Model 190LSE
Line Shaft Photo Eye Zero Pressure Accumulating
Air operated zero pressure accumulation with photo eye control on line shaft drives.
View Specs →About Line Shaft TechnologyOne motor drives a longitudinal shaft the full length of the conveyor. Urethane O-rings transfer drive to each roller. When an O-ring breaks, replace it in seconds — no chain or belt removal required. Significantly lower maintenance cost for long straight runs. Includes curve and spur sections for complete system layouts.
The Fundamentals
How Does a Line-Shaft Conveyor Work?
A line-shaft live roller conveyor uses one longitudinal drive shaft beneath the conveying rollers. Urethane O-rings transfer power from that shaft to individual rollers, allowing one drive arrangement to power a series of straight, curve, and spur sections.
The platform is commonly evaluated for compatible cartons, totes, and unit loads with stable bottoms. Its modular routing options and accessible O-ring drive components can make it a practical choice for packaging, distribution, and other light- to medium-duty transport layouts.
The ACSI family includes a straight 190LS conveyor, 190LSC-series curves and spurs, and the photo-eye controlled 190LSE for zero-pressure accumulation. Product support, load, rate, line length, curves, accumulation, and operating environment determine the final configuration.
Straights and Curves
Combine straight sections, curves, and spurs to route compatible unit loads through a system.
Accessible Drive Parts
Individual O-rings can be serviced without removing a full-length chain or drive belt.
Accumulation Option
The 190LSE adds photo-eye controlled, air-operated zero-pressure accumulation.
Application Guidance
When Line Shaft Fits.
Evaluate the product, route, control requirements, and operating environment before choosing a line-shaft platform.
Compatible Unit Loads
Cartons, totes, and cases need stable bottoms that receive adequate support from the selected roller centers.
Starting point: Product base and weight
Routing Requirements
Identify straight runs, curves, spurs, merges, and discharge directions before selecting powered sections.
Starting point: 190LS and 190LSC family
Accumulation Needs
If products must queue without contact pressure, define zone length, controls, release logic, and downstream conditions.
Starting point: 190LSE
Buyer Questions
Line-Shaft Conveyor FAQs.
Answers to common questions about the drive system, suitable products, routing, and accumulation.
How does a line-shaft conveyor drive its rollers?
A longitudinal drive shaft runs beneath the rollers, and urethane O-rings transfer power from that shaft to individual rollers.
What products are suited to line-shaft live roller conveyor?
Line-shaft conveyor is generally considered for compatible cartons, totes, and other unit loads with stable bottoms that can be supported across the selected roller centers.
Can line-shaft conveyor include curves and spurs?
Yes. ACSI line-shaft models include curve and spur sections for routing and branching compatible unit loads.
Can line-shaft conveyor provide zero-pressure accumulation?
Yes. The ACSI 190LSE uses photo-eye control and air operation to provide zero-pressure accumulation on a line-shaft platform.
