SKF centralized lubrication system components

Every code here is a manufacturer part number. Looking at LL/352-005-VS or LL/24-0404-2337 will not tell you what the part is or what it delivers; the code simply points to one specific component. Others, like LL/DDC-222 and LL/DCM-20, belong to a family of parts and use a number to show the size or variant.

So copy the full code from the component nameplate or the system parts list, including the slash, the hyphens and any letters at the end. A one-digit difference can mean a metering device with another output or a fitting with another thread. If the nameplate is unreadable, the part number can be worked out from the system type and the details of the part.

Systems come in single-line, dual-line and progressive designs, and parts from one design do not work in another. In a progressive system the feeders dispense lubricant in sequence, so one blocked point stops the rest. In a single-line system each metering device delivers its dose when the line is pressurized and then vented. Once you know which design the machine uses, the search falls into place.

When a point is not getting lubricant, the problem is usually upstream: a broken hose, a loose fitting, air in the line, a stuck metering device or an empty reservoir. Check what reaches each section before you order a spare. The lubricant also matters, since some greases do not pump well through long, narrow lines.

Send the full LL part number and the quantity, plus the pump make and model, the system type, how many points it serves and the lubricant it runs. For a metering device or feeder, include the number of outlets and the output marked on the part. For a fitting or hose, include the thread, tube diameter and length. A photo of the nameplate and another of the part in place make identification easier.
