The DBH 5878 is a radial shaft lip seal built to hold lubricant in place and block contaminants from reaching rotating parts. Its measurements are shaft 50.00 mm, housing 67.00 mm and height 11.00 mm, in the Lz design. It belongs to the seals and oil seals line we supply to maintenance and purchasing teams.

The code breaks down simply: DBH is the seal family, 5878 is the item reference, and the three figures describe where it sits. The 50.00 mm value is the shaft diameter (d), 67.00 mm is the housing bore (D), and 11.00 mm is the height (h). In the Lz design, a spring keeps the sealing lip pressed against the shaft so contact stays constant while the equipment turns. The elastomer compound resists wear and the oils and greases normally found in machinery.

Where you will see it working: gearbox and transmission shafts, bearing positions, centrifugal pumps, compressors, mixers and other process equipment. Its job is twofold, keeping lubricant where it belongs and keeping dust, water and particles out of the bearing cavity. The Lz configuration suits medium speeds and tougher duty. Industrial, automotive and agricultural maintenance crews are the usual users.

Before ordering, confirm that the shaft and housing on your unit match these figures. The shaft must sit inside the recommended tolerance so the lip seats correctly, and the 11 mm height has to clear the mounting space without interference. Fit the seal with the lip pre-lubricated using the same oil or grease as the machine, keep sharp edges away from the lip, and make sure the bore is clean and free of burrs. For high-speed duty, ask about alternative designs.

If you need the same dimensions from another line or a close variant, send the original code plus the shaft, housing and height measurements and describe the application. We can point you to a suitable design for your operating conditions. Quotes are handled by WhatsApp or email using the part number, and the team can suggest equivalents and help with selection.
