip rides against the rotating shaft and flexes enough to absorb minor misalignment. Treat it as a wear item: once the assembly comes apart, a fresh seal goes in.

The DBH 5157 carries the part number 5157 and measures 22 mm at the shaft, 37 mm at the housing and 7.00 mm in height. Its A 135 configuration is a single lip with a spring, intended for rotating shafts under lubrication. Because the number is indexed in catalogs and ordering systems, the 5157 reference gets you to the right seal quickly. This is a sealing component, not a load-bearing one, so the fit between shaft and housing is what determines whether it works.

You will find a 22x37x7 mm seal in small gearboxes, electric motors, centrifugal pumps, compressors and transmission equipment. Machine tools, conveyors and agricultural machinery use it too, wherever a shaft turns inside a lubricated housing. In every case the seal holds oil or grease in and keeps dust away from the bearings. It suits assemblies where axial room is tight and a compact seal is the only option.

Before pressing one in, check the shaft for burrs or scratches that could cut the lip, and coat the lip with the same oil or grease the equipment runs on. Keep the seal square to the shaft and drive it with a tube of the right diameter rather than hitting the lip directly. If there is a shoulder in the housing, seat the seal against it. Peripheral speed, temperature and the fluid being retained all matter when you select. The A 135 design handles general duty at moderate speeds.

Looking for a cross to the DBH 5157? Search the 22x37x7 mm dimensions or the 5157 number under other brands. We can also quote a different size, such as one with the same shaft diameter but another height, or a slightly larger housing. For that, tell us the exact shaft and housing dimensions and which fluid you need to hold back.
