The DBH 1237Sil radial shaft seal is a lip seal that mounts on the shaft and blocks the passage of oil, grease or contaminants in gearboxes, pumps and motors. Its A 114 design combines a sealing lip with a dust lip, making it suitable for environments with dust or dirt. With a 37 mm shaft, 72 mm housing and 12.0/14.5 mm height, it is a commonly used size in power transmission equipment.

This item is a radial shaft seal from the DBH line, identified as 1237Sil. Its dimensions are shaft (d) 37 mm, housing (D) 72 mm and height (h) 12.0/14.5 mm. The A 114 design indicates a configuration with a main sealing lip and an auxiliary exclusion lip, intended to retain lubricant and block the entry of particles. The double height (12.0/14.5 mm) corresponds to a stepped profile that improves anchoring in the housing and protection of the lip.

It is used in gearboxes, reducers, centrifugal pumps, electric motors and transmission equipment where the shaft rotates on bearings or bushings. It is commonly found in the food, chemical and process industries, where cleanliness and lubricant retention are critical. It is also used in agricultural machinery and material handling equipment operating with dust or moisture.

For installation, verify that the shaft has the proper hardness and roughness, without burrs or marks that could damage the lip. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and use an installation tube that presses on the outer diameter, never on the lip. The housing must be clean, free of dents and with the entry chamfer in good condition. If the seal operates under pressure, confirm that the design and material are compatible.
