The innovative Tru-Change coupling ring set is the optimum coupling device for indexing or power transmitting applications. The curved tooth design provides full flank tooth interface between two coupling halves with 2 tenths (5 micron) repeatability. The result is an exceptionally high torsional load capability with self-centering and zero backlash as added benefits. Other unique features include:

Self - Improving Repeatability through continuous seating of coupling halves. Constant matching of teeth in mesh offer angular repeatability of .00005 (1 micron) which improves with use.

Full Radius Tooth Tips provides quick and assured coupling engagement.

High Number of Teeth allow angular indexes of less than one degre with a +/- 3 second true position.

Highlights:

• Capable of 5 micron repeatability
• High torsional load capacity
• Patented curved tooth design
• Self centering and zero backlash
• Adaptable to any fixture or workholding device
