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

The DBH 9203Pol is a seal with an Lx-R-H design: spring-loaded sealing lip, metal body and 9.50 mm height. The catalog 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 entry. 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, and then the available height. The condition of the shaft matters: a scratched or worn raceway prevents the lip from seating properly, and in that case it is advisable to evaluate a new shaft or a seal with the lip in another position. During mounting, lubricate the lip and use a sleeve or cone that does not damage it when passing 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 code marked on the part. With that we look for a nearby size or 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 an official brand that MR carries, so the seal arrives with its original designation. Send the code 9203Pol by WhatsApp to MR Accesorios Industriales and we will quote you. If you have doubts about the size or mounting, write to us with the equipment data and we will review it together.
