A roller plunger incorporates a roller or bearing within its actuating part, enabling precise contact with objects such as workpieces for positioning or fixing purposes. It features a built-in spring that allows the actuator tip to retract under load and return to its original position once the load is removed. Roller plungers, along with ball and pin plungers, are key components in mechanical and industrial settings.
Roller plungers are widely used in machine tools and factory production equipment for positioning and securing workpieces. Their design allows for smooth rotation and minimal friction during contact, making them ideal for various applications, including limit switch actuators.
Adjustable driver and passenger seats and seat belt reel mechanisms benefit from the precise movement allowed by roller plungers.
They facilitate conveyor belt positioning and are used in semiconductor manufacturing for reliable equipment operation.
Roller plungers enable smooth adjustments in water-draining sinks and expandable tables, enhancing functionality and work efficiency.
The roller plunger consists of a roller (bearing), a body (main body), a pin, and a spring, operating either by sliding or rotary (lever) action. The spring force dictates the restraining force on the object, with variations designed for light or heavy loads.
Roller plungers vary by body shape, load capacity, and roller orientation, each suited for specific applications and mounting requirements.
Bolt type and mount type bodies cater to different installation methods, offering versatility in application.
Selection between light load and heavy load types depends on the operational requirements and the force needed for securing objects.
Roller orientation options include vertical and landscape orientations for mount types, influencing the direction of action and installation flexibility.
Roller plunger limit switches are critical for detecting mechanical movements or the presence of objects, often featuring a sealed design for dust-proof protection.
