Measuring 8 mm at the shaft, 22 mm at the housing bore and 7 mm in height, the DBH 9036 is a single-lip radial shaft seal built for small rotating shafts. Its Lx configuration keeps oil or grease inside the assembly while blocking dust and water at the point where the shaft leaves the housing. Compact motors, pumps, gearboxes and similar transmission equipment are the usual homes for this size.

Reading the code is straightforward: the three figures in the designation follow the standard order of bore, outside diameter and width, which is why the seal is listed as 8 x 22 x 7 mm. Lx identifies a single sealing lip with a spring, a design meant for shafts turning in one direction under permanent lubrication. The lip flexes against the shaft to absorb minor misalignment, and the outer body holds the press fit in the housing.

You will find this size in low-power electric motors, small centrifugal pumps, worm gearboxes, fans, mixers and other transmission units that carry oil or grease. Pneumatic tools and laboratory or dosing equipment also use it, since an 8 mm shaft is common there and lubricant loss or outside contamination has to be prevented.

Installation decides how long the seal lasts. Check that the shaft diameter sits inside the recommended tolerance and that the running surface is smooth, with no burrs or grooves. The housing bore should be clean and undamaged. Drive the seal in with an installation tube that presses on the outer edge, never on the lip, and coat the lip with the same oil or grease the equipment uses beforehand. Play or eccentricity on the shaft keeps the lip from seating evenly and shortens service life.

For a quote, send the 9036 number along with the 8 x 22 x 7 mm dimensions on WhatsApp. We check the DBH line or another brand we carry and confirm the data against the manufacturer's sheet. When the shaft shows heavy wear, a spring-loaded lip or a version with extra dust protection may be the better choice.

MR Industrial Accessories supplies the DBH brand and also manufactures split plummer block housings, ANSI chains and sheaves. Send the part number and the quantity you need on WhatsApp and an advisor will review the application and come back with the option that fits your equipment.
