The DBH 8570Sil is a radial shaft seal that sits in the housing bore and rides on the rotating shaft, holding lubricant in and keeping dust, water and particles out. Its published dimensions are 76 mm for the shaft, 98 mm for the housing bore and 12.00 mm for the height, and it carries the Lx-R-H design. MR Industrial Accessories supplies it within its seals and oil seals range for industrial maintenance work.

This seal comes from the DBH brand and is listed under part number 8570Sil. Reading the size code: shaft side 76 mm (d), housing bore 98 mm (D), overall height 12.00 mm (h). The Lx-R-H designation describes the build, which combines a sealing lip, a reinforced outer body and a secondary lip for exclusion. Oil or grease service on a continuous duty basis is what this configuration is intended for. The outer case seats in the housing while the lip contacts the shaft, which is how the barrier against leakage is formed.

Gearboxes, reducers, centrifugal pumps, electric motors, rollers and power transmission equipment are the usual places this oil seal turns up. In those assemblies it keeps bearings and gears clear of outside contamination and stops lubricant from escaping. Machine tools, process equipment and conveyor systems with a constantly turning shaft also rely on this type of seal, since the working life of the assembly depends on it.

Before fitting, confirm the shaft measures 76 mm and the bore 98 mm, and check both surfaces for burrs or marks that could cut the lip. Coat the lip with the same oil or grease the equipment runs on, then drive the seal in with a tube that bears on the outer diameter only, never on the lip. Depending on how the housing is made, the 12.00 mm height should end up flush or slightly recessed. A repair sleeve is worth considering where the shaft shows wear.

If you are after an oil seal equivalent to the 8570Sil, send the part number, the shaft, housing and height dimensions, and a photo of the old seal or the housing bore. We use that information to search the same series and other brands we carry. We can also point you toward the lip design that fits your lubricant, speed and site conditions.
