The DBH 9639 radial shaft seal is a lip seal that keeps lubricant in and contaminants out of rotating equipment. It fits a 30 mm shaft, a 58.10 mm housing bore and an 11.00 mm width, and uses the Mz-R design with a spring-loaded lip. This seal is a common choice for gearboxes, pumps, motors and other industrial machinery where reliable sealing matters.
The part number DBH 9639 identifies a radial shaft seal with these dimensions: shaft diameter (d) 30 mm, housing diameter (D) 58.10 mm, and height (h) 11.00 mm. The Mz-R designation refers to a seal that has a sealing lip and a spring, which maintains steady contact against the shaft. These dimensions and features allow it to fit standard housings and shafts with the appropriate tolerances.
You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In each case, it stops oil or grease from escaping and blocks dust, water and other particles from entering. Because a failed seal can lead to unplanned downtime and damage to bearings and gears, it is a critical item in any maintenance program.
Before installation, confirm that the shaft and housing dimensions match the values above. The shaft surface should be free of burrs, scratches and heavy wear, and a suitable finish helps extend lip life. Lubricate the lip with the same oil or grease used in the equipment, then press the seal in with a tool that applies even force on the outer ring. Avoid hitting the sealing lip directly.
If you need a seal with equivalent dimensions or a close variant, we can help. We supply the DBH line and other sealing options. To speed up the search, have the code 9639, the shaft, housing and height dimensions, and the application details ready. Our team can recommend the most suitable option based on your working conditions.
