Installation tip:
Maintain 0.5-1mm alignment tolerance during mounting. Lubricate with ISO VG32 hydraulic oil
if operating below 1 cycle/minute. Avoid side-load exceeding 15N during operation.
*Full stroke tolerance varies with mounting orientation - add 0.2mm compensation for vertical downward installations
