The DBH 1140 oil seal is a single-lip radial shaft seal designed for rotating shafts of 69 mm diameter and housings of 86 mm. Its height of 7.00/15.00 mm corresponds to a profile with dual mounting height, which allows it to adapt to different housing depths. It is made of elastomer resistant to oils and greases, and its A 373 design ensures effective sealing against leaks and contaminants. It is a key part for maintaining lubrication and protecting bearings in industrial equipment.

This DBH 1140 oil seal has a designation that reflects its main dimensions: 69 mm shaft diameter, 86 mm housing diameter and a height of 7.00/15.00 mm. The A 373 design indicates a single-lip configuration with spring, intended for rotating shafts. The dual height allows the seal to adapt to housings with different depths, offering versatility in mounting. It is a radial sealing component that prevents lubricant leakage and the entry of dust or water.

Oil seals such as the DBH 1140 are used in gearboxes, pumps, electric motors, conveyor rollers and power transmission equipment. Their function is to retain the oil or grease inside the assembly and exclude external particles that could damage the bearings. They are common in applications where the shaft rotates at moderate speeds and a reliable barrier is required. They are also used in agricultural machinery, process equipment and linear motion systems.

To correctly select this oil seal, verify that the shaft and housing diameters match the indicated dimensions. The shaft surface must be ground and have adequate hardness to prevent premature lip wear. It is important to lubricate the lip before mounting and to use a tool that does not damage the seal. The 7.00/15.00 mm height allows the position to be adjusted according to the available depth. If the housing has a different depth, ask about other variants.
