The DBH 5084 radial shaft seal keeps lubricant in and contaminants out on rotating equipment. It fits a 20 mm shaft, a 40 mm housing bore and a 10 mm width, and its Lx design uses a single lip with a spring. You will find it in gearboxes, pumps, motors and similar transmission assemblies, where it shields bearings and gears from dust, water and wear particles.

This seal carries the DBH brand and part number 5084. The data sheet lists a 20 mm shaft diameter, a 40 mm housing diameter and a 10 mm height. The Lx designation points to a spring-loaded single lip that holds oil or grease in moderate rotation service. The elastomeric lip rides against the shaft while the outer diameter presses into the housing bore to close the gap.

Seals of this size appear in gear reducers, centrifugal pumps, electric motors, speed reducers and power transmission drives. They also turn up on fan shafts, mixers and continuous process lines. In every case the job is the same: stop lubricant from escaping and block dust, water or particles that would otherwise shorten bearing and gear life.

Before fitting the seal, confirm a 20 mm shaft and a 40 mm housing bore, and check that the housing width matches the 10 mm height. The shaft surface should be clean and free of burrs, scratches or heavy wear, since a rough shaft speeds up lip damage. Coat the lip with lubricant, press the seal in squarely and avoid hitting it directly. For high peripheral speeds or hot running conditions, ask us about the lip material.

If you need a replacement or an equivalent, send the part number 5084 or the three key dimensions: shaft, housing and height. We can search within the DBH range and the other brands we supply, keeping the same lip type and design. We can also tell you whether a different height will seat in your housing or whether a dust lip version makes more sense.
