When you need to keep lubricant in and contaminants out of a rotating assembly, the DBH 5159 radial shaft seal is a direct-fit option. It suits a 25.40 mm shaft, a 37 mm housing bore, and a 7.50 mm height, and it uses the Lz lip configuration. MR Industrial Accessories supplies this seal and can help you confirm the dimensions before you order.
The 5159 code identifies a lip seal from the DBH line. Its key measurements are shaft diameter (d) 25.40 mm, housing diameter (D) 37 mm, and height (h) 7.50 mm. The Lz design refers to a standard sealing lip for general-duty service. Always compare these three figures against your shaft and housing before installation; they decide whether the seal seats and seals correctly.
You will find seals of this size in gearboxes, centrifugal pumps, electric motors, compressors, and belt or chain drives. The job is always the same: hold oil or grease inside the assembly and block dust, water, or particles that would otherwise shorten bearing and gear life. Fan, mixer, and conveyor shafts also use this type of closure, especially where moisture or airborne debris is present.
Proper installation matters as much as correct sizing. Lubricate the lip before you press it in, and use a mounting sleeve or tool so the lip does not roll or tear. Inspect the shaft for burrs, scratches, or wear; a damaged surface will not let the lip seal properly. The housing should be clean and free of dents or distortion. If the shaft is worn, a seal with an auxiliary lip may be a better choice.
