The DBH 9438 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. With dimensions of 44 mm shaft, 70 mm housing and 8 mm height, and Lx design, it is a common replacement part in gearboxes, pumps and power transmission equipment. MR Accesorios Industriales supplies it as part of its seals line.

This item is a radial shaft seal from the DBH brand, identified by part number 9438. Its nominal dimensions are 44 mm shaft diameter, 70 mm housing diameter and 8 mm height, with an Lx design. This set of data defines the seat: the lip runs on a 44 mm shaft and the body fits into a 70 mm bore with 8 mm usable depth. It is a compact-section seal, designed for spaces where a taller seal will not fit.

Typical applications for a seal of this size are gearboxes, electric motors, centrifugal pumps, mixers and belt- or chain-driven transmission equipment. In all these cases it performs the same function: keeping oil or grease inside the assembly and preventing the entry of contaminants that accelerate wear on bearings and gears. It is also used as a secondary closure on fan and conveyor shafts.

For correct installation, check that the 44 mm shaft has no burrs or deep marks in the lip contact area, and that the 70 mm housing is clean and free of deformation. Lubricate the lip before inserting it and apply force on the outer ring, never on the lip. If the equipment runs with high vibration or temperature, it is worth evaluating a design with a spring or an alternative material, always respecting the 44 x 70 x 8 dimensions.

If you need a seal equivalent to the 9438, the most practical approach is to send us the part number and the shaft, housing and height dimensions. With that data we can look for an alternative within the same category or confirm whether there is an Lx design variant with a different height. We can also advise you if the housing accepts a seal with an additional lip or with a dust guard, depending on the type of contamination in the equipment.
