Precision rails with needle roller assemblies

Benefits

  • Ultimate rigidity and load capacity
  • Best for heavy duty applications
  • Excellent motion accuracy

Features

  • Needle rollers also with ACSM option
  • Rail sizes up to large cross sections
  • Available in two precision classes
Needle roller assemblies are for heavy-duty applications requiring ultimate rigidity. Ewellix offers two series with needle rollers the LWM/V and LWRM/V. The LWM/V rails are also offered in ACSM version with Ant-Creeping-System. Rail guides with needle rollers provide maximum dynamic and static load carrying capacity. They are often used in grinding machines, presses and other machining tool applications.
