The DBH 1148 oil seal is a labyrinth-type radial shaft seal used to prevent lubricant leaks and the ingress of contaminants in rotating equipment. Its standardized dimensions make it suitable for 120.60 mm shafts and 152.40 mm housings, with a height of 27.00 mm. It is a key component in the reliability of gearboxes, pumps and other mechanisms where efficient sealing extends bearing service life and reduces maintenance.

This DBH 1148 oil seal has a shaft diameter of 120.60 mm, a housing diameter of 152.40 mm and a height of 27.00 mm. Its A 108 design corresponds to a configuration with a sealing lip and spring, which ensures uniform contact on the shaft. It is manufactured with high-resistance elastomers and a metal case that facilitates press fitting into the housing. It is a reliable solution for applications requiring durable, abrasion-resistant sealing.

Typical applications for this oil seal include speed reducers, gearboxes, centrifugal pumps, mixers and power transmission equipment. In all these cases, the oil seal prevents the loss of oil or grease and protects the bearings against dust, water and foreign particles. Its size and design make it suitable for industrial machinery operating under severe conditions, where tight sealing is critical to avoid unscheduled downtime and repair costs.

For correct installation, verify that the shaft and housing are clean, free of burrs and scratches. Lubricate the seal lip with the same oil or grease used in the equipment before inserting it. Insert the seal perpendicular to the shaft, using an installation tube that presses on the metal case, never on the lip. Make sure the spring is correctly positioned. If the shaft shows wear, consider using a repair sleeve or an alternative size.
