The DBH 1229 radial shaft seal is a rotary shaft seal that prevents lubricant leakage and the ingress of contaminants in gearboxes, pumps and electric motors. Its Lz design combines a sealing lip with a secondary exclusion lip, which improves performance in dusty or dirty environments. With dimensions of 38 mm shaft, 52.25 mm housing and 7.00 mm height, it is press-fitted into the housing and runs on the shaft with a lubricant film that ensures sealing and low friction.

This item is a radial shaft seal from the DBH brand, identified by part number 1229. Its dimensions are 38 mm shaft diameter (d), 52.25 mm housing diameter (D) and 7.00 mm height (h). The Lz design indicates that it has a main sealing lip and a secondary exclusion lip, generally facing outward to retain grease and repel particles. It is made with an elastomer resistant to oils and greases, and a metal spring that ensures constant lip pressure on the shaft.

It is used in equipment where there is rotation and a need to retain lubricant: gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain drives. It is also common in agricultural and industrial applications operating in dusty environments, where the exclusion lip of the Lz design provides an additional barrier against contamination. It is a wear part that should be replaced when leaks or abnormal bearing noise appear.

To install it, check that the shaft measures 38 mm and has suitable roughness, with no burrs or marks that could damage the lip. The 52.25 mm housing must be clean and free of deformation; applying a thin layer of lubricant compatible with the elastomer before pressing the seal in is recommended. The 7.00 mm height defines the required axial space. When selecting a replacement, consider the rotation speed, working temperature and the type of fluid to be retained; the Lz design is appropriate when there is exposure to dust or dirt.
