The DBH 5321 is a radial shaft seal built for rotating shafts, where its job is to hold lubricant in and keep dust, water and particles out. With an Lx single-lip design, it fits a 17 mm shaft, a 32 mm housing bore and a 9.00 mm height, which places it among the common sizes used on gearboxes, pumps, motors and transmission assemblies. MR Industrial Accessories LLC supplies this brand and helps you match the right seal to the application.

Reading the reference is straightforward: 5321 is the designation, and the size follows the shaft-housing-height order, so you are looking at shaft 17 mm, housing 32 mm, width 9.00 mm. The Lx configuration means one sealing lip with a spring, a layout intended for lubricated rotating shafts. It belongs to the line of seals and oil seals we carry for industrial maintenance and replacement work.

Seals in this size range show up on gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In each case the function is the same: keep oil or grease where it belongs and stop outside contamination from reaching the bearing. Machine tools, conveyors and agro-industrial equipment running at moderate shaft speeds in dusty or damp conditions are also typical homes for this seal.

Before fitting, confirm that the shaft and housing bore match the stated dimensions. Lubricate the lip, then press the seal in with an installation tube so the sealing edge is not nicked or rolled. Shaft condition matters as much as the seal itself: runout, surface finish, scratches and burrs all speed up lip wear. Where vibration or temperature runs high, look at a lip material better suited to those conditions.

Need a cross-reference? Send code 5321 along with your shaft, housing and height measurements, or a photo of the worn seal or the assembly drawing. We check that data against the alternatives we supply and come back with the option that fits without giving up sealing performance or housing tolerance.
