The DBH 9045 is a radial shaft seal that keeps oil or grease inside a housing and blocks dust and water from entering. It fits a 10 mm shaft, a 25 mm housing bore and a 7 mm height, making it a common choice for gearboxes, pumps, electric motors and power transmission equipment. Its Lx design pairs a sealing lip with a metal outer case that presses into the housing.

Key dimensions for the DBH 9045 are shaft 10 mm, housing 25 mm and height 7.00 mm. The Lx configuration means a single sealing lip with a spring, held in a metal case. This is the usual setup for rotating shafts where the goal is to hold lubricant in and keep contaminants out. Because the lip contacts the shaft with slight interference, shaft finish and concentricity have a direct effect on how long the seal lasts.

You will find this seal in gearboxes, centrifugal pumps, low-power electric motors, conveyor rollers and belt or chain drives. It also appears in machine tools, compressors and low-pressure hydraulic systems. In each case, the seal is pressed into the housing and runs against the rotating shaft, shielding bearings and lubricant from particles.

When selecting the seal, confirm that the shaft diameter falls within the recommended tolerance for radial seals, that the housing bore and depth are correct, and that the shaft's peripheral speed stays within the limit of the lip material. Install it with a press tool, lubricate the lip and avoid impacts that could harm the spring. If the shaft is worn, a seal with an auxiliary lip may be a better fit.

For an equivalent or a different size, send part number 9045 or your current dimensions (shaft, housing and height) by WhatsApp or email. We can look for the next size up or down in the DBH line or suggest a seal from another brand that does the same job. We can also help you choose a lip material based on the fluid and operating temperature.
