It features lubrication-free elastic seals and standard non-locking manual override, supporting single piping or dense manifold stacking for valve islands with Rc1/4 & Rc3/8 ports. Widely used in robotic arms, vacuum adsorption, air blowing, packaging, textile and woodworking automation equipment.

SOLH HRQ dual piston rack & pinion rotary cylinder includes micro sizes HRQ2/3/7 and medium-to-large HRQ10~HRQ200 with infinitely adjustable swing angle 0~190°. It outputs higher torque and stronger bending/radial load capacity than vane rotary actuators. Three configurations are available: basic mechanical stop buffer (low-cost for light low-speed duty), -A integrated hydraulic shock absorber (high-speed heavy load precise stopping), and -A(S) hydraulic version with stainless steel end caps for humid & slightly corrosive environments. The rotary table features central hollow through hole for tubing and wiring, and side sensor slots compatible with universal magnetic reed switches. Micro models adopt bottom mounting holes while medium/large sizes provide multi-side mounting taps for flexible layout. Pre-filled long-life grease enables lubrication-free operation. Selection requires simultaneous verification of torque, radial/axial load and bending moment. Widely used for rotary indexing in automatic assembly, material sorting, packaging capping and jig turnover stations.

Switchgear Door Lock Bent Plate – Product Details and Applications The Switchgear Door Lock Bent Plate is a critical mechanical component designed to enhance the safety and operational integrity of electrical switchgear systems. It serves as a key element in the door locking mechanism, ensuring the secure closure of switchgear cabinet doors. Typically made from robust materials such as stainless steel or zinc-coated metal, the bent plate offers durability, resistance to corrosion, and strength under mechanical stress, ideal for both indoor and outdoor switchgear installations. The bent plate features precise bends and dimensions to fit perfectly within the locking assembly, working seamlessly with handles, latches, or electromagnetic locks. It plays a crucial role in achieving smooth mechanical alignment between the door and frame, preventing accidental door openings caused by external vibrations or impact. Some variants are designed to support additional locking mechanisms, such as padlocks, to offer enhanced access control and security during maintenance or operation.

Guide rail for electrical switchgear is a mechanical structure for supporting, guiding and mounting switchgear components, mainly used in electrical equipment. The core goal of its design is to ensure the stability of the switchgear, accurate alignment and ease of subsequent maintenance and replacement. Rails are usually made of aluminum alloy or galvanized steel, with strong load carrying capacity and corrosion resistance. For special environments (such as wet or corrosive places), the rails will be made of anti-corrosion treatment or stainless steel. Common rail shapes include "C", "U" or "L" sections, designed to be compatible with many types of switchgear. In addition, the standard size of the guide rail conforms to international specifications, which facilitates the modular installation of the equipment. In order to cope with the harsh environment, the surface of the guide rail may be galvanized, electrophoretic coating and other treatments to improve corrosion resistance.
