A radial lip seal that sits between a turning shaft and a stationary housing, the DBH 9212Pol keeps lubricant where it belongs and keeps dust, water and particles out. With a 68 mm shaft, an 85 mm bore and a 9.50 mm height, it fits mid-size pumps and power transmission units. Treat it as a wear item: once the lip stiffens or shows marks, oil starts escaping and the seal is due for replacement.

The reference breaks down as follows: DBH is the line, 9212Pol is the item number, and the three figures that matter for a match are shaft diameter (d) 68 mm, housing diameter (D) 85 mm and height (h) 9.50 mm. The design called out is Mx-R H, a radial lip with a spring that keeps steady pressure against the shaft. MR supplies this DBH part under its factory designation, so the number on the box traces back to the original.

Typical homes for this size are gearboxes, centrifugal pumps, electric motors, rollers and similar transmission equipment. Anywhere a shaft spins inside a housing that holds oil, the seal does two jobs at once: it holds the lubricant in and it blocks contaminants from reaching the bearing. In food, chemical and water treatment operations that barrier is what keeps bearings running and unplanned stops away.

Installation rewards a little care. Check the shaft for tolerance and burrs first, since a scored surface will destroy the lip quickly. Coat the lip with the same oil or grease the equipment uses, then press the seal in squarely using a tube or shim that contacts only the outer ring, never a hammer directly. Where the housing has a shoulder, the seal should end up fully seated and square to the shaft.

If you need a substitute, we can search the same family for you. Just send the number 9212Pol or the three dimensions (d, D and h), a photo of the worn seal and the shaft it runs on, plus the equipment and assembly brand, and we will cross-reference the data against the options available to us.

MR Industrial Accessories LLC handles seals and oil seals regularly and can guide your choice or installation once we know how the equipment is set up. Message us on WhatsApp with 9212Pol or the dimensions and we will prepare a quote for you.
