DBH 8101Pol radial shaft seal — 120 x 140 x 13

DBH 8101Pol 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 8101Pol and any equivalents.

The DBH 8101Pol is a radial shaft seal built to the Mx pattern, a single-lip design with a spring that sits in the housing and rides on the shaft. It holds lubricant in place and keeps dust, water and particles out. The size covered here is a 120 mm shaft, a 140 mm housing bore and a 13 mm height, a combination found in many continuously rotating industrial drives. MR supplies this seal as part of its seals and oil seals range.

Reading the code and the size is the fastest way to confirm a match. The designation DBH 8101Pol identifies the seal, while the three figures that matter on the drawing are shaft (d) 120 mm, housing (D) 140 mm and height (h) 13.00 mm. The Mx configuration means one sealing lip with a spring, intended for rotating shafts that run with lubrication. Shaft and housing diameters decide whether the part will fit; the height tells you how much axial room the seal occupies.

Seals in this size range turn up in gearboxes, pumps, electric motors, rollers and other power transmission equipment where a shaft rotates inside a stationary housing. You will also find them on conveyors, agricultural implements and centralized lubrication systems. Whatever the machine, the job is the same: retain oil or grease and block the contaminants that shorten bearing and gear life.

Installation calls for a clean, burr-free shaft in the lip contact zone, a light film of lubricant on the lip before it goes in, and a seal seated square to the shaft. Where the housing has a shoulder or radius, a guide sleeve helps the lip pass without damage. When selecting a replacement, confirm shaft diameter, housing diameter, height and lip style, and take rotation speed and operating temperature into account.

If you are cross-referencing, send the part number 8101Pol or the three dimensions of the seal you are replacing by WhatsApp. We can trace the matching DBH reference or review options in the same seals category. Details such as the equipment type, the lubricant used and the service conditions let us narrow the proposal.

MR carries the DBH brand within its seals and oil seals catalog. If you already have the number 8101Pol or simply need to verify a size, message us on WhatsApp and we will come back with the technical data. We can also walk you through mounting and care so the seal performs as expected.
