This item is a DBH radial shaft seal, identified with code 8253. Its dimensions are 28.00 mm shaft diameter (d), 56.00 mm housing diameter (D) and 8.00 mm height (h). Design A 106 corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The designation 8253 is the reference you will find on the manufacturer's product page and the one you should mention when asking for an equivalent or a replacement part.

Typical applications for an oil seal of these dimensions include gearboxes, centrifugal pumps, electric motors, reducers and transmission equipment. In all cases it serves to keep oil or grease inside the assembly and prevent the entry of dust, water or particles. It is a wear part that should be replaced when leaks appear or when the lip shows hardening or visible wear.

For installation, check that the shaft and housing are clean, free of burrs and marks. Lubricate the lip with the same oil or grease used in the equipment before inserting it and avoid striking it during placement. Oil seal selection should consider shaft speed, working temperature and the type of lubricant. If the equipment operates with high vibration or pressure, a design with additional reinforcement may be advisable.
