For rotating shafts that need a dependable barrier against lubricant loss and outside contamination, the DBH 1106 oil seal is a radial labyrinth-type seal. It measures 133.35 mm at the shaft, 187.33 mm at the housing and 25.40 mm in height, and it carries the 1106 designation with an A 247 design. MR Industrial Accessories LLC supplies this seal for industrial maintenance and repair work.

Reading the number helps when you are matching a replacement. The 1106 code identifies the seal, while A 247 tells you it is a single-lip, spring-loaded design. The three dimensions to check against your assembly are shaft 133.35 mm, housing 187.33 mm and height 25.40 mm. That combination fits standard housings, and the 25.40 mm height lets the seal sit in deeper cavities without extra shims.

This seal is built for rotating shafts running at moderate speeds with controlled lubrication. It keeps oil or grease where it belongs and blocks dust, water and chips from reaching bearings and gears. You will find it in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment, including agricultural machinery, mining equipment and continuous process lines.

Selection starts with the shaft and housing. Confirm both dimensions match the assembly, and check that the shaft surface has the right hardness and a fine finish, since that affects how long the lip lasts. During installation, coat the lip with the same oil used in the equipment and keep burrs or sharp tools away from it.
