This item is a radial shaft seal from the DBH line, identified by the designation 1256Pol. Its standard dimensions are 21 mm shaft diameter (d), 35 mm housing bore (D) and 10.00 mm height (h), with an A 079 design. The sealing lip runs on the rotating shaft and the outer case fits into the housing to maintain sealing. It is a standard replacement part for equipment that needs to retain oil or grease and exclude dust and water.

Typical applications include gearboxes, centrifugal pumps, electric motors, compressors and belt or chain drive systems. In all cases, the seal protects bearings and gears from premature wear. It is also used in equipment in the food, chemical and process industries, where cleanliness and lubricant retention are critical to operation.

To select correctly, check that the shaft and housing dimensions match those of the seal. The shaft surface must be ground and free of splines; the housing must be clean and free of burrs. During installation, lubricate the lip and use a suitable installation tool so as not to damage it. If the equipment runs at high speed or temperature, ask us about material and design variants.
