Installation note:
Lubricate rod with ISO VG32 hydraulic oil before initial operation.
Ensure alignment tolerance ≤0.2mm/m to prevent side load.
For full stroke applications, allow 15mm extra clearance at both ends.
Critical parameters:
Max lateral load 850N, axial load 12kN.
Maintain air filtration at 40μm or finer.
Cycle rate ≤85% of theoretical maximum in continuous operation.
