Built for the loads
that break ball rail.
Hevi-Rail is a cam-roller linear guide engineered for the heavy-duty, dirty, high-shock environments where recirculating-ball technology fails — lumber, mining, steel mill, heavy material handling. Long travel, big loads, contamination tolerance, and rebuildable in the field.

Why engineers spec Hevi-Rail
Cam-roller construction on a beefy rail profile — engineered for the abuse where ball rail's recirculating elements would jam, contaminate, or grenade outright.
Heavy load capacity
Cam rollers on hardened raceways carry per-roller loads measured in kilonewtons — the loads ball rail can't see.
Contamination tolerant
No recirculating elements, no ball cage to jam. Sawdust, chips, and grit ride past without taking the carriage out.
Long travel, joined rail
Rails join end-to-end for travels measured in meters — far beyond what a stock profile rail can deliver.
Field-rebuildable
Rollers swap out in the field with hand tools. No sending the carriage back to the OEM, no production downtime.

We were eating ball-rail carriages every [VERIFY] months in our sawmill. Switched to Hevi-Rail and the rollers have been spinning for [VERIFY] years.
Built heavy.
Run dirty.
Last longer.
