Precision Motorized Lift Stage ELPB50C
High-quality ball-screw transmission for high repeat positioning accuracy and long service life.; Precision-ground worm gear drive with high load capacity and fine adjustment, with stepless lifting and low backlash.; Linear-bearing guides for high precision and smooth motion.; Servo motor and worm connected by a high-quality flexible coupling for synchronous transmission, good anti-deviation performance, low noise.; Fitted with zero and limit switches and an initial-zero function for accurate positioning and product protection.; Standard connection holes on both the base and tabletop for easy fixing and strong versatility.
Product Introduction
The ELPB50C precision motorized lift stage was developed specifically to solve the eccentric-load problem of vertical stage use. Its tabletop is horizontal with the drive force at the tabletop center and four over-constrained surrounding guides for good stability. The drive mechanism uses a ground screw with a screw nut and a standard servo motor for high resolution and positioning accuracy. The lift stage uses an orthogonal direction-changing mechanism with multi-axis support lifting to ensure smooth motion, high load capacity and long life.
