Belt Drive
An LEFB slider, or rodless, type electric actuator features a load mounting platform situated above a belt drive. A flexible seal band permits platform movement while preventing grease and foreign matter from entering the drive. Advantages include shorter overall length than rod types, plus longer strokes and higher speeds than ball screw drives.
LEFB Electric Actuator, Slider Type, Belt Drive
An LEFB slider, or rodless, type electric actuator features a load mounting platform situated above a belt drive. A flexible seal band permits platform movement while preventing grease and foreign matter from entering the drive. Advantages include shorter overall length than rod types, plus longer strokes and higher speeds than ball screw drives.- Body sizes: 16, 25, 32
- Maximum speed: 2000 mm/s
- Maximum stroke: 2000 mm
- Positioning repeatability: ±0.1 mm
- Motor types: high load step motor or high speed servo motor

LEFB Belt Drive Slider, Battery-less Absolute Encoder
The rodless LEFB slider is an electric actuator with a load mounting platform situated above a belt drive. A flexible seal band permits platform travel while preventing foreign matter from entering the drive. Slider advantages include a low profile height, shorter length than a rod with equivalent stroke, plus longer strokes and higher speeds than a ball screw driven slider. This version includes a 24VDC motor with a battery-less absolute encoder. This encoder allows the actuator to be powered down without losing its positional awareness. The machine's PLC can access the controller's operational and positional step data through several fieldbus protocols, IO-Link, or parallel I/O.
- Body sizes: 16, 25, 32
- Maximum work load (horizontal only): 19 kg
- Maximum speed: 1500 mm/s
- Stroke range: 300 to 2000mm in 100mm increments
- Positioning repeatability: ±0.08mm

LE2FB, High Performance Slider, Belt Drive, for Manifold Controller
LE2FB is a belt driven slider with a high performance motor and batteryless absolute encoder that is compatible with the JXD1-M manifold controller. LE2FB differs from LEFB by having a different cable connector and no compatibility with JXC controllers. The belt drive allows higher speeds and longer strokes compared to the LE2FS ballscrew type. This slider also consumes less power than earlier LEFB versions. The JXD1-M manifold controller can detect the actuator type, size and stroke when connected. The manifold can operate up to 16 axes. The controller and cables are ordered separately, simplifying the part number.
- Body sizes: 16, 25, 32
- Stroke range: 300 to 2600mm
- Maximum work load: 19 kg (size 32)
- Maximum speed: 1700mm/s (size 32)
- Maximum acceleration: 3,000 mm/s²
- Positioning repeatability: ±0.08mm
- Motor type: 24 VDC step motor with battery-less absolute encoder
