The DBH 1210 is a radial shaft seal with a single lip and spring, sized for a 35 mm shaft, 52 mm housing bore and 12 mm width. It keeps oil or grease in and dirt or water out of rotating assemblies such as gearboxes and pumps. As a wear part, it starts leaking when the lip hardens or the spring weakens. MR Industrial Accessories supplies this brand and can help you match the right replacement.

This seal carries the designation 1210 and the Lx design, meaning one sealing lip with a spring for rotating shafts with internal lubrication. The dimensions to check are shaft 35 mm, housing 52 mm and height 12.00 mm. It presses into a cylindrical housing and the lip runs against the shaft surface. The brand is one MR supplies, so the replacement maintains the original geometry and material.

You will find this seal in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. It also appears on fan shafts, mixers and agricultural or process machinery. In every case its job is twofold: retain the lubricant and keep particles away from nearby bearings or bushings.

Proper installation starts with the shaft. Remove burrs, deep scratches or worn spots in the contact area, because a damaged shaft will ruin the lip quickly. Coat the lip with the same oil or grease used in the equipment, then press the seal in squarely without hitting the lip. If the housing is corroded or loose, fix that first. When selecting a seal, respect the shaft, housing and height dimensions, and choose the lip material based on temperature and the fluid being sealed.

For an equivalent, send the code 1210 with your shaft, housing and height measurements. It also helps to include the fluid type, working temperature and shaft speed. With that information we can search the DBH line or another compatible option. If space permits, a seal with an extra lip or a different material can be considered, as long as the mounting dimensions stay within the housing tolerance.

Before replacing, inspect the shaft and housing. A new seal on a worn surface will not seal. If you are unsure about lip orientation or rotation direction, ask us.
