Its height of 7.00/14.00 mm corresponds to an A 361 design, with an asymmetrical section lip that improves contact and lubricant retention. It is used to contain oil or grease and exclude dust and water in gearboxes, pumps and power transmission equipment.

This item is a radial shaft seal from the DBH line, identified with the code 9976. Its dimensions are shaft (d) 21 mm, housing (D) 61 mm and height (h) 7.00/14.00 mm. The A 361 design defines a profile with a sealing lip and a body of variable height, designed for housings with a shoulder or to cover a mounting range. The lip runs on the rotating shaft and the outer face rests on the housing, creating the tight seal.

Typical applications of a seal of this size include gearboxes, electric motors, centrifugal pumps, rollers and power transmission equipment. In all cases it performs two functions: retain the lubricant inside the assembly and prevent the entry of contaminants such as dust, water or particles. It is a wear part, so it is advisable to inspect it when leaks or bearing noise appear.

To select correctly, verify that the shaft and housing diameters match the indicated values. The lip should have a slight interference on the shaft, without excess that generates heat. During installation, lubricate the lip, avoid hitting it and use a tube or press that rests on the outer face. If the shaft shows wear or grooves, evaluate a repair sleeve or an alternative size.
