The DBH 9142 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or particles. With dimensions of 28 mm shaft diameter, 56 mm housing and 7 mm height, it press-fits into covers, gearboxes, pumps and motors. It is a wear part that should be replaced at the first sign of leakage. MR Accesorios Industriales carries it as an official brand.

This item is a radial shaft seal from the DBH brand, identified by code 9142. Its nominal dimensions are 28.00 mm shaft diameter (d), 56.00 mm housing diameter (D) and 7.00 mm height (h). The Lx design corresponds to a single-lip seal with spring, without an external dust lip, suitable for rotating shafts with internal lubrication. The sealing lip works on the shaft and the outer casing fits into the housing. These dimensions are those listed in the manufacturer's data sheet and must match the seat before mounting.

Typical applications for a 28x56x7 mm seal include gearboxes, reducers, centrifugal pumps, electric motors, compressors and transmission equipment. It is generally found on input or output shafts where there is contact with oil or grease and the lubricant needs to be contained. It is also used to protect bearings and bushings from environmental dust. If the equipment operates with high vibration or misalignment, it is advisable to check the condition of the shaft and housing before replacing the seal.

To correctly select a seal, three dimensions must be checked: shaft diameter, housing diameter and height. Additionally, rotation speed, operating temperature and the type of fluid to be retained must be considered. The Lx design is suitable for shafts with moderate speed and oil lubrication. During installation, lubricate the lip with the same oil used in the equipment, insert the seal perpendicularly and strike only on the outer circumference. Avoid damaging the lip with shaft burrs or sharp tools.
