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.

Rails and cage types

LWRM/LWRV type

M/V modular range rails can be equipped with aluminium or plastic needle roller assemblies. They are dimensional wise interchangeable to LWR rails in size 6 and 9.

LWM/LWV type

M/V standard rails for needle roller assemblies in plastic or aluminium. Available in sizes 3015, 4020, 5025, 6035, 7040 and 8050 to cover most machine tool applications

LWM/LWV with ACSZ

M/V type rails with ACSZ (Anti-Creeping- System) for constant cage position and motion precision.
The rack and pinion design comes with an aluminium needle roller assembly.

LWN/LWO type

Same performance as LWM//V type rails with needle roller assemblies. N/O rails do have different outside dimensions to be interchangeable to competitor offers.

End pieces

LWERM/LWERV

Standard end pieces for both M and V rails to be used in conjunction with LWRM/LWRV rails.

LWEARM/LWEARV

Standard end pieces with efficient wipers for both M and V rails to be used in with LWRM/LWRV rails.

LWEM/LWEV

Standard end pieces for both M and V rails to be used in combination with LWM/LWV rails.

LWEAM/LWEAV

Standard end pieces with efficient wipers for both M and V rails to be used in combination with LWM/LWV rails.
