The DBH 9133 oil seal is a single-lip radial seal that mounts on the shaft and closes off the passage of oil or grease in crankcases, gearboxes and pumps. Its Lx design works with the lip bearing on the rotating shaft, while the 52 mm outer diameter is press-fitted into the housing. With 34 mm shaft and 7 mm height, it is a common size in power transmission equipment and industrial machinery that needs to contain lubricant and stop dust from entering.

This item is a radial shaft seal from the DBH line, identified with part number 9133. Its dimensions are 34.00 mm shaft diameter, 52.00 mm housing diameter and 7.00 mm height, with an Lx design. The Lx design corresponds to a single sealing lip with an outer metal case, intended for rotating shafts with internal lubrication. The elastomeric lip bears on the shaft race and creates the dynamic seal, while the outer diameter keeps the seal fixed inside the housing.

Seals of this size are used in gearboxes, electric motors, centrifugal pumps, compressors and power transmission equipment. They also appear in spindles and rollers of machine tools, where they contain the lubricating oil and prevent coolant or dust from entering the bearing. In all those cases, the seal protects the lubricant and extends the service life of the bearings and gears behind the seal.

To install a seal, check the condition of the shaft: no burrs, no deep wear marks and with the roughness suitable for the lip. The housing must be clean and free of deformation. It is recommended to lubricate the lip with the same grease or oil used in the equipment before inserting it, and to use an installation tube or bushing that bears on the outer diameter, never on the lip. If the shaft shows a marked groove, it is worth considering a seal with an offset lip position or a repair sleeve.

If you need a neighbouring size or an equivalent from another brand, send us the part number engraved on the old seal, the shaft, housing and height dimensions, and a photo of the part. With that data we search the DBH line or the alternatives we supply. We can also advise you if the Lx design is not the one that corresponds to your equipment and a different type of lip or outer case is needed.
