The DBH 5144 is a radial shaft seal built to hold lubricant in place and keep contaminants out of rotating assemblies. Its dimensions are 45.00 mm at the shaft, 72.00 mm at the housing and 10.00 mm in height, and it uses the Lz configuration, a single sealing lip with a spring. You will find this size in gearboxes, pumps, motors and other transmission equipment. MR Industrial Accessories supplies the DBH line and can help you match the seal to your application.

Reading the code is the first step. The 5144 designation ties back to a standard size set: a 45.00 mm shaft, a 72.00 mm housing bore and a 10.00 mm overall height. The Lz layout means one elastomeric lip backed by a spring, which is the common choice for lubricated rotating shafts. The lip rides against the shaft while the outer diameter holds the seal in the housing. Treat it as a wear part: it is what keeps bearings, bushings and gears free of contamination and stops oil from escaping.

Seals of this size show up in gear reducers, centrifugal pumps, electric motors, compressors, and chain or belt drives. Machine tools, conveyors, and agricultural or road equipment that run shafts in dusty or wet conditions also use them. The job is always the same: keep the oil inside the assembly and keep outside elements away from the rolling and lubrication areas.

Installation matters as much as the part. Check the shaft for burrs or deep marks where the lip will run, and make sure the housing bore is clean and not distorted. Lubricate the lip before pressing the seal in, and use a driver of the right diameter so the spring and elastomer are not damaged. When you select a replacement, look at shaft speed, operating temperature and the fluid being retained. If the original seal has a different lip style or material, an equivalent can be reviewed.

If you are replacing a DBH 5144, the fastest route is to send the complete code along with the equipment brand and a photo of the old seal. That lets us compare shaft and housing diameters, height and lip type, and propose an option that does the same job. We can also check whether the Lz design fits your speed and temperature conditions.
