Product overview Precision ball screw assemblies in two material options: Steelbearing with aluminumalloy body: engineered for very low starting torque and speed microfeed applications. Stainlesssteel construction: optimized for positioning accuracy and consistent repeatability. Key benefits — why this product matters Low starting torque reduces the drive force required, allowing smaller motors, smoother starts, and lower power consumption for micromotion tasks. speed microfeed capability supports fast, fineresolution linear motion without sacrificing stability or control. Stainlesssteel option provides stable, repeatable positioning and longterm dimensional stability in demanding environments. How it solves common problems Minimizes stiction and backlash at startup so parts move precisely from the first step; ideal where tiny position changes matter. Supports cycle rates at fine increments, addressing bottlenecks in rapid precision feeding or scanning processes. Offers materials choices to balance weight and corrosion resistance: aluminumalloy for reduced mass and stiffness, stainless steel for durability and repeatable accuracy. Key attributes Function: converts rotary motion into precise linear motion for actuators, stages, and positioning systems. Materials: Steel bearing + aluminum alloy body — low mass, low starting torque, suitable for speed microfeed. Stainless steel — positioning accuracy, good repeatability, enhanced durability. Performance: minimum starting torque, capable of speed microfeed, accurate and repeatable positioning (stainlesssteel variant). Compatibility: integrates with standard stepper and servo drives, linear stages, motion controllers, and compact actuator assemblies. Typical applications (practical examples) CNC micromachining and engraving: enables rapid, precise microfeed when finishing delicate features or thin materials. Optical and metrology equipment: delivers fine, repeatable positioning for lens mounts, interferometers, and calibration stages. Medical and laboratory automation: reliable, lowtorque linear motion for dosing heads, pipetting stages, and samplehandling robots. What to expect in use Reduced motor size and power requirements for micropositioning systems with the aluminumalloy variant. Consistent, repeatable placement over many cycles with the stainlesssteel variant, suitable for production and inspection equipment. Straightforward integration into existing motion systems using common mounting and drive interfaces. Choose the material that matches your priorities: minimal starting torque and lighter weight (steel bearing + aluminum alloy) or maximum positioning accuracy and repeatability (stainless steel).
