LS-300 Linear V-Track Optical Sorting Machine for Long Shafts & Heavy Bolts
LS-300 Linear V-Track Optical Sorting Machine with enclosed safety housing, industrial vision cameras and automated inspection control for long and heavy components.
LS-300 Linear V-Track Optical Sorting Machine Overview
The LS-300 Linear V-Track Optical Sorting Machine is designed for long shafts, heavy bolts, threaded rods and other components that are difficult to stabilize on conventional rotary glass disc sorting machines.
Instead of relying on a flat rotating disc, the LS-300 uses a precision-engineered V-track feeding and positioning system to keep long or heavy parts stable during optical inspection. Gravity-assisted feeding and precision synchronous belts help maintain consistent part positioning while industrial cameras capture dimensional, geometric, thread and surface information.
The system is particularly suitable for components where length, straightness, thread condition, head geometry and surface integrity must be checked automatically at production speed.
For manufacturers comparing different optical sorting technologies, the LS-300 is especially suitable when long parts are unstable on a conventional glass disc.

Why Choose a V-Track Optical Sorting Machine?
- Stable Part Positioning:Precision V-grooves help center long bolts, shafts and threaded components during imaging, reducing movement and positioning variation.
- Designed for Long Components:Suitable for parts that are difficult to stabilize on conventional rotary glass discs, particularly long shafts and heavy fasteners.
- Non-Contact Optical Inspection:Industrial cameras inspect dimensions, threads, geometry and surface conditions without mechanical contact with the inspection surfaces.
- Multi-Camera Inspection:Configurable with up to six high-resolution industrial cameras, depending on the inspection requirements of the part.
- Automated Defect Rejection:High-speed pneumatic blow-off or precision diverter systems can automatically separate detected NG parts from accepted components.

Linear V-Track vs. Rotary Glass Disc Optical Sorting
The main advantage of a linear V-track system is its ability to provide controlled support for elongated components. Long shafts and heavy bolts can become unstable when positioned on a conventional flat rotary glass disc, particularly when the part has a high center of gravity or a large length-to-diameter ratio.
A V-track system provides a defined mechanical guide for the component while it passes through the imaging area. This makes the LS-300 a suitable option when stable positioning and straightness inspection are important.
If your components are shorter, flat or naturally stable on a rotating glass surface, aGlass Disc Optical Sorting Machinemay be a better choice for high-volume applications.
For parts that require individual mechanical fixtures and indexed multi-station inspection, consider aRotary Indexing Plate Optical Sorting Machine.
Frequently Asked Questions
Why choose a Linear V-Track Optical Sorter for long bolts?
Long bolts and shafts can be difficult to stabilize on flat rotary discs. The V-track provides a defined support path that helps maintain consistent orientation and positioning during imaging, making it suitable for elongated and heavy components.
Can the LS-300 detect bending or straightness defects in shafts?
Yes. The system can be configured with lateral imaging and vision algorithms to evaluate shaft straightness against a defined reference axis and reject parts that exceed the specified tolerance.
What types of thread defects can the machine inspect?
Depending on the camera configuration and part geometry, the system can inspect visible thread damage, crushed threads, broken thread teeth, pitch-related deviations and thread depth.
What is the maximum part length supported?
The standard reference range is approximately 50–300 mm, while custom configurations can support longer components up to approximately 1000 mm depending on part geometry and system design.
Can the LS-300 inspect heavy steel bolts?
Yes. The LS-300 is designed for long and heavy metal components that require stable linear support during inspection. Final feeding, track and rejection configurations should be determined from the actual part dimensions, weight and production requirements.
