Overview
The Single Line Resistance Lubrication System (SLR) is a cost-effective and reliable centralized lubrication method that uses a single main line to intermittently deliver oil through fixed-resistance metering devices (also called restrictors) to multiple lubrication points simultaneously.
Key Features
- Simple and economical
Minimal components: pump, piping, and metering fittings. Ideal for small to medium-sized machines. - Low-pressure system
Suitable for low-pressure lubrication applications. - No moving parts in distributors
Uses oil flow resistance to control dosage – reduces wear and maintenance. - Fixed oil volume per point
Lubrication quantity is pre-set by restrictor size – not adjustable during use.
Advantages
| Benefit | Description |
|---|---|
| Cost-effective | Affordable and ideal for basic lubrication needs |
| Easy installation | Simple layout and minimal parts |
| Simultaneous supply | All points lubricated at the same time |
| Highly reliable | No moving parts, low failure rate |
