The DBH 1126 is a radial shaft seal designed to keep lubricant in and contaminants out of rotating shaft equipment. Its A 109 configuration and compact footprint make it suitable for pumps, motors, gearboxes, and conveyor rollers. MR supplies this seal and can help you confirm the right fit for your application.

This seal has a shaft diameter of 48.90 mm, a housing bore of 63.00 mm, and a height of 10.80 mm. The lip rides on the shaft while the outer diameter seats into the housing with an interference fit, providing sealing in both directions. The A 109 designation refers to the lip and case geometry—worth checking against the manufacturer's data sheet before swapping out an existing part.

Typical uses include centrifugal pumps, electric motors, reducers, gearboxes, belt conveyor rollers, and machine tools. In dusty or wet environments, this seal helps prevent lubricant contamination and oil loss. If the equipment runs with vibration or misalignment, inspect the shaft and housing condition before installing a new seal.

When selecting a radial shaft seal, consider shaft diameter, housing diameter, height, lubricant type, temperature range, and shaft speed. The DBH 1126 uses a standard single-lip design with a spring. During installation, lubricate the lip with the same oil or grease used in the equipment, ensure the shaft is free of burrs, and press the seal in square without hitting the lip. A damaged housing may require a repair sleeve or alternate size.
