DBH 6857 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 6857 and any equivalents.

A radial shaft seal from the DBH line, reference 6857, sized for a 70 mm shaft, a 115 mm housing bore and a 15.00 mm height. Its Lx configuration uses a single lip with a spring, so the sealing edge rides on the rotating shaft while the outer case stays pressed into the housing. That arrangement holds oil or grease inside the assembly and keeps dust, water and particles out. This is a widely used size in pumps and power transmission equipment, and we supply it within our seals and oil seals range.

Reading the code helps when you reorder. The 6857 identifies the DBH item, and the Lx suffix tells you the lip style: one sealing lip, spring loaded, meant for a rotating shaft. The three figures to match against your equipment are shaft 70 mm, housing 115 mm and height 15.00 mm. If any of those differs, the seal will not seat or seal correctly.

You will find this size in gearboxes, centrifugal pumps, electric motors, conveyor rollers and similar transmission assemblies. Its job is to keep lubricant where it belongs and to stop outside contamination from reaching bearings and gears. Because the lip runs against the shaft continuously, the seal wears over time and is normally replaced as a maintenance item once leaking or unusual noise appears at the sealing point.

Before ordering, confirm the shaft and housing measurements and check the shaft surface. It should be ground, free of splines and hard enough that the lip is not damaged in service. Fit the seal squarely to the shaft, coat the lip with the same lubricant used in the machine, and press it in without hammering on the sealing edge. Where the housing bore is worn, an oversized-case seal or a repair sleeve is worth considering.

If you need something that works in place of the 6857, send us the reference or the three dimensions and we will review alternatives in other brands or lip configurations, keeping the shaft, housing and height the same. We can also help you settle on the right lip design for your speed, temperature and lubricant. Separately, our own manufacturing covers EMMAR housings, chains and sheaves.

Quotes are handled by part number: message us the code 6857 or the size 70 x 115 x 15 mm and our team will come back to you with the options. If you are unsure whether this is the right seal for your unit, describe the application and we will help you confirm it.
