Replacement Parts for Lincoln ORSCO Chain Lubrication
ORSCO is a Lincoln Industrial chain lubrication product line. These are aftermarket replacement parts, not manufactured, sponsored, or endorsed by Lincoln. ORSCO and Lincoln part numbers are for cross-reference identification only.
This page covers replacement injectors, nozzles, metering valves, pump components, and controller parts for existing ORSCO installations. The parts here mate with VS and VSR pumps, Series 170 pumps, 4 L and 16 L reservoirs, and the SWN, TPN, TFN, TCN, and HSA-TD nozzle families. Every listing is a service part for a working multi-point oil spray system, not a new complete system package.
Replacement injectors are fixed-displacement positive displacement units that meter 15 mm3 or 60 mm3 per stroke. Each nozzle is fed by one dedicated injector. Components are selected by line configuration, nozzle type, reservoir size, and controller voltage.
For questions about interchange, thread size, or controller compatibility, contact the team through the quote page.
What ORSCO Systems Do
An ORSCO system is an air-operated multi-point oil spray system with fixed-displacement injectors. The pump pressurizes oil from a transparent tank, and individual injectors meter a set volume per stroke. Compressed air at 5 to 7 bar moves the oil from each injector to its nozzle.
Output is either pulsed or continuous. Pulsed mode meters 15 mm3 per stroke with a minimum cycle time of 0.5 s. Continuous mode supports 15 mm3 or 60 mm3 per stroke depending on injector selection. One pump can serve 2 to 8 outlets on VS and VSR pumps, or up to 16 outlets on a Series 170 pump.
The system applies a metered oil film directly to chain links, rollers, pins, or slide surfaces. Lubricant line length is 7.5 m in pulsed mode and 15 m in continuous mode. The transparent reservoir includes an output filter and is available in 4 L or 16 L capacity.

The pump body mounts upright only. Viscosity handling is 20 to 400 cSt for standard builds, with special applications possible up to 9,200 cSt. Actuation is up to 1 Hz per injector, with a combined output of 4 drops per second across the bank.

Nozzle Families
| Model | Type | Application | Connections |
| SWN | continuous spray | general chain lubrication, inline or low-profile | air 1/4 in or 6 mm, oil 3/16 in or 4 mm |
| TPN | pulse | high-speed chains, synchronized to chain pitch | air 6 mm, oil 4 mm |
| TFN and TCN | specialty pulse | tenter frames, wide chains | application-specific |
| HSA-TD | monitored | applications needing switch feedback | bracket options |
SWN nozzles mount inline or low-profile and produce a continuous spray. TPN nozzles operate in pulse mode for high-speed chains and synchronize output to chain pitch. TFN and TCN are specialty pulse nozzles for tenter frames and wide chains with application-specific connections.
HSA-TD is a monitored nozzle with switch feedback. Bracket options vary by mounting surface and chain access. Air and oil connection sizes are listed in imperial and metric where applicable.

Matching Nozzle to Chain Speed
| Chain speed | Mode | Output | Nozzle |
| below 1 pitch per second | pulsed | 15 mm3 per stroke | TPN |
| above 1 pitch per second | continuous | 15 or 60 mm3 per stroke | SWN |
| extreme high speed | continuous | 60 mm3, multiple injectors | SWN |
Chain speed is measured in pitches per second, not meters per minute. Below 1 pitch per second, TPN pulse output gives a discrete charge per pitch. Above 1 pitch per second, SWN continuous spray delivers a steady film.
Extreme high speed uses 60 mm3 continuous output through multiple injectors and SWN nozzles. Each nozzle still has one dedicated injector. The synchronization rule prevents skipped links on slow chains and dry spots on fast chains.
What to Confirm Before Ordering
Confirm the pump family first: VS, VSR, or Series 170. Outlet count must match the number of lubrication points. A VS or VSR pump supports 2 to 8 outlets, while a Series 170 supports up to 16.
Confirm injector metering volume because 15 mm3 and 60 mm3 injectors are not interchangeable without recalibrating output. Confirm nozzle family from the existing installation. SWN, TPN, TFN, TCN, and HSA-TD use different line connections and brackets.
Confirm oil viscosity, because standard operation is 20 to 400 cSt. Confirm air supply pressure between 5 and 7 bar. Confirm controller power as 115 VAC, 230 VAC, or 24 VDC before ordering a replacement controller or solenoid component.
Confirm lubricant line length. Pulsed mode is rated to 7.5 m and continuous mode to 15 m. Longer runs require moving the pump or rebalancing injector placement.

Frequently Asked Questions
Will these parts fit my existing ORSCO system?
Fit depends on pump family, outlet count, nozzle type, and line connection size. Confirm these four details before ordering any replacement part.
Is this an original Lincoln ORSCO product?
No, these are aftermarket replacement parts for existing ORSCO installations. ORSCO and Lincoln names are used for cross-reference identification only.
What metering volumes do the injectors deliver?
Standard injectors meter fixed volumes of 15 mm3 or 60 mm3 per stroke. Adjustable metering of 13, 15, or 60 mm3 is available on request.
Which nozzle suits a fast-moving chain?
Chains above 1 pitch per second use SWN continuous spray with 15 or 60 mm3 per stroke. Extreme high speed combines 60 mm3 output with multiple SWN injectors.
Can the system spray grease instead of oil?
No, the pump and injectors are built for mineral, synthetic, or biodegradable oil only. Grease will not meter correctly through these fixed-displacement injectors.
What oil viscosity can it handle?
Standard operation covers 20 to 400 cSt at operating temperature. Special applications may run up to 9,200 cSt with specific injector and line configuration.
How many lubrication points can one pump feed?
VS and VSR pumps feed 2 to 8 outlets, and Series 170 pumps feed up to 16. Each point requires one dedicated injector and nozzle.
Does the pump need compressed air?
Yes, the system is air-operated and requires a supply pressure of 5 to 7 bar. Air consumption per nozzle varies with installation and is not fixed.
What controller power options are there?
Replacement controllers are available in 115 VAC, 230 VAC, or 24 VDC. Match the voltage to the existing installation nameplate before ordering.
