Applications

Up to ~300 points

Slideways, spindle bearings, ballscrews and rotary tables, each fed a fixed dose per cycle regardless of pipe run or pump pressure: the point-count and precision that made volumetric distributors the standard here. See the full CNC & machine tool lubrication page.

Under ~20 points

Smaller machines with fewer lubrication points, where a resist-type distributor meters oil or grease by flow resistance rather than a piston: simpler, and sized for light-duty equipment. For the clamping unit of an injection moulding machine specifically, see that page.

Varies by machine

The original application these distributor designs were built for. Spindles, rollers and bearings across a production line, on both resist-type and volumetric systems depending on point count. See the full textile machinery lubrication page.

1–200 points

Pins, bushings and slew rings under high load, supplied in sequence through a progressive distributor rated to 25 MPa: grease-only, and built to keep running under shock loading. See the full construction machinery lubrication page.

Step chains, guide rails & door gear

Guide rails, step chains and door mechanisms that need a steady, metered feed rather than periodic manual greasing. Factory-fitted by escalator OEMs and retrofitted in service. See the full escalator lubrication system and lift guide rail pages.

Slides, gibs & ejector gear

Forging presses, punching and stamping lines, where slideways and gibs take shock loading and a manual grease gun cannot keep up. A progressive system feeds every point in a fixed sequence and stalls visibly if one is blocked, which is what makes it the usual choice where a missed point means a scrapped die. See the full forging & metal forming lubrication page.

12 / 24 V DC, on-vehicle

Chassis pins, bushes, spring shackles and fifth wheels on tippers, trucks and buses. These pumps run straight off the vehicle’s own 12 V or 24 V supply and carry a vehicle-mounted controller, so lubrication happens while the vehicle works rather than waiting for it to come back to the yard. See the full vehicle chassis lubrication page.

Main, yaw & pitch bearings

Inside the nacelle: the main bearing, the yaw and pitch bearings and their gear faces, and the generator bearings. Points that sit a long climb away from anyone who could grease them by hand, on a machine that has to keep turning, so the pump runs to a schedule and reports low level and blockage back down the tower. See the full wind turbine lubrication page.

Small & medium equipment

Bearings and gear faces on smaller equipment where a compact manual or motor-driven grease pump covers the whole job without a full distributor network. See the full general industrial machinery lubrication page.
