The DBH 5877 is a single-lip radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. With a 44.45 mm shaft diameter, 66.68 mm housing bore and 7.93 mm height, it fits gearboxes, pumps, electric motors and transmission drives. MR Industrial Accessories supplies this seal and can help you confirm the right choice for your application.
This seal carries the DBH 5877 code and the 5877 designation with an Lx design. The Lx design denotes a single sealing lip, which suits installations where axial space is tight and a reliable barrier against oil or grease loss is required. The lip runs against the shaft while the outer case seats in the housing bore with an interference fit.
You will typically find a seal of these dimensions in gearboxes, centrifugal pumps, electric motors, compressors and belt- or chain-driven transmission equipment. In each case it shields bearings and gears from dust and water while holding lubricant in place. As a wear part, it should be replaced whenever a leak appears or when the machine is opened for a major repair.
Before mounting, check the shaft for burrs or wear and make sure the housing bore is clean and undistorted. Apply the same oil or grease used in the application to the lip, then press the seal in. The 7.93 mm height must match the housing depth so the seal sits flush or slightly recessed. If the shaft shows a wear track, you can reposition the lip or use a repair sleeve.
For an equivalent to the DBH 5877, send the complete code, the shaft, housing and height dimensions, and a photo of the old seal. With that information we can search our seals line for a compatible option. We can also review lip type, material and operating temperature and speed to make sure the selection is correct.
