Installation guidelines:
Requires horizontal mounting for optimal performance. Use 4×M24 class 8.8 bolts
(torque 600N·m) for flange mounting. Lubricate with ISO VG32 hydraulic oil
during initial commissioning. Allow 100mm clearance behind rod end for maintenance.
Critical note:
Maximum side load capacity 1,500N. For angular misalignment applications,
must install KA-250 rod-end spherical bearing kit (sold separately).
