Features & Application

Features & Application

  • Multipurpose
    Ideally structured and highly reliable locking device
  • Low Machining Costs
    Keyway, splines, presses and thermal fittings are not required. Optimum performance is achieved with low shaft and hub tolerances minimizing the total machining costs.
  • Easy to Install
    Install or removes just by tightening or loosening of bolts. No need to hassle with adjusting keyways and thermal fittings.
  • Options to Fit Every Application
    Stainless Steel and electroless nickle plating options are offered for standard models. Both are highly durable in corrosive or clean room environments.
