MA Series ball screw jacks offer a significant upgrade over traditional acme screw jacks, ideal for high-speed linear motion, continuous duty cycles, and applications demanding high precision and efficiency. These ball screw jacks reduce energy consumption, have zero axial clearance, provide long-lasting performance, and allow precise estimation of the product’s lifetime. They are suitable for both push and pull loads and can be mounted in vertical (upward/downward) or horizontal orientations.

Features:

  • Continuous Duty Cycle: Capable of 100% duty cycle without overheating.
  • Energy Efficient: Up to 50% energy savings and reduction in installed power due to high efficiency.
  • Zero Axial Clearance: Ensures high precision and eliminates wear on the nut.
  • Low Backlash Gearbox: ZI involute profile gearbox, designed for reduced angular backlash.
  • Versatility: Suitable for varied industrial applications like steel mills, sheet metal production, plastic production, food and beverage, telecommunications, and more.
  • Multiple Mounting Options: Can handle both upward/downward vertical or horizontal applications.

Product Series:

MA BS Mod.A Series (Travelling Screw)

  • High Efficiency: Ball screw jacks with travelling screw for higher performance.
  • Gearbox Ratios: From 1:4 to 1:32 for efficient transmission.
  • Lubrication: Long-life synthetic oil-lubricated worm gear.
  • Speed: Input speed of up to 3000 rpm.
  • Ball Screw Sizes: Available in 8 sizes with ball screws ranging from Ø16 mm to Ø120 mm.
  • Load Capacity: Supports loads from 5 kN to 350 kN.

MA BS Mod.B Series (Travelling Nut)

  • Similar Performance: Same benefits as Mod.A but with a travelling nut design instead of a travelling screw.

Accessories:

  • Stroke Length Limit Devices: Available with magnetic or inductive proximity sensors.
  • Position Control: Incremental or absolute encoders for precise positioning.
  • Motor Compatibility: IEC standard motors (AC/DC) and brushless servomotors supported with special flange adapters.
  • Protection & Safety: Bronze guides, stop nut devices, protective bellows, and anti-turn devices for added safety.
  • Special Materials & Lubricants: Stainless steel (AISI 303, 304, 316) options available. Lubricants tailored for high/low temperatures and food industry use.

These screw jacks are perfect for industries seeking enhanced productivity, efficiency, and cost savings while ensuring high performance and reliability.
