Linear Drives Training System

Model: 221-000

DAC Worldwide’s Linear Drives Training System (221-000) is a benchtop device which facilitates training in the design, function, installation, and alignment of common linear drive components. Fabricated from steel and aluminum, the training aid combines a variety of common industrial components and installation scenarios in one assembly.

This Linear Drives Training System includes two (2) ½” ground steel shafts, two (2) closed-type linear bearing blocks, one open-type linear bearing block, an aluminum sliding carriage, a 3/8” ball screw, and much more. Learners will use these components to study topics such as mechanical principles, rotary-to-linear motion drive, lubrication, and troubleshooting. This system utilizes industry-grade components, providing durability to stand up to frequent use, and to aide learners in becoming better prepared for the tasks they will encounter on the job.

Practice Hands-On Mechanical Skills for Various Applications

The Linear Drives Training System features a steel baseplate with two aluminum t-slotted mounting rails for component mounting. It also includes provisions for adjusting bearings pre-load, shimming and shaft paralleling activities, and installation of shaft seals (wipers). Learners will use these components to practice hands-on skills, such as discovering rotary input motion, mounting a robot or tooling turret, and troubleshooting position sensors.

In addition, the training system possesses elements that can be shimmed to establish level and parallel shaft conditions, allowing for various applications for converting rotary to linear motion to be demonstrated.

Expand Training with Additional Mechanical Options

The Brake Clutch Training System is only one of DAC Worldwide’s expansive mechanical training products, which also includes a Coupling/Shaft Alignment Trainer (208), a Brake Clutch Training System (220), a Chain Drive Trainer (223), and many more!

Optional Student Training Manual and CD-ROM Available

A copy of this course’s Student Training Manual and CD-ROM are available as optional learning aids with the training system. Sourced from the Exercises and Learning Activities, the Student Training Manual takes the technical content contained in the learning objectives, and combines it into one perfectly-bound book. The CD-ROM covers 14 power transmission topics, including linear motion (PTDA). If you would like to inquire about purchasing additional Student Training Manual or CD-ROM for your program, please contact your local DAC Worldwide Representative for more information.
