Installation protocol:
Mount using M8×1.25 mounting screws (20 N·m torque limit). Perform 5-10 test strokes before full operation.
For vertical installations, orient adjustment screw upward. Relubricate every 500,000 cycles using ISO VG22 hydraulic oil.
Critical parameters:
Max lateral load ≤15N, axial misalignment tolerance ≤0.5mm. Not suitable for corrosive gas environments or
applications with continuous side impact forces. Requires annual oil replacement in 24/7 operations.
