The DBH 6858Pol oil seal is a single-lip radial seal that mounts on rotating shafts to retain lubricant and block the entry of dust, water or particles. Its A 156-R H design and its dimensions of 30 mm shaft, 42 mm housing and 7 mm height make it suitable for gearboxes, pumps, electric motors and power transmission equipment. At MR Accesorios Industriales we carry it as part of our seals and oil seals line for industrial maintenance.

This item is a DBH radial shaft seal with the designation 6858Pol. Its attributes indicate a 30 mm shaft diameter, a 42 mm housing diameter and a 7.00 mm height. The A 156-R H design corresponds to a lip configuration with spring that ensures constant contact on the shaft. The DBH brand is an official brand that MR carries, so the product arrives with its factory identification and traceability.

Seals of this size are used in equipment where a shaft rotates inside a housing and the oil or grease needs to be separated from the environment. They appear in gearboxes, centrifugal pumps, electric motors, compressors, mixers and machine tools. They are also found in agricultural implements and in chain or belt drive equipment, where dust and moisture shorten bearing life if there is no adequate sealing.

To install a seal, verify that the shaft has no burrs or marks and that the contact surface is polished. The housing must be clean and free of deformation. It is recommended to lubricate the lip before inserting it and to use an installation tube that presses on the outer edge, never on the lip. If the shaft shows wear, it is advisable to consider a repair sleeve or an alternative size so as not to damage the new seal.

If you need an equivalent seal or a nearby size, send us the code 6858Pol or the shaft, housing and height dimensions. With that data we search our DBH seals line and compatible alternatives. We can also advise you if the A 156-R H design is not suitable for your application and a different lip profile or material is needed.
