The DBH 6763Sil is a radial shaft seal built to hold lubricant in and keep contaminants out where a shaft turns. With a 54 mm shaft, an 81.10 mm housing bore and a 21 mm height, it fits medium-sized power transmission assemblies where radial room is tight and the closure has to be dependable. The seal is pressed into the housing and its lip rides on the shaft surface. MR Industrial Accessories supplies it within its seals and radial shaft seal range.

The reference 6763Sil comes from the DBH line. Reading the size: shaft 54 mm (d), housing 81.10 mm (D), height 21.00 mm (h). The A 102 design is a single-lip, spring-loaded version intended for rotating shafts that run with lubrication. A lip elastomer bonded to an outer metal case makes up the unit, which is press-fitted into the housing cavity and bears against the shaft.

Seals in this size range turn up in gearboxes, centrifugal pumps, electric motors, rollers, and belt or chain drives. Their job is twofold: no oil or grease escapes, and no dust, water or particles get in to wear bearings and gears faster. That makes it a common replacement item in plant preventive maintenance schedules.

Selection starts with three checks: shaft diameter, housing bore and the height available. The shaft should be ground, with no splines or burrs, and the housing clean and undistorted. At installation, coat the lip with the same oil the equipment uses and drive the seal with a support tube so the lip is not damaged. If the shaft is worn, a repair sleeve or a seal positioned with the lip on a different track may be the answer.

For a quote, send the equipment data or your caliper readings: shaft diameter, housing diameter and height, and note any equivalent from another brand. With those figures we can search for an alternative in the DBH line or in other brands we carry. We can also tell you whether the A 102 design suits your application or whether a different lip arrangement is needed.
