Installation guidelines:
Maintain 0.5-1mm alignment tolerance during mounting. For vertical installations,
use MB2 mounting style with additional support brackets. Lubricate through port
with ISO VG32 hydraulic oil if operating below 0.3MPa. Allow 50mm clearance at
stroke ends for cushion adjustment.
