Lim-Tec Acme Screw Linear Actuator LAP Series

Product catalog summary
Overview: This document outlines the specifications and guidelines for LAP Series Linear Actuators, focusing on duty cycle calculations, model selection, and performance parameters.
Specifications: The LAP Series includes Acme and Ball screw actuators. Acme screw actuators are ideal for low load rates, while Ball screw actuators are better for higher loads due to their durability and lower overheating risk.
Duty Cycle Calculation: Duty cycle (Fu%) is defined as the working percentage within a 10-minute period. Specific limits are set for different series: LAM series at 10%, LAP22,25 at 25%, and LAP28,32,35,40,56,63,80 at 30%. Ball screw actuators can handle a 100% duty cycle.
Model Selection: Model selection involves evaluating duty cycle, load speed, stroke requirements, and stability. If stability is inadequate, a larger actuator should be selected. Consultation with engineers is recommended for specific load and stroke conditions.
Performance Tables: Performance metrics for LAP and LBP series actuators are detailed in tables, covering speed, dynamic load, motor power, self-locking coefficients, and weight, with distinctions between DC and AC motor-driven actuators.
Self-Locking Mechanism: Actuators are classified by self-locking capabilities: static, dynamic, uncertain, and non-self-locking, with specific coefficients for each type.
Installation and Customization: Installation guidelines consider stroke length and stability. Custom designs and temperature requirements should be discussed with engineers.
Graphical Data: Graphs on stability and critical buckling force help evaluate actuator performance under various load and stroke conditions.
Additional Notes: Consultation with Lim-Tec engineers is advised for special requirements. The operational temperature range for actuators is -15℃ to +40℃.
