The DBH 8153 seal is a radial single-lip seal with a spring, designed for rotating shafts of 55 mm diameter and housings of 85 mm. Its 12 mm height and Lx design make it suitable for retaining lubricant and excluding contaminants in gearboxes, pumps and transmission equipment. At MR Accesorios Industriales we carry it as part of our line of seals and oil seals, with more than 80 years of experience in the field.

This seal has a shaft diameter of 55 mm, a housing diameter of 85 mm and a height of 12 mm. The Lx design corresponds to a sealing lip with a spring, which maintains contact on the shaft and compensates for small misalignments. The designation 8153 identifies the exact size within the DBH line. It is a radial sealing component for rotating shafts, not for reciprocating motion or high pressures.

It is used in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In these machines, the seal prevents oil or grease leaks and blocks the entry of dust, water or particles. It is commonly found in applications where the shaft rotates continuously and the service temperature is moderate, with permanent lubrication.

To install it, check that the shaft is 55 mm and the housing 85 mm, with no burrs or marks. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and fit the seal with a press or installation tool that bears on the outer diameter, never on the lip. The 12 mm height should sit flush or as specified by the housing design. If the shaft shows wear, consider a nearby size or a seal with a wider lip coverage.

If you need an equivalent or a close size, send us the part number 8153 or the dimensions 55 x 85 x 12 mm by WhatsApp. You can also ask about other sizes in the DBH line or seals from other brands we carry. At MR Accesorios Industriales we advise you so you can choose the option that best suits your equipment, with no obligation.

Before replacing it, check the condition of the shaft and the housing: a new lip on a worn track may not seal properly. If the previous seal failed due to temperature or contamination, correct the cause before installing the new one. To confirm the application, send the part number 8153 by WhatsApp and we will reply with the available technical information.
