The DBH 1249 is a radial shaft seal featuring a single lip with a spring. It measures 33 mm at the shaft, 55 mm at the housing and 8.50/13.50 mm in height. This seal keeps lubricant in and contaminants out of rotating equipment. MR Industrial Accessories supplies this brand and helps you match the right seal to your application.

This DBH 1249 seal uses the A 308-R H design, which means a spring-loaded sealing lip for reliable performance under rotation. The stepped height of 8.50/13.50 mm lets it seat firmly in housings that have a shoulder. It serves as a direct replacement wherever oil or grease retention and protection from dust and water are required.

You will find these seals in gearboxes, centrifugal pumps, electric motors, compressors and belt or chain drive systems. In those machines, the seal stops lubricant from escaping and blocks particles that would otherwise speed up wear on bearings and gears. Agricultural machinery, construction equipment and process lines also rely on them to avoid unexpected downtime.

Before installation, check that the shaft surface is hard and smooth enough, with no burrs or scratches. Coat the lip with the same oil or grease used in the equipment. Set the seal perpendicular to the shaft, either flush with the housing or slightly recessed as the design calls for. Do not strike the lip while pressing it in. If the shaft is worn, a repair sleeve or a different size may be the better option.

When you need a cross-reference, send the complete part number, the shaft, housing and height dimensions, and a photo of the seal. With those details we can search our seals and oil seals line for a compatible alternative. We can also guide you on lip type, material and spring based on the temperature and speed of your equipment.
