How zero-backlash roller racks enable fast long-travel axes
Multiple rollers engage the trochoidal tooth profile at once, reducing backlash, noise, vibration and dust.
TECHNICAL KNOWLEDGE
Technical explanation
In the TCG system, bearing-supported rollers run on a trochoidal tooth profile, typically maintaining two or three contact points.
Standard sizes 1008A-4014A provide 80-560 mm travel per revolution and can be joined into long axes.
Catalogue ratings span 130-14,000 N dynamic and 200-21,000 N static; final selection must still account for speed, load cycle, mounting stiffness and life.
