LENA stands for LE – low energy, NA – noise absorption. Energy saving spindle LENA has been designed for the highest speeds with the main goal of achieving lower energy consumption.
recommended for speeds up to 30 000 RPM
for all material Ne30 and finer
for tubes up to 210mm
energy saving in the average of 4 - 6% thanks to reduced wharve dia and lesser friction of smaller bearings (both neck bearing and footstep)
the only spindle with 17,5mm wharve dia in the market
