The DBH 6112Pol radial shaft seal is a lip seal designed to keep lubricant in and prevent contaminants from entering rotating equipment. Its dimensions of 31.70 mm shaft, 44.60 mm housing and 6.70 mm height, together with the Mx-R H design, make it suitable for shafts rotating at moderate speeds that require a reliable barrier against dust, water and particles. It is press-fitted into the housing bore and runs on the shaft surface, where the lip maintains dynamic contact.

This item is a seal from the DBH line, identified by the code 6112Pol. Its standard dimensions are 31.70 mm shaft diameter (d), 44.60 mm housing diameter (D) and 6.70 mm height (h). The Mx-R H design corresponds to a configuration with a sealing lip and a specific geometry for retaining oil or grease in rotating applications. The lip elastomer and the outer metal reinforcement are integrated to withstand mounting pressure and maintain sealing during rotation.

Radial shaft seals such as the 6112Pol are used in gearboxes, pumps, electric motors, transmission shafts and process equipment where lubricant must be contained and dirt excluded. They are common in the food, chemical and materials handling industries, provided the lip material is compatible with the fluid and the operating temperature. They also appear in machine tools and linear motion equipment that require a compact, low-friction seal.

To install this seal, verify that the shaft diameter is within the recommended tolerance and that the contact surface is polished and free of grooves. The housing bore must have the correct diameter and depth to accommodate the 6.70 mm height without deforming the lip. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and use an installation tube that presses on the outer ring, never on the lip. Avoid impacts and check concentricity to prevent damaging the seal.
