Yoder M-Series Roll Forming Systems are one of the most popular and copied mill stands in the world. Highlights of these systems include:
- Drive housing encloses all gears in oil tight case.
- Precision Timken tapered roller bearings (inboard side).
- Roller bearings, rotating in hardened sleeves (outboard side).
- Features toggle-link gear train to maintain full gear mesh through entire top roll shaft adjustment.
- Outboard housing removable from ends of roll spindles and adjustable laterally on spindles. This permits most advantageous support of roll shafts during forming of narrow sections.
- Alloy steel roll spindles, carburized, hardened, and ground.
- Hardened hex-type clamping nuts.
- Micrometer screws to facilitate accurate adjustment of spindles after roll changes.
- Toggle-type idler gears permit maximum roll adjustment but maintain constant gear mesh.
