Switchgear Drawer Moving Parts Accessories are essential components designed to enhance the functionality and reliability of switchgear systems. These accessories include various parts such as guide rails, rollers, locking mechanisms, and support brackets, all engineered to facilitate smooth operation and safe handling of drawer units within electrical switchgear cabinets.

SOLH TR twin shaft cylinder is manufactured in accordance with JIS industrial standards. It adopts a single-piston dual guide shaft structure matched with extended slide bearing bushes, featuring high structural rigidity, excellent torsion resistance and strong anti-deflection capacity superior to cost-effective TN twin shaft cylinders. Bore sizes range fully from φ6 to 32 mm, including standard single-rod TR, double through rod TRW and lightweight compact TRJ variants. Anti-rotation accuracy reaches ±0.1° for bores ≥16 mm and ±0.2° for φ6/φ10 small bores; dual shafts restrict swinging deviation to guarantee stable operation over long strokes. An adjustable front rubber cushion pad cooperates with fixed rear buffer for stroke trimming, impact absorption and noise reduction. Three-way mounting (top, bottom, side) and optional dual-side porting are available; side grooves allow direct assembly of magnetic switches without extra brackets. Built-in magnetic rings marked suffix S are standard, while non-magnetic customized versions are offered for magnetic interference sensitive occasions. Operating pressure ranges 0.15~1.0 MPa with working temperature from −20℃ to 70℃. Standard Rc thread can be converted to G thread or NPT thread for overseas engineering projects. Distinguished from CXS twin cylinders: TR outputs single thrust with prominent mechanical rigidity and stable side-load resistance in long-stroke applications; CXS features dual pistons for double thrust, lower friction and smoother high-speed reciprocation suited for high-frequency short-stroke pick-and-place. Widely applied in precision positioning, workpiece pressing, long-distance stopping & transfer and general automation stations requiring reliable guiding under medium-light loads.

The Switchgear Side Cover Strip is a vital component designed to enhance the protection and aesthetic appeal of electrical switchgear assemblies. Made from high-quality, durable materials, this strip serves as a protective barrier, shielding the internal components of the switchgear from dust, moisture, and other environmental contaminants. Its design ensures a secure fit along the edges of the switchgear, preventing accidental contact with live parts and contributing to overall safety.

SOLH 4A series 5/2-way and 5/3-way air-operated directional control valves are the full pneumatic counterpart of the classic 4V electromagnetic solenoid valve series. Driven entirely by external pneumatic control signals with no coils or electrical parts inside, this valve achieves inherent explosion-proof safety and serves as the core control unit for non-electric pneumatic loops, hazardous explosive areas and safety interlock systems. It adopts high-precision spool configuration and robust aluminum alloy housings, sharing identical installation dimensions and flow characteristics with the 4V series for seamless direct replacement and upgrade between electric-driven and full-pneumatic control schemes. The standard five-port layout follows industry universal specifications: P for main air supply inlet, A and B as working ports connected to two chambers of double-acting cylinders for extension and retraction regulation, R and S as exhaust ports compatible with standard silencers to reduce operational noise. The 5/2-way lineup supplies single pneumatic control and double pneumatic control options. Single air-controlled models switch upon receiving control air signals and automatically reset by built-in springs once the control pressure disappears to deliver fail-safe protection. Double air-controlled variants feature no return springs and lock the current spool position persistently after control air is disconnected, supporting long-duration positioning and pressure retention without sustained control air input. 5/3-way versions are exclusively double air-driven with three selectable neutral configurations: closed center (Type C) seals all ports to lock cylinders and prevent vertical falling; exhaust center (Type E) vents A/B ports to atmosphere for pressure release and manual commissioning; pressure center (Type P) feeds compressed air to both working ports for synchronous clamping and force balance adjustment. Suitable for filtered compressed air within 0.15~0.8 MPa working pressure, the whole series supports lubrication-free operation and works reliably from -20℃ to +70℃. Widely applied in chemical plants, painting workshops, mining and other explosion-risk environments, it cooperates with mechanical valves, hand-operated valves and air pilot valves to build complete all-pneumatic logic control systems for double-acting cylinders.
