The DBH 9312 is a radial shaft seal built to keep oil or grease where it belongs and to block dust from reaching a rotating shaft. Its small envelope makes it a common choice for pumps, electric motors, gearboxes and light transmission assemblies. At MR Industrial Accessories we supply this brand and help you match the seal to your shaft and housing before you order.
Read the code and the size together. The 9312 designation points to a metric size in the DBH line, and the dimensions behind it are a shaft of 18 mm, a housing bore of 26 mm and a height of 7.00 mm. The Ls design means one sealing lip with a spring, which is the configuration used on lubricated rotating shafts. Before replacing a seal, compare these three figures with the drawing or with the part you are removing.
You will find an 18x26x7 mm seal in small centrifugal pumps, low-power electric motors, gearboxes and compact gear cases, as well as in fan shafts and light machinery. Washing equipment and portable tools also use this size where lubricant has to stay inside and contaminants have to stay out. In every case the lip runs against a rotating shaft while the outer diameter sits in a fixed housing.
Installation starts with the bore and the shaft, not with the seal. Confirm the 18 mm shaft and the 26 mm housing, and check that the housing depth accepts the 7.00 mm height. The shaft surface should be polished and free of burrs, and the housing clean and undistorted. Put a film of lubricant on the lip, then seat the seal with a press or a proper installation tool rather than by striking it. A worn shaft may call for a different design.
If you need a cross-reference for the DBH 9312, send us the shaft diameter, the housing diameter and the height, or simply the code marked on the old part. We can search other brands or standard sizes and advise on lip type and seal material based on the fluid and the operating temperature. For a quote, message us on WhatsApp with code 9312.
