When a rotating shaft has to keep lubricant inside the housing and dirt outside, the DBH 5142Sil radial shaft seal is the part that does that job. It is built for a 38 mm shaft, a 72 mm bore and a 12.00 mm height, and its Lx design tells you it uses a single lip with a spring. MR Industrial Accessories lists this seal in its seals and oil seals range.

Reading the code helps you confirm the fit before you order. The 5142Sil designation carries the size information: d = 38 mm for the shaft, D = 72 mm for the housing bore and h = 12.00 mm for the height. The Lx suffix points to a single lip with a spring, a common choice for rotating shafts. The elastomeric lip wipes the shaft surface while the metal outer case presses into the bore to hold the seal in place.

Seals in this size range turn up in gearboxes, pumps, electric motors, rollers and other transmission equipment where a shaft spins inside a housing and oil or grease has to stay put. They are also used where dust or splashes are present and the lip has to block contaminants. In plants, repair shops and maintenance programs, this is a wear item that gets swapped out whenever the equipment is opened.

Installation is straightforward but the details matter. Clean the shaft and the bore, remove burrs or marks, and put a light film of lubricant on the lip before you press it in. Keep the seal square to the shaft and apply force evenly on the outer case, never on the lip itself. If the shaft surface is worn, consider a seal with the lip positioned differently or a repair sleeve. Speed, temperature and the fluid being retained all affect the final choice.

If you are matching an equivalent, send the code 5142Sil or the shaft, bore and height measurements of the original seal. With that information we can check alternatives in the DBH line or in other brands we supply. We can also tell you whether the Lx design fits your application or whether a different lip style or material would be better.
