The DBH 1207/85 radial shaft seal is a lip seal that mounts on the shaft and closes off the passage of oil or grease in crankcases, gearboxes and rotating equipment. Its A 392 design combines a sealing lip with a dust lip, which improves protection against dust and dirt in demanding environments. With dimensions of 22 mm shaft, 47 mm housing and a height of 5.50/10.00 mm, it is a common replacement part in industrial maintenance.

This item is a DBH brand oil seal, identified by the designation 1207/85 and design A 392. Its nominal dimensions are 22 mm shaft diameter, 47 mm housing diameter and a height of 5.50/10.00 mm. Design A 392 corresponds to a seal with a double lip: one main sealing lip and one dust lip, designed to retain lubricant and at the same time block the entry of contaminants. The stepped height of 5.50/10.00 mm indicates that the dust lip protrudes relative to the sealing body, a detail to keep in mind when checking the space available in the housing.

Typical applications for this oil seal include gearboxes, electric motors, pumps, mixers and transmission equipment where a rotating shaft needs to be sealed against oil or grease leaks. It is also used in environments with dust or particles, where the dust lip of design A 392 provides an additional barrier. It is a wear part that should be replaced when dripping appears, shaft play is detected or a major repair of the equipment is carried out.

To correctly select an oil seal, you must verify the shaft diameter, the housing diameter and the available height. In this case, the values are 22 mm, 47 mm and 5.50/10.00 mm respectively. In addition, it is important to check the condition of the shaft surface: it must be ground, free of grooves or wear, and with adequate hardness so as not to damage the lip. During installation, lubricate the lip with the same oil or grease used in the equipment, insert the seal perpendicularly and avoid striking it directly. If the housing has burrs, correct them before fitting the part.
