Product Description

The KR-SZDSM20x140 linear guide is a high-precision motion system incorporating the SZDSM20x140 linear bearing, engineered for industrial automation, CNC equipment, and robotic applications. This KR linear bearing 20x140 supports bidirectional motion with a 20mm shaft diameter and 140mm stroke length, rated for 10A continuous current. It operates within 12-48V DC and -30°C to 100°C environments, featuring IP65 protection. The unit integrates 4 digital inputs and 2 analog outputs, compatible with RS-485/CAN interfaces for daisy-chaining up to 8 modules. Its modular design enables zero-backlash performance under 15kN axial loads, complemented by a built-in 5mm proximity sensor range for positional feedback. A 2.4" OLED displays real-time diagnostics. While offering exceptional rigidity and ±5μm repeatability, its installation requires precise alignment. The compact housing (140x60x40mm) suits space-constrained setups. An optional 2000mAh backup battery preserves settings during power interruptions. Ideal for semiconductor manufacturing and packaging lines, this bearing system excels in high-speed (2m/s) applications demanding minimal maintenance.
