Roller gearing is a new technology that uses balls/rollers to transmit torque and the rollers carry out pure rolling motion.

Special advantages include very high efficiency (94-98% ), no back-lash, high contact factor (10-20).

Applicable for any gears, any geometry, axes angles, offsets, ratios, torque and power, speed, application etc. Specially applicable for high ratios and complex geometries - still performing at very high efficiency. Roller worm gears efficiency is also very high, well above 90%.
