UBA, UAL series

Product catalog summary
Overview of UBA and UAL Series Linear Actuators
The document provides comprehensive details on the UBA and UAL series linear actuators, focusing on manufacturing features, technical data, and performance with various motor types.

Manufacturing Features
The actuators are designed with a timing belt transmission and aluminum pulleys for low inertia. The housing is a monobloc design made from hardened aluminum alloy and steel, ensuring compactness and strength. Precision is achieved through specific materials and processes for acme and ball screws, minimizing pitch error and axial backlash.

Technical Data
  • UBA Series: Sizes range from 1 to 5, with varying push rod and outer tube diameters, supporting different dynamic and static loads.
  • UAL Series: Similar specifications to the UBA series but with acme screw options and different load capacities.

Performance with Motors
Performance data is provided for both series with AC 3-phase, AC 1-phase, and DC motors, detailing linear speed, dynamic load, motor power, and self-locking coefficients. Efficiency is calculated based on transmission, screw-nut, and bearing efficiencies.

Key Specifications
  • Push rod diameters: 25 mm to 50 mm.
  • Outer tube diameters: 36 mm to 70 mm.
  • Dynamic load capacities vary across sizes and motor types.
  • Ball screw and acme screw options offer application flexibility.

Conclusion
The UBA and UAL series are designed for high precision and load capacity, suitable for various industrial applications.

Specifications
The document details the efficiency calculations for UBA and UAL Series actuators, with specific formulas for dynamic efficiency. Performance data for UAL Series actuators with DC motors is also provided.

Dimensions and Technical Features
Standard stroke lengths and adjustments for longer strokes are detailed, along with dimensions for various actuator sizes.

Options and Accessories
Options include electric motor terminal box positions and actuator attachments. Accessories like magnetic stroke end switches are available to limit stroke length and prevent damage.

Notes
Different stroke lengths are available upon request, and specific handling is required for actuators with brake motors.

Specifications
The document outlines the construction and specifications of actuators, including the use of magnetic reed switches and inductive proximity switches for position sensing.

Procedures
Reed switches must be connected to a control circuit, and their position can be adjusted. Inductive proximity switches are fixed.

Electric Features
Reed switches operate at 3-130 V DC/AC, while inductive proximity switches operate at 10-30 V DC.

Accessories
Available accessories include anti-turn devices, safety nuts, protective bellows, and rotary encoders.

Special Designs
Customizations are available for specific applications, including stainless steel components and special lubricants.

Ordering Code
A detailed ordering code system is provided for specifying actuator series, size, stroke, attachments, switches, and accessories.

Safety and Installation Notes
Users are advised to verify alignment, ensure correct wiring and voltage, and check stroke end switches before use.
