🛠️ Product Overview: BEd-301/6
asynchronous motor-driven hydraulic actuatorexplosion-proof housing. It is widely used as the driving force for industrial brakes and various linear actuation mechanisms.
Explosion-Protected Electro-Hydraulic Thruster (B=Explosion-proof, E=Electro-hydraulic, d=Flameproof).

Explosion-Proof Design (Ex d I Mb):
and other hazardous areas. It prevents internal sparks from igniting the surrounding explosive atmosphere (specifically rated for Methane and Coal Dust environments).
Combines the motor, oil pump (impeller), and cylinder in one casting. This makes it leak-proof, compact, and highly reliable compared to separate hydraulic power units.
Fail-Safe Capability:
fail-safe brake systems. If power fails, the thruster retracts (via spring or gravity), and the brake automatically engages to secure the load.
Non-oil-immersed motor: The motor is sealed off from the hydraulic oil, preventing insulation degradation.
The piston rod is plated to resist wear and corrosion.
The hydraulic system is fully sealed with double-sealed oil chambers, reducing the need for frequent maintenance and extending service life.
The BEd-301/6 is essential for safety in hazardous locations:
Operating brakes and valves in underground shafts and conveyor systems.
Actuating machinery in areas with explosive vapors.
on cranes, hoists, and large conveyors.
Safety systems for ship unloaders and gantry cranes.
Check the hydraulic oil level regularly. Use DB-25 hydraulic oil for standard temperatures. Use YH-10-20℃.
< -20°C), consider ordering the model with a built-in to prevent oil viscosity issues.
The piston rod should not bear radial loads (side forces); it is designed for axial (push/pull) forces only.
