Part number 8250 is a DBH radial shaft seal whose lip rides against a rotating shaft to hold lubricant in and keep dirt out. Its three key measurements are a 27 mm shaft, a 42.82 mm housing bore and a 6.35 mm width, so it fits assemblies where axial room is tight. The Lz configuration pairs a primary sealing lip with a secondary lip that acts as a barrier against particles, which helps in dusty or dirty service. Gearboxes, pumps, motors and reducers are among the places this seal is commonly found.

Reading the code and the dimensions: 8250 identifies the seal, while the size string follows the usual order of shaft diameter, housing diameter and height. Here that means shaft 27 mm, housing 42.82 mm, width 6.35 mm. The Lz designation tells you the seal carries both a main lip that contacts the shaft and an auxiliary exclusion lip. The elastomer lip is meant to run against the shaft surface and keep the lubricant where it belongs.

Where it is used: gearboxes, centrifugal pumps, electric motors, gear reducers and transmission equipment. You will also find this type of seal in agricultural machinery, construction equipment and hydraulic systems, wherever oil or grease has to stay inside and contamination has to stay outside. Because it is compact, it suits housings with limited mounting space, as long as the operating conditions match the seal material.

Selection and installation checks: confirm that the shaft and housing measurements match the values above before ordering. A ground shaft with sufficient hardness helps limit lip wear. Lubricate the lip before pressing the seal in, keep it square to the shaft, and avoid hitting the sealing element during installation. For high speed or high temperature service, contact MR Industrial Accessories to review a more suitable option.
