The DBH 8761 is a radial shaft seal with a single lip and spring, sized for a 38 mm shaft, a 48 mm housing bore and a 4 mm width. It keeps lubricant in and contaminants out of rotating equipment such as gearboxes, pumps and electric motors. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your application.

This seal carries the designation 8761 and the Ms code, which indicates a single lip with a spring. The lip runs against the shaft while the outer case presses into the housing. Its role is to hold oil or grease inside and block dust, water and particles from reaching bearings and gears. It is a small, low-cost component, but its condition directly affects how cleanly and continuously a machine runs.

You will find this size in gearboxes, centrifugal pumps, electric motors, compressors and belt or chain drives. It also appears in machine tools, industrial washing equipment and material handling systems. In every case, the seal protects the lubricant and the bearing environment. When it fails, leaks and contamination follow, so replacing it on schedule is part of normal maintenance.

Before installation, make sure the shaft is clean and free of burrs or marks, and lubricate the lip. The housing bore should be ground and undamaged. Because the 4 mm width is narrow, use a proper installation tube to avoid deforming the seal. If the shaft shows wear, a seal with the lip in a different position may be an option. Speed, temperature and lubricant type also influence selection, so ask if you are unsure.
