This item is a DBH radial shaft seal, identified by the designation 1147. Its dimensions are 122.20 mm shaft diameter (d), 152.40 mm housing diameter (D) and 27.00 mm height (h). Design A 088 corresponds to a specific lip and case configuration that defines its behavior in service. It is a precision component that is press-fitted into the housing and seals against the moving shaft, preventing oil or grease leaks and the entry of external particles.

Radial seals such as the DBH 1147 are used in gearboxes, pumps, electric motors, rollers and power transmission equipment. They are common in the food, cement, mining and process industries, where shafts rotate in environments with dust, moisture or frequent washdowns. Their selection depends on rotation speed, operating temperature and the type of lubricant. In all cases, the seal must maintain uniform contact with the shaft to guarantee long-lasting sealing.

To fit this seal correctly, check that the shaft has no burrs or wear and that the housing is clean and undamaged. Lubricate the lip with the same oil or grease used in the equipment before inserting it. The 27.00 mm height must match the housing depth to avoid deformation. If the shaft has splines or grooves, consider using a wear sleeve. Fitting pressure must be axial and uniform, never striking directly on the lip.
