When a rotating shaft needs its lubricant kept in and contaminants kept out, the DBH 1275 oil seal is the part to look at. It is a single-lip radial shaft seal built in the A 422 design, which pairs a sealing lip with an outer dust lip on a metal case. That combination suits equipment running in dusty or particle-heavy surroundings. MR Industrial Accessories supplies this brand and can help you confirm the size before you order.

Reading the code is the fastest way to check fit. The DBH 1275 carries a 16 mm shaft diameter, a 23.5 mm housing diameter and a 30 mm height. That 30 mm height tells you this is a wide-section seal, so it belongs in a deep housing or in a spot where the gap between shaft and housing is larger than usual. The A 422 layout means the main lip does the sealing while the dust lip sits outboard and takes the first hit from grit and dirt, which keeps the sealing lip cleaner in service.

You will find this seal on gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. Agricultural machinery, construction equipment and hydraulic systems use it too, anywhere lubricant has to stay put and dust has to stay out. Because of the double-lip construction, it holds up in mills, mixers and material conveyors where particles are always present. It is a common item on preventive maintenance lists, so keeping the dimensions on hand helps when a replacement is needed.

Before ordering, match all three dimensions to the original housing: shaft, housing bore and height. The shaft surface should be ground and hard enough to keep the lip from wearing early. Lubricate the lip with the same oil or grease the equipment runs on, and use an installation tool so the lip is not damaged on the way in. Set the seal perpendicular to the shaft and press it until it seats fully at the bottom of the housing. If the shaft has splines or burrs, clean them up first.
