The DBH 9731/85 is a radial shaft seal, also known as an oil seal or lip seal, used to keep lubricant in and contaminants out of rotating equipment. It is identified by the part number 9731/85 and has an A 016 design. With a shaft diameter of 24 mm, a housing diameter of 42 mm, and a height of 8.50 mm, it is a common size for many industrial machines. This seal helps maintain bearing life and equipment reliability by providing effective dynamic sealing.
This oil seal is built with a high-resistance elastomer lip and a metal spring that maintains consistent pressure against the shaft. The A 016 design is a standard configuration for moderate peripheral speeds and typical industrial temperatures. It is suitable for gearboxes, centrifugal pumps, electric motors, conveyor rollers, mixers, and power transmission equipment. You will also find it in agricultural machinery, mining equipment, and hydraulic systems where oil or grease must be contained and bearings protected.
When selecting a replacement, confirm that the shaft, housing, and height dimensions match your equipment. The shaft surface should be ground, free of burrs, and have adequate hardness to avoid premature lip wear. During installation, lubricate the lip with the same oil or grease used in service and use a proper installation tool to apply uniform force. Avoid striking the lip directly, as this can damage the sealing edge.
If you need an equivalent or a close variant, we can help you find alternatives in other brands or special configurations. Send us the part number 9731/85 or the exact dimensions of your shaft and housing. Our team can also advise on the lip material and spring type based on your working conditions: temperature, speed, and the fluid to be retained.
As part of our seals and oil seals line, we supply the DBH brand. If this seal is not exactly what you need, contact us via WhatsApp or email with the part number or a photo. We will assist you in finding the correct part and can suggest equivalents to keep your equipment running.
