The DBH 1232 radial shaft seal is a lip seal designed for 100 mm rotating shafts, with a 135 mm housing bore and a 12 mm height. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that accelerate wear on bearings and bushings. It is press-fitted into the housing and runs on the shaft surface, so correct selection and installation are key to avoiding premature leaks.

This item is a seal from the DBH line, identified by the designation 1232. Its dimensions are shaft (d) 100 mm, housing (D) 135 mm and height (h) 12.00 mm. The Lx design indicates a configuration with a sealing lip and spring, suitable for applications requiring sealing against oils and greases. DBH is an official brand that MR Accesorios Industriales carries, so you can ask for a quote and compatible alternatives.

Radial shaft seals like this one are used in gearboxes, pumps, electric motors, conveyor rollers and power transmission equipment. They also appear in agricultural machinery, linear guideways and hydraulic systems where a rotating shaft must be isolated from the environment. In all these cases, the seal protects the bearings and extends the service life of the assembly, provided the correct size is chosen and it is installed without damaging the lip.

To select this seal correctly, check that the shaft diameter, housing bore and height match the values on the product page. The shaft surface must be ground and free of burrs; the housing must be clean and free of deformation. During installation, lubricate the lip and use an insertion tool that presses on the outer ring, never on the lip. If the shaft shows wear, consider a seal with an auxiliary lip or a wear sleeve.
