The DBH 9259 is a spring-loaded, single-lip radial shaft seal. It keeps lubricant inside the assembly and keeps dust and water out along a rotating shaft. With a 25 mm shaft, a 47 mm housing bore and a 13 mm height, it fits medium-sized pumps and transmission equipment. MR Industrial Accessories supplies it within its seals and oil seals range for industrial maintenance work.

Reading the designation helps with identification. The DBH 9259 is built to nominal dimensions of 25.00 mm shaft diameter (d), 47.00 mm housing diameter (D) and 13.00 mm height (h). The Lx design pairs a sealing lip with a spring that rides against the shaft with a metal case pressed into the housing bore. That combination suits 25 mm shafts in gearboxes, pumps and electric motors where oil or grease has to stay in and contaminants have to stay out.

You will find this seal in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment, as well as in machine tools and process equipment where a 25 mm shaft turns on bearings and the lubricant needs protection. Because it is a wear part, it is worth inspecting whenever you notice oil weeping, unusual noise or dirt reaching the seal area.

Before installation, confirm the shaft is clean and free of burrs or marks, and that the housing bore and depth match the seal. Lubricate the lip before pressing it in and avoid striking the seal during fitting. Shaft speed, operating temperature and the fluid being sealed all influence the choice; if the original part has a different height or design, an equivalent or close size can be found within the DBH line.

To replace a DBH 9259 or find another size, send the code, the shaft dimension, the housing diameter and a photo of the part by WhatsApp or email. The MR Industrial Accessories team will point you to the right option and prepare your quote, and can also check whether a seal with a different height or design suits your application better.
