Brand：NTH
ౠ MECHANISM FOR OPENING THE ARMS OF THE STEADY REST WITHOUT SPRINGS AND FREE FROM WEAR.AND ANTI-VIBRATION DESIGN FOR MACHINING.
OPTION OF LUBRICATION
Manual lubrication: Low cost solution for medium working conditions and low swarf.
Central lubrication: For heavy working conditions and high build up of swarf
Central lubrication oil and air: For heaviest cutting conditions with high built up of swarf,dust or coolant
OPTION OF LUBRICATION
Omatei rollers (precision class P05) specially developed for our Steady Rests
Special sealing ensures highest precision and service life
Standard equipment: 1 set of cylindrical rollers
💮
Option: Spherical rollers (for travelling Steady Rests)
