When a shaft needs to hold its lubricant in and keep dust and water out, a radial lip seal like the DBH 1256Pol does the job. It measures 21 mm at the shaft, 35 mm at the housing bore and 10.00 mm in height, and it carries the A 079 design. MR Industrial Accessories LLC supplies this line and works with you to confirm the seal your equipment actually takes.

Reading the code helps you order with confidence. The 1256Pol designation belongs to the DBH line of radial shaft seals, and the three figures that matter at the counter are d, D and h: 21 mm for the rotating shaft, 35 mm for the bore it presses into, and 10.00 mm of height. The A 079 design tells you how the lip and the outer case are built. The lip rides against the shaft while the case stays fixed in the housing, so oil or grease stays inside the machine and outside contamination stays out.

You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors, and belt or chain drives. In each of those spots it shields bearings and gears from the grit and moisture that shorten their working life. Plants in the food, chemical and process sectors also use it, since keeping lubricant where it belongs matters when cleanliness is part of the routine.

Selection comes down to matching the seal to the hardware. Measure the shaft and the housing bore and compare them with the 21 mm and 35 mm figures, and confirm that the A 079 design corresponds to the part you are replacing. The shaft should be ground and free of splines, and the housing clean and free of burrs. Lubricate the lip before you press the seal in, and use a proper installation tool so the lip is not nicked on the way. If the equipment runs hot or fast, ask about the material and design options available.

If you are cross-referencing, send the complete part number, the shaft and housing dimensions, and a photo of the original seal. With that, our team can look for a suitable equivalent and talk you through compatibility with other seal lines.
