Single Line Lubrication System Application
How a Single Line Lubrication System Works
- Pump — manual hand pump, small automatic reservoir pump, or central station builds line pressure on a cycle timer.
- Main line — one primary tube (often 6–10 mm) feeds all branches.
- Metering — each bearing receives lubricant via a fixed orifice, adjustable restrictor, or single-line injector at the branch.
- Relief / return — on some oil systems, excess returns to reservoir; grease systems typically vent to point only.
Unlike progressive blocks, SLR does not require pistons to visit every outlet in strict sequence — each point is hydraulically independent via its restrictor.
SLR vs Positive Injector vs Progressive
| System | Delivery | Pressure | Best for |
|---|---|---|---|
| Single line (SLR) | Orifice / restrictor per point | Low–medium | Simple machines, many light points |
| Positive injector (PDI) | Cycling injectors, adjustable ml | Low–medium | Variable dose per point |
| Progressive (SSV) | Sequential pistons in one block | High (to 30 MPa) | Compact multi-point grease circuits |
| Dual-line (VSG) | Alternating lines, large plants | High | Steel, mining, long distances |
Deep comparison: PDI vs SLR.
Typical Components (IsoHiTech Supply)
- Pumps: hand grease pump, 2–4 kg auto pumps, trochoid / BSB electric pumps
- Metering: DL single injectors, adjustable metering units, ZV-B / 3000 dividers (where applicable)
- Distribution: pipe & tubing, clips, manifolds 2–12 outlets, M8/M10 fittings
- Accessories: brushes for chains, adapters PT1/8–1/4
Selection Checklist
- Count lube points and required ml/cycle per point.
- Choose grease NLGI or oil ISO VG; confirm pump compatibility.
- Set cycle interval (timer or machine interlock).
- Size main line for max simultaneous injectors + pressure drop.
- Plan clips and bend radius on long conveyor runs.
- Document restrictor sizes — wrong orifice is the #1 cause of dry or flooded bearings.
Industries (expand Section4)
- Chain lubrication — brush or sprocket injection; see chain OEM clearance for NLGI grade.
- Injection molding — tie-bar, hinge, and guide lubrication on 24/7 cycles; SLR lowers manual greasing labor.
- CNC / machine tools — linear guides and ball screws; pair with lightweight auto pump.
- Mining & construction — SLR on smaller subsystems; heavy circuits may need dual line instead.
- Rail — switch, coupler, and bearing points with scheduled SLR cycles.

Chain System
The chain is very popular in many production lines. Isohitech has many solutions for this system. We could provide the brush system or the extra gear-in-center.
Injection Molding Machine
As we all know, the injection machine is working 24 hours a day. The SLR system is very cheap for some hosts to prolong the machinery's time.
CNC toolings
CNC machinery has many screws and linear guides. So SLR system is adopted in this system.
Heavy Duty Equipment
Heavy-duty equipment, like mining and construction machines, often uses Single Line Lubrication Systems (SLR) to lubricate their moving parts.
Railroad Industrial
Railroad and locomotive equipment use Single Line Lubrication Systems (SLR) to lubricate their moving parts. The SLR system is used for critical parts. These include bearings, gears, couplings, and track switches. They need regular lubrication to work efficiently.
Steel Industrial
The steel industry uses Dual Line Lubrication Systems to lubricate its machinery. Proper lubrication reduces friction and wear on these components.
What's the advantage of the SLR system?
Single Line Lubrication Systems (SLR) offer several advantages over traditional manual lubrication methods. They provide precise, controlled lubrication. They reduce human error, increase equipment lifespan, and improve efficiency. They lower maintenance costs and enhance workplace safety. SLR systems are a cheap solution for lubrication in many industries. They boost productivity, reliability, and safety.
Automatic
The SLR system is always equipped the control timer.
Reduce the Maintance
Longer the equipment work cycle
Easy install
The system is very easy to fix on the equipment.
