The DBH 9867/85 is a radial shaft seal that keeps lubricant where it belongs and blocks dust, water and other contaminants from reaching the bearing. It fits rotating shafts in gearboxes, pumps, electric motors, gear reducers and compressors. This model uses the A 323 design and carries a shaft size of 27 mm, a housing size of 36.80 mm and a height of 3.50/6.50 mm. MR supplies it as part of its seal range.

Reading the 9867/85 code: the seal belongs to the DBH line, and its measurements are shaft 27 mm, housing 36.80 mm and height 3.50/6.50 mm. The A 323 configuration is a single lip with a spring, which keeps the lip pressed against the shaft as it turns. The stepped height helps the seal seat firmly when the housing has a shoulder. Elastomers used in this type of seal resist oils and greases.

Where it works: gearboxes, pumps, electric motors, gear reducers and compressors all rely on this kind of seal at the point where the shaft exits the housing. In dusty or damp conditions, the seal protects both the lubricant and the bearing, which affects how long the assembly lasts. A worn seal can let grease escape or let grit in, so it is worth checking during maintenance.

Installation notes: clean the shaft and housing first, removing any burrs. Put a light film of the same oil or grease used in the equipment on the lip. Press the seal in squarely, using a tube or socket that contacts only the outer edge, and never hit the lip directly. The lip should face the lubricant side. If the shaft is worn, look at a seal with an auxiliary lip.

Need a match: send the part number 9867/85 or the three dimensions (shaft, housing and height) through WhatsApp or email. MR can check alternatives within the same series or from other brands it carries, and can suggest the most suitable design based on shaft type and operating conditions. The more details you provide, the closer the recommendation will be.
