Part number 5776 is a radial shaft seal from DBH, built to hold lubricant in place and keep contaminants out of rotating assemblies. Maintenance and purchasing teams specify it by its three key measurements: shaft 42.86 mm, housing 70.20 mm, width 6.35 mm. Those dimensions suit equipment where the seal seat is narrow. MR Industrial Accessories supplies this brand and helps you match the seal to your application.

The 5776 belongs to the DBH line of oil seals. The Lt designation describes how the seal is put together: a sealing lip combined with a metal case. That construction is common on rotating shafts that need oil or grease retained, and the elastomer compounds together with the metal reinforcement are chosen to hold up under continuous duty. When you read the code, treat 5776 as the reference number and the three figures as shaft, housing and width, in that order.

You will find seals like this in centrifugal pumps, electric motors, gear reducer boxes, compressors and power transmission equipment. In each case the seal keeps lubricant where it belongs and blocks dust, water and particles from reaching the interior. Because bearings and gears depend on that barrier, a worn seal is a maintenance item worth tracking: a failure can take a machine offline without warning and lead to more serious damage.

Proper installation protects the lip. Confirm the shaft and housing bore are clean and free of burrs or scratches, then coat the lip with the same oil or grease the application uses. Press the seal in squarely to the shaft, using an installation tube sized for the job so the lip is not distorted. If the shaft surface shows wear, a repair sleeve or a different size may be the better route to a dependable seal.
