Rod & Guided Rod
The rod type electric actuator has a familiar rod cylinder form suitable for push, pull, lift and press applications. The guide rod type includes rods to counter rotational forces instead of the drive and motor, and also resist shock and sustained lateral loads.
LEY Rod Type Electric Actuator
The LEY rod-type actuators mimic the form of pneumatic cylinders while providing the precise control of electric motion. They are suitable for a wide variety of applications including pushing, pulling, lifting, and pressing, with stroke ranges up to 500mm and horizontal work loads up to 100 kg. High-performance variants like the LE2Y and LEY*F feature improved speeds and acceleration, often incorporating battery-less absolute encoders that allow the system to maintain positional awareness even after power loss.
IP65 IP67 Protection Class
The LEY series actuators are modified for harsh environments through improved ingress protection. The X5 (IP65) and X7/X8 (IP67) options provide dust-proof and water-jet-proof capabilities by utilizing sealed aluminum motor covers, water-tight cable connectors, and specialized rod scrapers with lubrication retainers. These models also feature body vent holes to balance internal pressure, preventing contaminants from being drawn into the mechanism, which ensures reliable operation in wash-down or high-dust industrial settings.
LEY/LE2Y Guided Rod
The LEYG and LE2Y electric actuators integrate a rod-type drive with a bolt-on bearing block and double guide rods. These guide rods are designed to absorb rotational forces and resist heavy lateral loads, protecting the motor and drive mechanism from damage. Available with either slide or ball bushing bearings, these actuators offer high rigidity and precision, making them ideal for tasks that involve offset loads, such as lifting or pushing large objects on conveyors.
LEPY Miniature Rod
LEPY miniature rod-type electric actuators feature an ultra-compact form factor small enough to fit in the palm of a hand, making it ideal for precision applications in tight spaces. Available in two body sizes (6 and 10), it utilizes a 24VDC step motor to deliver a maximum work load of 2 kg or a pushing force of up to 50N, with stroke options ranging from 25mm to 75mm. The series offers high flexibility with four selectable motor cable entry directions and multiple mounting configurations, including side, bottom, and axial tapped options.
Piston Rod Ball Joint
The Piston Rod Ball Joint features a specialized line of spherical rod ends designed to simplify the design and assembly of oscillating mechanisms. These joints are available in a wide range of metric thread sizes, from M4 to M42, and offer an allowable inclination angle of up to 19 degrees. By providing smooth rotation and automatic centering, these ball joints effectively compensate for misalignment between the cylinder and the load, reducing friction and wear on the actuator.
Rod & Guided Rod FAQs
What are the primary applications for the LEY series?
The LEY series rod-type actuators are designed for push, pull, lift, and press applications. Common examples include use as lifters, stoppers, delivery systems, and press-fitting components.
What is the positioning repeatability of the LEY series?
The standard positioning repeatability is ±0.02 mm. A high-precision option is also available for certain models, offering repeatability of ±0.01 mm.
Can the LEY series handle high-speed transfers?
Yes. Depending on the motor and lead screw selection, maximum speeds can reach 1000 mm/s. It also supports high acceleration and deceleration of up to 5,000 mm/s².
Is pushing control possible with these actuators?
Yes. Users can select between positioning control and pushing control. Pushing control allows the actuator to hold a workpiece with a specific force, similar to a pneumatic cylinder.
What types of motors can be used with the LEY series?
We offers three main motor types:
- Step Motor (24 VDC): Ideal for high-load transfers at lower speeds.
- Servo Motor (24 VDC): Offers stable high-speed operation and quiet performance.
- AC Servo Motor (100W/200W/400W): Provides the highest output, speed, and acceleration.
Is there a manual override for the actuator?
Yes, the actuators feature a manual override adjustment screw, allowing for manual operation and adjustment when the power is off.
Can I use auto switches with the LEY series?
Yes, the body includes grooves for mounting auto switches to detect limit or intermediate positions. Water-resistant 2-color indication solid-state auto switches are also compatible.
