The DBH 9203Pol radial shaft seal is a lip seal that closes off the passage of oil, grease or water between a rotating shaft and its housing. With a 57 mm shaft diameter, 71 mm housing diameter and 9.50 mm height, it is press-fitted into the housing and runs on the shaft with the lip in contact. It is a wear part: when lubricant leakage appears or dirt gets in, it is replaced.

The DBH 9203Pol is a seal of Lx-R-H design: sealing lip with spring, metal case and 9.50 mm height. The dimensions are 57 mm shaft diameter (d), 71 mm housing diameter (D) and 9.50 mm height (h). This combination defines the mounting interference in the housing and the clearance on the shaft, so it is advisable to verify all three before ordering the replacement.

It is used in gearboxes, pumps, electric motors, drive shafts and process equipment where a shaft rotates inside a housing with lubricant. It also appears in applications with dust or water, where the lip prevents contaminant ingress. In all these cases the seal is the sealing point between two zones: one with lubricant and one dry.

To select the seal, first look at the shaft diameter and the housing diameter, then the available height. The condition of the shaft matters: a scored or worn track means the lip does not seat properly, and there it is advisable to evaluate a new shaft or a seal with the lip in a different position. During installation, lubricate the lip and use a sleeve or cone that does not damage it as it passes over keyways or shoulders.

If the 9203Pol is not the size you need, send us the shaft, housing and height dimensions, plus a photo of the old seal or the part number marked on the part. With that we look for an equivalent within the DBH line and the other brands MR carries. We can also look at lip material alternatives depending on the fluid and working temperature.

DBH is a brand that MR carries, so the seal arrives with its original designation. Send the part number 9203Pol by WhatsApp to MR Accesorios Industriales and we'll quote. If you have doubts about the size or installation, write to us with the equipment data and we'll review it together.
