The DBH 9641 is a radial shaft seal built to hold lubricant in and keep dust, water and other particles out where a shaft passes through a housing. It measures 18.00 mm at the shaft, 32.00 mm at the housing and 7.00 mm in height, and it uses the Lx design. MR Industrial Accessories supplies this seal within its seals and oil seals range for customers in the United States and Latin America.

Reading the number is straightforward: 9641 is the designation you quote, and the three figures that follow describe the fit. Shaft 18.00 mm, housing 32.00 mm, height 7.00 mm. The Lx design refers to a single lip with a metal case, a configuration intended for rotating shafts that run with lubrication. Knowing this helps a maintenance tech confirm a replacement against the old part before pulling anything apart.

Seals in this size range turn up in small centrifugal pumps, low power electric motors, gearboxes, compressors, machine tools and power transmission equipment. The job is always the same: keep oil or grease where it belongs and block contamination from reaching bearings, bushings and gears. Because the lip wears against the shaft, the seal is a consumable item and should be changed once lubricant starts escaping or the area gets noisy.

Installation calls for a clean shaft, free of burrs and scratches, and a housing bore that matches the 32 mm figure with the 7 mm height available. Lubricate the lip before pressing the seal in, keep it square to the shaft, and apply force evenly on the metal case rather than on the lip. A repair sleeve is worth considering when the shaft surface is worn. Final selection still depends on shaft speed, operating temperature and the lubricant in use.

To get a quote, send the 9641 code or the 18 x 32 x 7 mm dimensions by WhatsApp or email. We can confirm the seal, check other options in the same category and advise on the lip design that fits your shaft and working conditions. If you only have a sample, or you can measure the housing and shaft, we can help identify the correct seal.
