Installation note:
Ensure alignment tolerance ≤0.2mm/m during mounting. For adjustable stroke applications,
always lock the adjustment screws with 3.5N·m torque after positioning. Use M6x1.0 mounting
bolts (grade 8.8 or higher) for structural integrity.
Maintenance alert:
When using in dusty environments, install rod boot SC-63A (sold separately) to prevent
abrasive particle ingress. Lubricate every 500km of cumulative travel with ISO VG32
turbine oil.
