Ball Screw and Lead Screw Assemblies

Both technologies use self-lubricating nuts for maintenance-free performance

Ball screw and lead screw linear assemblies, defined as precision guides that can be equipped with NEMA motors, hand cranks, or left unmotorized for custom linear motion control. Ball screws utilize recirculating steel balls within cylindrical or flanged nuts, offering superior speed, durability, and short lead times through precise rolling action that maintains consistent lead accuracy across the screw's length. Lead screws, by contrast, deliver a more cost-effective option with Round or Triangular Constant Force Anti-Backlash Nuts, which are incompatible with ball screw systems, exhibiting 2-4 times less backlash than competitors over their lifespan. Both technologies benefit from self-lubricating nuts, ensuring reliable, maintenance-free performance in demanding environments.
