DBH 8971 belongs to radial shaft seal, part of our Seals range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 8971 and any equivalents.

The DBH 8971 is a radial shaft seal that sits in the housing and seals against the rotating shaft, keeping lubricant in and contaminants out. It measures 70 mm at the shaft, 110 mm at the housing and 8.00 mm in height, and uses the Lx design. You will find it in gearboxes, pumps, motors and transmission equipment where bearings need protection and oil must stay inside.

This seal belongs to the DBH line and is identified by part number 8971. Its dimensions are: shaft 70 mm, housing 110 mm, height 8.00 mm. The Lx design is a single-lip seal with a spring, made for rotating shafts with internal lubrication. The elastomeric lip presses against the shaft while the outer case holds the fit in the housing. As a wear part, it will eventually harden or mark and begin to lose oil.

Seals of these dimensions are common in gearboxes, speed reducers, centrifugal pumps, electric motors and power transmission equipment. They also appear in machine tools, mixers and conveyors where a shaft turns inside an oil-filled housing. The job is always the same: stop lubricant from escaping and keep dust, water and particles away from the bearing or gear.

During installation, check that the shaft is within tolerance and free of burrs, and that the housing bore has no dents or rust where the seal seats. Lubricate the lip before pressing it in, and keep the seal perpendicular to the shaft. Use a tube or spacer that pushes on the outer edge, never on the lip. If the shaft shows wear, a seal with an offset lip may be worth considering. The right choice also depends on the lubricant, temperature and rotation speed.

For an equivalent or a different size, send part number 8971 with the shaft, housing and height dimensions, plus the type of equipment it fits. A photo of the old seal or the seat helps too. With that information we can look for the replacement in the DBH line and quote it. If the Lx design does not suit your application, we will review it with you.
