Code 5131 from DBH covers a radial shaft seal of the lip type, sized for an 11 mm shaft, a 30 mm housing bore and a 10.00 mm height, built to the Lx design. Its job on a machine is straightforward: hold oil or grease where it belongs and keep dust, water and particles out of the bearing cavity. MR Industrial Accessories supplies this seal within its line of seals and oil seals, and can help you confirm the size before you order.

Reading the code is the fastest way to check a replacement. The 5131 number identifies the seal in DBH catalogs and cross-reference tables, while the three measurements tell you where it fits: shaft (d) 11 mm, housing (D) 30 mm, height (h) 10.00 mm. The Lx design means one sealing lip on a metal body, a common choice for rotating shafts that need a dependable barrier against lubricant loss.

Small electric motors, reducers, centrifugal pumps, compressors and gearboxes are the usual homes for a seal this size, and the same dimensions turn up in agricultural equipment, power tools and lubrication systems where radial space is tight. In every case the seal does two things at once: it keeps lubricant inside the assembly and keeps contaminants out, which is what protects bearings and bushings from premature wear.

Installation decides how long the seal lasts. Confirm the shaft hardness and surface finish, and make sure the housing bore is clean and free of burrs. Seat the seal with the lip facing the lubricant side, driving it in with a tube or press that contacts the outer diameter only, never the lip. Coat the lip with the same oil or grease the equipment runs before you slide it into place. If the shaft surface is worn, a version with an auxiliary lip is worth considering.

When you need an equivalent, send code 5131 together with the shaft, housing and height measurements. Alternatives from other brands or with a similar design can be checked if the Lx configuration does not match your application, and the choice can be matched to the equipment type and the conditions it works in.
