This item is a radial shaft seal from the DBH brand, identified with the designation 1143Tef. According to the product page data, it is intended for an 85 mm diameter shaft. The A 376-R AH design defines a sealing lip with a spring that ensures constant contact on the shaft. To confirm the housing and height, it is essential to verify the manufacturer's technical data sheet.

Radial shaft seals such as the DBH 1143Tef are used in gearboxes, pumps, electric motors, rollers and transmission equipment. Their main function is to prevent oil or grease leaks and to protect the bearings from the ingress of dust, water or particles. In environments with vibration or moderate speeds, a seal with a spring-loaded lip offers durable, low-maintenance sealing.

To correctly select this seal, take into account the shaft diameter, the type of lubricant, the operating temperature and the peripheral speed. Mounting must be done with a clean, burr-free shaft, using a suitable tool so as not to damage the lip. If the housing shows wear, consider a seal with a greater height or a wear sleeve. Always verify that the A 376-R AH design is compatible with the conditions of your equipment.
