Journal Bearing Actuators
Standard MP actuators utilize a journal bearing made of an advanced composite material that is filament wound and PTFE lined. Additional precision engineered components include high performance seals for shaft, shoulder, vane and shoe.
NOTES:
Connection of drains will add significant life to shaft seals. This is highly recommended.
See cut away view on page MP-4, page OA-2 for optional porting, pages 0A-5 and 0A-6 for optional manifolds and shaft couplings.
