The DBH 6697Pol is a radial shaft seal built for rotating shaft applications. It keeps lubricant where it belongs and blocks dust, particles and moisture from reaching the bearing cavity. The size reads 35 mm at the shaft, 50 mm at the housing bore and 8.00 mm in height, which makes it a common fit in gearboxes, pumps, motors and transmission assemblies. MR Industrial Accessories supplies this seal and can help you confirm the correct replacement for your equipment.

The 6697Pol designation covers the profile and lip compound of this lip seal, which uses a metal case with an elastomeric sealing element suited to oils and moderate operating temperatures. Reading the code is straightforward: 35 mm is the shaft diameter (d), 50 mm is the housing bore (D) and 8.00 mm is the overall height (h). The seal presses into the housing, and the flexible lip rides against the shaft to form a dynamic barrier.

You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors, spindles and belt or chain drives. In each case it does two jobs at once: it holds oil or grease in the sump and keeps outside contamination away from bearings and gears. Preventive maintenance programs often schedule seal replacement at set intervals precisely because a worn lip can lead to lubricant loss and premature component damage.

Installation matters as much as the part itself. Inspect the shaft for burrs, scoring or a worn contact track before fitting anything. Coat the lip with the same lubricant used in the application, then seat the seal square to the shaft, flush with the housing face or slightly recessed as the design requires. Watch for shoulders and grooves that could catch the lip on the way in, and clean both housing and shaft thoroughly beforehand.

If you are cross-referencing, send the 6697Pol number or simply your shaft and housing measurements. A photo of the old seal or the equipment nameplate also helps us identify the right option, including compatible alternatives from other brands. Quotes are handled by WhatsApp or email, and our team responds promptly with suggestions and help selecting the correct seal.
