When a rotating shaft needs its lubricant kept in and outside contamination kept out, the DBH 5971 radial shaft seal is the replacement to look at. The Lz design uses a sealing lip backed by a spring, so contact on the shaft stays steady through continuous running. Its three key measurements are a 50.80 mm shaft, a 75.36 mm housing bore and a 7.93 mm height.
Reading the number is straightforward. DBH identifies the seal family, 5971 is the individual reference, and Lz describes how the lip is built: a spring-loaded element that presses against the shaft. The elastomer resists oils and greases, which keeps friction low and gives the seal a long working life.
You will find this size in gearboxes, pumps, electric motors, conveyor rollers and other power transmission equipment. It suits shafts turning at moderate speeds where lubricant is present, and it shows up in food, chemical and process plants where holding fluid in and keeping dust, water and particles out matters to the equipment.
Before fitting, confirm the shaft and housing bore match the figures above. Set the lip toward the lubricant, drive the seal in with a proper tool so the lip is not damaged, and put a little lubricant on the lip first. A shaft surface free of burrs helps. When choosing a seal, weigh the rotation speed, the operating temperature and how the elastomer reacts to the fluid being retained.
If you need the same dimensions in another configuration or a close variant, we can help. Give us the original part number, the shaft and housing sizes, and the working conditions, and our team will point you to a suitable option. Beyond seals, we supply bearings, mounted units and housings, power transmission parts, lubrication and maintenance tools.
