When a rotating shaft needs its lubricant kept in and outside contamination kept out, a radial shaft seal such as the DBH 6694Pol does the job. Its designation spells out the fit: a 52.40 mm shaft, an 81.00 mm housing bore and an 11.00 mm height, with an Lz-R lip configuration. MR Industrial Accessories carries this seal within its seals and oil seals range for maintenance and replacement work.

Reading the code is the quickest way to confirm a match. The 6694Pol reference comes from DBH, and the lip geometry is the Lz-R type: a sealing lip backed by a spring that keeps steady pressure against the shaft. Elastomer and spring together hold the sealing action through continuous running, which is what makes this style a common choice on shafts turning at moderate speeds.

You will run into seals like this on gearboxes, pumps, electric motors, mixers and power transmission assemblies. Their role is twofold: hold oil or grease inside the housing and keep bearings and gears clear of dust, water and particles. In plant settings they show up on process lines, conveyors and farm machinery, where planned maintenance means replacing them on a schedule rather than waiting for a leak.

Before ordering, check three things against the equipment: shaft diameter, housing bore and housing depth. The first two must match the seal exactly, and the height has to sit correctly in the bore. The Lz-R design suits single-direction rotation at moderate peripheral speeds. Fit the seal with the lip lubricated and a proper installation tool so the lip is not nicked, and if the shaft surface is worn, a repair sleeve is worth considering.

Need a cross-reference? Send the 6694Pol code or the dimensions of the seal you are replacing through WhatsApp, and we will search our seals and oil seals line for an alternative that keeps the same shaft, housing and height. We can also talk through material choice based on the fluid in contact and the working temperature.
