The DBH 1114Pol oil seal is a lip-type radial shaft seal designed to stop lubricant from escaping and to block dust, water or particles from entering rotating shaft equipment. Its A 103-R H design combines a sealing lip with a stepped mounting height of 12.0/19.5 mm, which allows it to be seated in chambers with a shoulder. It is used in pumps, motors, gearboxes and reducers where the shaft passes through a fixed housing and a reliable barrier is required.

This item is a DBH radial shaft seal identified as 1114Pol, with the following mounting dimensions: shaft diameter 45 mm, housing diameter 72 mm and height 12.0/19.5 mm. The A 103-R H design corresponds to a seal with a sealing lip and a stepped-height body: the 12.0 mm section fits into the housing and the 19.5 mm section covers the shoulder or step on the shaft. These dimensions are the ones you need to verify before ordering, because they determine whether the seal seats correctly in the chamber.

Radial shaft seals of this type are mounted on rotating equipment where two environments must be separated: the lubricated side and the exposed side. They appear in centrifugal pumps, electric motors, gearboxes, reducers, rollers and transmission shafts. In all these cases the seal works against the rotating shaft and the fixed housing, and its function is to retain the oil or grease and block dust, wash water or particles circulating around the machine.

To choose the right seal, in addition to the dimensions, check the condition of the shaft: the track where the lip rests must be smooth and free of deep marks, because a groove or a scratch will cause the seal to leak there. Also check that the housing has no burrs and that the shoulder where the 19.5 mm height rests is clean and square. When mounting it, lubricate the lip with the same grease or oil used in the equipment and avoid hitting or deforming it, because the lip is the part that does the sealing work.

If you cannot find the 1114Pol part number or you need a nearby size, the most practical thing is to send us the dimensions of the old seal: shaft diameter, housing diameter and height, plus a photo of the part and the housing. With that data we look for the equivalent in the DBH line or in another brand we carry. If the seal has a special design, such as A 103-R H, it is best to point that out so you don't receive a single-height one that does not cover the shoulder.
