Description

DBH 9730Pol is a radial shaft seal reference, within Seals. Request a quote for 9730Pol via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.

The DBH 9730Pol radial shaft seal is a lip seal designed to stop oil or grease from escaping on rotating shafts and to keep out dust, water or particles. It is press-fitted into the housing and runs on the shaft with a flexible lip that maintains sealing during rotation. It is a common wear part in gearboxes, pumps, electric motors and power transmission equipment, where a small leak ends up affecting bearings and gears. MR Accesorios Industriales supplies this official brand and advises you on choosing the right size.

This DBH 9730Pol oil seal has a shaft diameter of 25 mm, a housing diameter of 37 mm and a height of 8.00 mm. Design A 156-R-H corresponds to a radial lip configuration with an outer metal case, intended for rigid housings and shafts with a good surface finish. The 9730Pol designation identifies the size within the DBH line, and it is advisable to verify that it matches the seal you are replacing before ordering it.

It is used in equipment with continuous rotation and contact with lubricant: gearboxes, centrifugal pumps, motors, compressors, mixers and conveyors. It also appears in machine tools and process equipment where external contamination shortens bearing life. If the original seal has lost its elasticity, hardened or shows cuts on the lip, replacing it with the same size is the most direct way to restore sealing.

To install it, clean the housing and the shaft, check that there are no burrs or wear marks and lubricate the lip with the same grease or oil used in the equipment. The seal must go in perpendicular, without blows that deform the case. Also check the condition of the shaft: a scored raceway or excessive play makes any new seal fail in a short time. In those cases it is advisable to consider a wear sleeve or to correct the surface.

If you cannot find part number 9730Pol or you need a nearby size, send us the shaft, housing and height dimensions along with a photo of the old seal. With that data we look for the equivalent within the DBH line or other brands we supply. We can also advise you if design A 156-R-H is not suitable for your application and a different lip or material configuration is needed.

MR Accesorios Industriales works with seals and oil seals for maintenance and replacement. Send part number 9730Pol or the dimensions by WhatsApp and we will quote it. If you have doubts about installation or about compatibility with the equipment lubricant, ask us before installing: a poorly selected seal degrades quickly and creates the leak you wanted to solve again.

Frequently Asked Questions

What dimensions does the DBH 9730Pol oil seal have?
It corresponds to a 25 mm shaft, 37 mm housing and 8.00 mm height, with design A 156-R-H. These are the dimensions shown in the designation, and it is advisable to compare them with the seal you are going to replace before ordering it.
How do I request the equivalent if I do not have the part number?
Send the shaft, housing and height dimensions by WhatsApp, plus a photo of the old seal. With that we look for the equivalent in the DBH line or in other brands we supply and confirm the option for you.
What should I check before installing it?
The housing and the shaft must be clean, without burrs or scratches. Lubricate the lip with the same oil or grease used in the equipment, insert it perpendicular and avoid blows. If the shaft has play or wear, the new seal will not seal properly.
