The DBH 6643Sil is a radial shaft seal sized for a 17.50 mm shaft, a 28.50 mm housing bore and a 6.00 mm height. It keeps lubricant in and contaminants out, running against a rotating shaft. You will find this type of seal in gearboxes, pumps, electric motors and power transmission equipment. MR Industrial Accessories supplies this brand and can confirm the size before you request a quote.

The code 6643Sil identifies a radial shaft seal from the DBH line. Its listed dimensions are shaft 17.50 mm, housing 28.50 mm and height 6.00 mm. The design is Lz, a single lip with spring. The seal body is elastomeric, and depending on the series it may have a metal case for rigidity during press fitting.

Seals of this size suit small-diameter shafts. Common equipment includes electric motors, centrifugal pumps, gearboxes, compressors, machine tools and transmission systems, as well as agricultural implements and materials handling equipment. Their job is always the same: separate the lubricated side from the environment, stop oil or grease from escaping and keep bearings and gears free of contaminants.

When selecting or installing a seal, check three dimensions: shaft diameter, housing size and height. The height must fit the cavity depth. Lubricate the lip before installation and make sure the shaft has no burrs or splines that could cut it. Rotation speed, working temperature and the fluid in contact determine the lip material, so confirm these details before installing.

If you need a different material or an equivalent from another brand, send us the code 6643Sil with the shaft, housing and height dimensions. A photo of the old seal or the assembly drawing also helps. With that information we verify the designation and the lip design in the DBH line that MR supplies, and we send you the quote by WhatsApp.
