Designed for Stability. Built to Last. Trusted to Perform.
Key Features of Our COE Systems
Wobble-Free by Design
Our precision chain and track system maintains spindle stability and concentric rotation without relying on chain tension. This ensures smooth, consistent motion—even with tall, heavy, or off-center parts.
Heavy-Duty Options
From small fasteners to 200 lb components, our COE line includes 1.5” to 4” pitch systems with load capacities up to 200 lbs per spindle.
Stable, Enclosed, Self-Cleaning Track
Modular, boltable track sections ensure precise alignment and allow for future expansion or reconfiguration. The enclosed design keeps the system protected and reduces maintenance.
V-Load Wheel Support
Spindle loads are guided by ball-bearing, self-cleaning V-load wheels that provide smooth, consistent motion and minimize debris buildup—ideal for harsh coating environments.
Versatile Spindles & Fixtures
Rotating, non-rotating, and detented spindles are available. Fixtures can hold single or multiple parts per spindle and can integrate built-in spray masking for efficient processing and overspray protection.

Common Alternatives—and Their Limitations
Slide Plate Design (By Others)
These systems use hollow pin chain with oversized rollers and spindle pin mounts made from flat plates. The plates slide on wear strips mounted to the top of the conveyor track. In painting applications, these wear strips quickly accumulate overspray, leading to increased friction, inconsistent motion, and accelerated wear. These systems are typically limited in spindle load capacity, chain length, accuracy, and overall stability—making them unsuitable for precise or high-production applications.
Exposed Cart Design (By Others)
These systems use hollow pin chain with oversized rollers and spindle mounts built into four-wheel carts that ride directly on top of the conveyor track. The carts typically use solid wheels—not self-cleaning V-load wheels—resulting in poor debris handling, erratic tracking, and limited stability. Overspray quickly builds up on the exposed track surface, increasing drag, causing inconsistent movement, and requiring frequent cleaning. These systems struggle with tall, unbalanced parts and offer little consistency in high-precision applications.
Overhead as COE (By Others)
Repurposed overhead conveyor components are often flipped and used on the floor for chain-on-edge applications. However, they lack the rigidity, load support, and spindle control needed for precision finishing. The result is frequent wobble, misalignment, and high maintenance demands.
All three of these designs share a critical flaw: the spindle rotation point is fully exposed above the track. There is no structural support above the rotation point, meaning spindle stability is often driven by chain tension alone. This results in poor rotational consistency and minimal lateral stability. In many cases, it also presents a safety hazard, especially in automated environments with tall or heavy parts.
Copycat COE Designs
Some systems attempt to mimic Precision Conveyor’s design elements—but lack the 35 years of engineering expertise, field experience, and continuous development that go into every one of our conveyors.
Why Precision Conveyor Systems Lead the Industry
We don’t just build conveyors—we engineer long-lasting solutions that perform in the real world. With over 35 years of experience, our chain-on-edge systems are trusted by manufacturers who need stable part handling, low maintenance, and dependable operation in high-contamination, high-demand coating environments.
Built on Experience
Every system reflects decades of coating system design, hands-on fieldwork, and continuous improvement.Support You Can Trust
From concept to startup, we stand behind every system we deliver—with real engineering, not guesswork.
