The DBH 1114Pol is a radial shaft seal with a lip-type design that keeps lubricant in and contaminants out of equipment with a rotating shaft. Its A 103-R H configuration features a stepped mounting height of 12.0/19.5 mm, allowing it to seat in chambers with a shoulder. It is commonly found in pumps, motors, gearboxes and reducers where the shaft passes through a fixed housing and a dependable barrier is required.

This seal is identified as DBH 1114Pol and its mounting dimensions are: shaft 45 mm, housing 72 mm, height 12.0/19.5 mm. The A 103-R H design indicates a sealing lip with a stepped body: the 12.0 mm section fits into the housing, while the 19.5 mm section covers the shoulder or step on the shaft. Verify these dimensions before ordering, as they determine whether the seal seats correctly in the chamber.

Seals of this type are used in rotating equipment to separate two environments: the lubricated side and the exposed side. They are found in centrifugal pumps, electric motors, gearboxes, reducers, rollers and transmission shafts. In each case, the seal works against the rotating shaft and the fixed housing, retaining oil or grease and blocking dust, wash water or particles around the machine.

When selecting a seal, also inspect the shaft condition. The track where the lip runs must be smooth and free of deep marks; a groove or scratch will cause leakage at that point. Check that the housing has no burrs and that the shoulder where the 19.5 mm height rests is clean and square. During installation, lubricate the lip with the same grease or oil used in the equipment and avoid hitting or deforming it, since the lip performs the sealing function.

To request a quote for part number 1114Pol, send the dimensions of the old seal—shaft diameter, housing diameter and height—along with a photo of the part and the housing. With this information we can find the equivalent in the DBH line or in another brand we supply. If the seal has a special design such as A 103-R H, specify it so you do not receive a single-height seal that does not cover the shoulder.
