The DBH 8977 is a radial shaft seal that fits into a housing and runs against a rotating shaft to keep lubricant in and contaminants out. It measures 85.00 mm at the shaft, 110.00 mm at the housing and 12.00 mm in height, and its Lx design denotes a single lip with a spring. This size is common in industrial machinery, and MR Industrial Accessories LLC supplies it for repair and maintenance work.
This seal carries the DBH brand and part number 8977. In the Lx configuration, a single lip with a spring contacts the shaft, making it suitable for rotating equipment that uses oil or grease. The seal is pressed into a machined housing cavity, where the lip rides directly on the shaft to form the sealing line.
You will find it in gearboxes, pumps, electric motors, rollers, mixers and transmission equipment, wherever a shaft turns inside a housing and lubricant must be retained. In dusty or splash-prone areas, the lip also helps keep particles and moisture away from bearings and gears.
During installation, confirm that the shaft is within tolerance and free of burrs, and that the housing bore and depth match the seal. Apply lubricant to the lip, then press the seal in squarely, without uneven blows. If the shaft already shows a wear track, repositioning the lip or using a seal with a different lip location can help avoid a repeat failure.
For an equivalent, provide part number 8977 with the shaft, housing and height dimensions, plus a description of the application. Our team can search for a compatible seal from the same brand or another brand we supply, and we verify the technical data before quoting. We can also advise whether a different height is feasible in your space.
