When a rotating shaft needs its lubricant kept in and outside contamination kept out, a radial lip seal like the DBH 6287 does the job. Its three governing dimensions are shaft 25.4 mm, housing 41.25 mm and height 7.54 mm, and its Ls design covers moderate-speed, low-pressure duties in gearboxes, pumps, motors and transmission assemblies.

Reading the designation helps you avoid a wrong fit. The 6287 number pins down one specific size in the DBH line, while the Ls code describes a radial shaft seal with a single sealing lip in an elastomer that stands up to oils and greases. Before you pull a worn seal, confirm the three measurements on the actual hardware: shaft 25.4 mm, housing 41.25 mm, height 7.54 mm. A small deviation in any of them is enough to cause weeping or early failure.

These seals turn up in gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In each case the lip retains lubricant and blocks dust, water and particles, which keeps the bearings running clean and protects the assembly over time. That makes the seal a routine item on any preventive maintenance schedule.

Selection goes beyond the three dimensions. Rotation speed, operating temperature and the lubricant in use all affect how long the lip lasts, and the Ls design suits moderate speeds with low pressure. During installation, keep the lip free of nicks and lubricate the edge before pressing it in. If the shaft surface is scored, look at an auxiliary lip or a wear sleeve instead of a plain replacement.
