DBH 5871 radial shaft seal — 42 x 60 x 10

DBH 5871 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 5871 and any equivalents.

The DBH 5871 is a radial shaft seal that keeps lubricant in and contaminants out where a shaft turns inside a fixed housing. With a 42.00 mm shaft, 60.00 mm housing bore and 10.00 mm width, it fits medium-sized assemblies such as pumps, motors, gearboxes and rollers. MR supplies this brand and can help you confirm the size before you request a quote.

The 5871 code identifies one specific size in the DBH line: shaft 42.00 mm, housing 60.00 mm, width 10.00 mm. The Lz design means a sealing lip with a spring and a metal case, made for rotating shafts that run with lubrication. Before ordering, compare these figures with the old seal or measure the shaft and housing with a caliper. If either surface is worn, the lip will not seat properly and oil will find its way out.

Seals in this size range show up in centrifugal pumps, electric motors, gearboxes, mixers and other power transmission equipment. You will also find them in agricultural machinery, compressors and roller systems where oil has to stay separated from the environment. In every case the lip rides on the rotating shaft while the outer diameter stays fixed in the housing. In dirty or wet conditions, it is worth looking at a version with an extra dust lip.

Installation starts with a clean housing and shaft, free of burrs and wear marks. Lubricate the lip with the same oil or grease used in the equipment, then press the seal in squarely using a tube or spacer that contacts only the outer diameter. With a width of just 10.00 mm there is little room to spare: if the housing has a shoulder, the seal must seat completely and without tilting. Check the internal spring and make sure the lip is not facing the wrong way.

If you need an alternative, send us the 5871 code together with the shaft, housing and width measurements. A photo of the old seal or the equipment drawing works too. With that information we search the DBH line and other compatible options, always keeping the Lz design or the correct lip type for your assembly. The code does not have to match exactly; what matters is that the three dimensions and the lip style fit the application.

MR carries DBH as part of its seals and oil seals range. If you already have the 5871 number, message us and we will confirm the size and send a quote. If the seal is still installed and you cannot read the number, send the measurements taken with a caliper and a photo of the housing. That way we avoid errors and point you to the option that suits your equipment.
