The DBH 5316 is a radial shaft lip seal that sits in a housing and keeps lubricant where it belongs while blocking dust and water from reaching the bearing cavity. Its designation reads 30x42x7 mm: 30.00 mm shaft, 42.00 mm housing bore, 7.00 mm height. The Lx design refers to the lip and body configuration of this seal. MR Industrial Accessories LLC supplies this brand and can help you confirm the right part for the shaft you are working on.

Seals like this one show up on gearboxes, pumps, electric motors, conveyor rollers and other power transmission assemblies. The job is simple to describe: hold the oil or grease in, keep contaminants out, and protect the bearings and gears behind it. Because it is a wear part, it belongs on the preventive maintenance checklist. Replace it whenever you find leakage, a hardened lip or visible damage.

Reading the code helps when you order. The 5316 identifies the item; the three figures give shaft, housing and height in that order. For material, tolerance and temperature limits, ask for the manufacturer's data sheet. Send the code with your shaft and housing measurements and a photo of the old part, and we can look for alternatives in other brands or configurations in the same category.

Installation decides how long a seal lasts. The shaft and bore must be clean, with no burrs or scratches, and the measurements have to match the seal. Put a light film of lubricant on the lip before you press it in, and drive it with a tube or press that contacts the outer diameter, never the lip. If the shaft is worn, an auxiliary lip may be the better choice. Speed, temperature and the fluid being retained all affect the final selection.
