BCS RODLESS SCREW DRIVE ACTUATORS

Product catalog summary
Overview of BCS Rodless Screw Drive Actuators
This document provides comprehensive details on BCS rodless screw drive actuators, suitable for light to moderate load applications. These actuators are customizable with stroke lengths up to 3 meters and offer various screw options to meet different performance requirements.
Key Features
  • Adjustable carrier bracket with solid bearing rods for enhanced load support.
  • Options for solid nuts (bronze or engineered resins) and ball nuts to cater to different performance needs.
  • Protection against contaminants and a high thrust bearing assembly design.
  • Customizable bearing tension and free play tailored to specific applications.
Specifications
  • Available in sizes BCS10, BCS15, and BCS20, each with distinct dimensions and specifications.
  • Multiple screw technologies including Acme and ball screws, with detailed critical speed capacities.
  • Specifications cover maximum thrust, stroke, and inertia values for both metric and US conventional systems.
Support and Mounting Recommendations
  • Surface mount and tube supports recommended for long stroke lengths.
  • Auxiliary carrier options to double load capacity and enhance bending moments.
  • Carrier bracket bolt adjustments for improved rigidity and reduced lateral play.
Performance and Durability
  • Endurance Technology features for enhanced durability and extended service life.
  • External bumpers and stainless steel sealing bands for added protection and longevity.
Ordering and Customization
  • Options for motor or gearbox installation by Tolomatic.
  • Various mounting and switch options available for customization.
Critical Speed and Load Capacities
  • Charts and tables provide detailed information on critical speed capacities for different screw and nut combinations.
  • Maximum thrust and life capacities are outlined for both Acme and ball screws.
Specifications for Switches and Actuators
The document details specifications for various switches and actuators, including Reed DC, Reed AC, and Hall-Effect DC switches. Key specifications include operating voltage, power rating, operating temperature, and switching logic. Details on cable shielding and quick disconnect couplers are also provided.
Procedures
Instructions for the installation and replacement of switches emphasize correct orientation and avoiding over-tightening. Specific guidelines are provided for replacing quick disconnect switches manufactured before July 1, 1997.
Standards and Recommendations
Warnings against exceeding power ratings to prevent sensor damage. Recommendations include using Tolomatic sizing and selection software for actuator selection, considering factors like load capacity, motion profile, and lead screw selection.
Performance and Life Expectancy
Graphs illustrate temperature vs. current and voltage derating for different switch types. Reed switch life expectancy is noted to be up to 200 million cycles, depending on conditions.
Installation Information
Detailed wiring diagrams are provided for different switch configurations, including Reed and Hall-Effect switches. The importance of correct wiring and orientation is emphasized.
Selection Guidelines
A step-by-step guide for selecting the appropriate actuator, considering factors such as load capacity, motion profile, and motor selection. The importance of calculating load factors and selecting the correct lead screw is discussed.
Ordering Information
Instructions for ordering include selecting model type, motor mounting, switch type, and additional options like tube supports and mounting plates. Part numbers for field retrofit kits and auxiliary carriers are provided.
Additional Notes
The document includes a caution about the solid bearing 2:1 rule and speed factor considerations for applications with high speed or significant shock and vibration.

DYNAMIC BENDING MOMENTS AND LOADS Please see BCS Carrier Bracket Bolt Adjustment on page BCS_6 Breakaway torque will increase when using the Auxiliary carrier option. When ordering, determine your working stroke and enter this value into the configuration string. Overall actuator length will automatically be calculated. *Loads shown in table are at minimum “D” dimension, for ratings with longer “D” dimension see graph below. Rates shown on charts were calculated with these assumptions: 1.) Coupling between carriers is rigid. 2.) Load is equally distributed between carriers.
