A radial shaft seal from the DBH line, the 9535Pol closes the gap between a rotating 127 mm shaft and a fixed housing bore of 152.43 mm, with a section height of 12.70 mm. Its job on the equipment is twofold: hold the oil or grease where it belongs and keep dust, water and other particles out of the bearing cavity. Whenever a shaft spins inside a stationary housing, this kind of barrier is what protects the bearings and bushings from premature wear.

The designation 9535Pol belongs to the DBH seal range. Reading the size is straightforward: 127 mm is the shaft it runs on, 152.43 mm is the bore it presses into, and 12.70 mm is the overall height. The Kz execution is a single lip with a spring, intended for rotating shafts lubricated with oil or grease. The elastomeric lip contacts the shaft while the metal outer case holds the seal firmly in the housing. Because the sealing edge is precision-made, it needs careful handling at every step.

Seals in this size range show up in gearboxes, centrifugal pumps, electric motors, mixers and power transmission equipment. In each case the task is the same: retain lubricant and block contaminants. Plants running continuous processes often rely on them, since a leaking seal can disrupt production or create an environmental issue. Treating the seal as a critical part of the rotating assembly is the right approach.

Selecting a replacement means confirming three values: shaft diameter, housing bore and available height. The shaft surface should be free of burrs and have the hardness and roughness the lip needs, otherwise the edge will be cut. During installation, coat the lip with the same oil or grease used in the equipment and press on the metal case with a proper tool, never on the elastomer. A seal driven in crooked or hit with a hammer is the most frequent cause of early leakage.

For an equivalent, the fastest route is to send the code 9535Pol or the current shaft, bore and height measurements. With that information the team can search other brands or lines carried by MR. They can also help when mounting space is tight or the original seal is no longer produced, so a sealing part does not leave the equipment down.

DBH is one of the brands MR supplies, and this seal sits alongside the rest of the seals and oil seals in the catalog. To request a quote for the 9535Pol, send the code on WhatsApp or by email and the team will come back with the technical and commercial details.
