The DBH 6921 is a radial shaft seal built to keep lubricant in and contaminants out of equipment with a rotating shaft. Its size — 108.05 mm shaft, 142.88 mm housing, 13.00 mm height — places it in gearboxes, pumps and medium-to-large power transmissions. MR Industrial Accessories supplies this brand and can help you confirm the right seal for the job.

Dimensions for the DBH 6921 are shaft 108.05 mm, housing 142.88 mm and height 13.00 mm. The Kz design uses a sealing lip with metal reinforcement, which suits oil or grease retention on a rotating shaft. Within the DBH line, 6921 is the code that pins down this exact size. Measure the housing bore and shaft before installation; a small mismatch is enough to cause leaks or early wear.

Seals of this size commonly appear in gearboxes, speed reducers, centrifugal pumps, mixers and power transmission equipment. There they hold lubricant in place and keep dust, water and particles away from the bearings. Agricultural and industrial machinery with moderate shaft speeds and oil present is another typical setting. For high temperatures or high peripheral speeds, ask us about the lip material before you order.

Selection and installation come down to rotation speed, service temperature and the lubricant in use. In the Kz design, the lip normally faces the fluid being retained. Coat the lip with lubricant before pressing the seal in, and use a proper mounting tool so the lip is not damaged. The housing should be free of burrs and the shaft free of wear. When a seal has already failed, check shaft alignment and bearing clearance as well. These steps help the replacement last.

For an equivalent, send the 6921 code or the measurements of your sample. We can search other brands or series with matching dimensions, and we can also identify the seal from the equipment or a drawing. The more detail you provide — shaft and housing diameter in particular — the faster we can quote. Message us on WhatsApp and we will come back with the options.
