Koganei Alpha Series Twin Rod Cylinders B Series Double Rod Type

Manufacturer: KOGANEI CORPORATION

Features

Linear ball bearings are used for the rod bearing.
The use of linear ball bearings for the rod bearing and high carbon chrome bearing steel for the piston rod assures high rod end deflection precision even during full strokes. In addition, this eliminates bearing wear and maintains the initial inherent accuracy.

Two rods achieve non-rotating accuracy of ±0.1°.
Rational construction features 2 piston rods that prevent rotation and work together as guides.

Stopper bolt allows for stroke adjusting even after mounting.
Adjusting the stopper bolt makes stroke adjustment possible within a range of −5〜0 mm [−0.197〜0 in.] (one side). Boosts operating efficiency when mounting and adjusting.
