Zero-Max Keyless Connections - ETP and Posi-Lok

Keyless connections are locking devices for shaft-to-hub connections for positioning and locking shaft components, and for synchronizing moving parts. The Zero-Max design eliminates keyways and tapers that weaken or cause excess wear to the shaft.

  • A solid connection between the shaft and mounted device using a simple, friction grip that doesn't require keyways.
  • Nickel plated finish protectr from contact with corrosive substances. (Stainless steel available upon request)
  • Socket-head cap screws tighten quickly and easily.
  • Excellent axial and radial runout.
