The DBH 8168 is a radial shaft seal designed to contain oil or grease where a rotating shaft exits a housing, while also blocking dust, water, and other contaminants. It fits gearboxes, pumps, electric motors, and similar power transmission equipment. The A 135 design pairs a sealing lip with a metal case that presses into the housing bore.

The seal carries part number 8168 and follows the A 135 design. Its dimensions are shaft 24.50 mm, housing 47.00 mm, and height 7.00/11.00 mm. The two height figures indicate a stepped profile: the shorter section seats in the housing, and the taller section carries the lip that contacts the shaft. This configuration is typical when an extra lip is included for contaminant protection.

Seals in this size range suit equipment with small-diameter shafts running at moderate speeds. Common locations include gearboxes, electric motors, centrifugal pumps, compressors, machine tools, and belt or chain drives. They also appear in agricultural implements and process machinery where lubricant retention and exclusion of washdown water or airborne dust are both required.

Selection and installation call for three checks. First, confirm the shaft diameter is within the recommended tolerance and free of nicks or burrs. Second, verify the housing bore diameter and depth. Third, lubricate the lip before assembly. Press the seal in squarely using a press or a support tube that bears on the outer edge, never by striking the lip. If the shaft is worn, a repair sleeve may be an option.

For a cross-reference or the same seal from another manufacturer, send part number 8168 together with the shaft, housing, and height dimensions. With those details we can match the designation, the A 135 design, and the dimensions to suggest a compatible alternative. We can also check whether the housing can accept a different height within the same seal category.
