The DBH 8918 is a radial shaft seal with an Lx design, built to keep lubricant in and contaminants out of rotating equipment. It fits a 45.00 mm shaft, a 70.00 mm housing and has an 8.00 mm height. The lip is backed by a spring for continuous contact, and the outer metal case presses into the housing. MR Industrial Accessories supplies this seal and can help you match it to your application.

This seal is identified by part number 8918 under the DBH brand. Its dimensions are shaft 45.00 mm, housing 70.00 mm, height 8.00 mm. The Lx configuration uses a sealing lip with a spring that maintains pressure on the shaft. The elastomer resists oils and greases, while the metal outer structure allows a firm press fit. It protects bearings and other components from lubricant loss and outside contamination.

You will find this seal in gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. It also appears in agricultural machinery, conveyors and hydraulic systems that rely on dependable sealing at rotating shafts. By holding lubricant in place and blocking dust, it helps extend bearing life and reduce unplanned downtime. It is a standard choice for 45 mm shafts turning at moderate to high speeds.

Before installation, confirm that the shaft and housing match the seal dimensions. Clean the shaft and remove any burrs or marks, then lubricate it before sliding the seal on. The housing should have an entry chamfer to protect the lip. Use an installation tool that applies even pressure on the outer ring. For high speed or high temperature operation, select a suitable lip material. Contact our team if you are unsure.

If you need a replacement, send part number 8918 or the shaft and housing dimensions. MR Industrial Accessories can source equivalents from other brands and help identify the right seal from a sample or your measurements. We also advise on special materials for specific applications.
