A rotary lip seal from the DBH line, the 6112Pol keeps oil or grease inside a housing while blocking dust, water and particles from reaching the bearing area. Its Mx-R H configuration combines an elastomeric lip with a metal outer case, so it presses into the bore and rides against the shaft surface. The three figures that define the fit are shaft 31.70 mm, housing 44.60 mm and width 6.70 mm. Typical duty is a shaft turning at moderate speed where a compact, low-friction barrier is needed.

Reading the code helps when you compare it against what is currently installed. The 6112Pol belongs to the DBH seal family, and the Mx-R H designation describes the lip geometry and case style rather than a size. Because the numbering is separate from the dimensions, always confirm the three measurements before ordering: d = 31.70 mm at the shaft, D = 44.60 mm at the housing bore, and h = 6.70 mm across the section.

You will find seals of this type in gearboxes, pumps, electric motors, transmission shafts and process machinery, as well as in machine tools and linear motion units that call for a slim sealing element. Service conditions in food, chemical and materials handling plants are common, as long as the lip compound suits the fluid being retained and the temperature at the sealing point.

Installation decides how long the seal lasts. Check that the shaft sits within the recommended tolerance and that its surface is smooth and free of grooves or scoring. The bore needs the right diameter and enough depth for the 6.70 mm section so the lip is not crushed. Coat the lip with the same oil or grease the equipment runs on, drive the seal in with a tube that bears on the outer case only, and keep the assembly concentric. Striking the lip or cocking the seal during fitting usually leads to leaks.

For a quote, send the code 6112Pol through WhatsApp or email, ideally together with the shaft and housing measurements you have on hand. We work through the DBH seal range and can also suggest equivalents where the Mx-R H design is not the only option, matching the mounting dimensions and the fluid involved.

MR Industrial Accessories supplies the DBH brand within its seals and radial shaft seal range and serves customers throughout the United States and in several Latin American countries. If you are unsure of the size, share your shaft and housing diameters and we will help you identify the correct seal.
