Selecting the Proper Screw

Ball Screw Advantages

Ball Screw with Deflector

 

  • Improves speed, force, and duty cycle
  • Longer and predictable life cycle
  • Requires less motor power
  • Heavier loads
  • Greater accuracy
  • High efficiency (less friction)

Acme Screw Advantages

Acme Screw

 

  • Preloaded nut assembly eliminates backlash
  • Safe to operate under static load to hold
  • Self-locking - no need for brakes (even in power outage)
  • Low noise (no rolling components)
  • Ideal for vertical and light/moderate loads
  • Eliminates backlash
  • Lower cost solution

Roller Screw Advantages

Roller Screw

  • Highest efficiency rolling motion
  • Carry large loads with very high resolution
  • Small axial movement (even with very shallow leads)
  • High rotational speeds with faster acceleration
  • The most reliable screw solution available
  • Higher cost option with highest performance
