When a gearbox, pump or motor starts weeping oil around the shaft, the usual culprit is the lip seal. The DBH 9885Pol is a single-lip radial shaft seal with a metal case, built to hold lubricant in and keep dust, water and particles out. Its size is fixed by the equipment it came from: 34.50 mm on the shaft, 59.20 mm in the housing bore and 14.00 mm wide. Design A 328 describes the lip and case geometry. Because it is a wear item, replacement follows as soon as leakage or contamination shows up.

Reading the designation helps when you reorder. The 9885Pol number identifies this seal in the DBH line, and the three figures that matter are the bore it presses into (59.20 mm), the shaft it rides on (34.50 mm) and its width (14.00 mm). Design A 328 covers the profile of the sealing lip and the metal shell. Measure your shaft and housing before sending the part number, since a seal that is off by a fraction will either leak or refuse to seat.

Seals in this size range turn up in gearboxes, centrifugal pumps, electric motors, rollers and belt or chain drives. Their job is twofold: keep oil or grease where it belongs and stop outside contamination from reaching the bearing. In washdown areas or damp rooms the lip is the first line of defense, which means the shaft surface under it needs to be smooth and free of grooves for the seal to hold.

Installation decides how long the replacement lasts. Cover threads, keyways and sharp edges with tape or a fitting sleeve so the lip is not cut on the way in, and put a light film of lubricant on the lip before pressing the seal home. Inspect the shaft for wear or scoring in the contact band. Material and lip style should match the speed, temperature and fluid involved; if the old seal failed early under harsh conditions, A 328 is the reference point for comparing alternatives.

To get a quote on the 9885Pol, send the shaft, housing and width measurements along with a photo of the removed seal. From there the team can match it within the same category or from another brand carried by MR Industrial Accessories LLC, and will tell you whether a different height or lip design suits your lubricant and operating speed better.
