The DBH 8218Vit is a radial shaft seal built to keep lubricant where it belongs and keep contaminants out of rotating equipment. With a 57 mm shaft, a 77 mm housing bore and a 10 mm height, it fits common gearbox, pump and transmission arrangements. MR Industrial Accessories supplies this brand and helps you confirm the right seal before you order.

Reading the designation helps in selection. The code 8218Vit identifies this seal, and the three figures that follow describe the fit: 57 mm at the shaft, 77 mm at the housing bore, 10 mm in height. The Lx-RAH configuration uses two lips, one that retains lubricant and one that keeps dust out. The elastomer lip runs against the rotating shaft while the outer diameter seats in the housing bore to close the gap.

You will find this seal on gearboxes, centrifugal pumps, electric motors, conveyor rollers and other power transmission equipment. Its job is straightforward: hold oil or grease in, and block abrasive particles that would otherwise shorten the life of bearings and gears. Treat it as a wear item and replace it on a preventive maintenance schedule rather than waiting for a leak.

Installation quality decides how long the seal lasts. Check the shaft for burrs or deep marks and make sure the sealing surface is polished before you start. Coat the lip with the same oil or grease used in the equipment, then press the seal in with a proper mounting tube so the lip is not damaged. When selecting a replacement, account for shaft speed, operating temperature and the fluid involved. If your original seal carries a different designation, an equivalent size in the DBH line may cover it.

To get a quote, send the full code marked on the seal along with the shaft, housing and height dimensions, plus a photo if you have one. From that information we quote the DBH line and can suggest compatible alternatives. We can also help you decide whether a design with or without a dust lip suits your contamination level.
