The linear arm design provides controlled movement along a fixed path, helping maintain consistent tool positioning and perpendicular alignment during repetitive fastening tasks. Quick Answer LTS-Series torque arms support assembly tools and absorb torque reaction, using a linear arm design to provide controlled movement, improved ergonomics, and consistent positioning. --- ### Who This Is For - Manufacturing engineers - Process engineers - Quality engineers - Assembly operators - Ergonomics and safety teams - Automotive, aerospace, electronics, and general manufacturing facilities --- ### When Should You Use This? **Use LTS-Series torque arms when:** - Torque reaction from power tools needs to be managed - Applications require consistent, straight-line tool movement - Maintaining perpendicular alignment to the fastener is critical - Operator ergonomics is a concern - Workstations involve repetitive fastening in a fixed plane --- ### When Should You NOT Use This? **Do not use LTS-Series if:** - Tool support is not required - Multi-directional positioning is required → use ATS-Series - Extended reach is the priority → use CTA-Series - Vertical tool balancing is the primary requirement --- ### How LTS-Series Torque Arms Work **LTS-Series torque arms support assembly tools through a linear motion system:** - Tool is mounted to the arm - Arm absorbs torque reaction generated during fastening - Linear sliding mechanism allows movement along a fixed path - Arm helps maintain perpendicular alignment to the fastener - Operator guides the tool with supported movement **Result:** Improved ergonomics, reduced operator fatigue, and more consistent fastening alignment --- ### Core Features - Linear arm design for controlled, straight-line movement - Absorbs torque reaction from electric and pneumatic assembly tools - Maintains perpendicular tool alignment throughout the fastening cycle - Helps reduce side loading and cross-threading - Compact design for production workstations - Smooth vertical movement for improved operator ergonomics - Includes integrated tool balancer(s), depending on model --- ### Configuration Options - Linear travel based on model selection - Bench, wall, and rail mounting options - Compatible with a variety of tool holders and clamps - Tool clamp can be configured for in-line, pistol grip, and right-angle power tools ### Available Models (LTS-Series Linear Torque Arms) The LTS-Series is available in multiple torque capacities and travel ranges to support ergonomic fastening applications requiring precise linear movement. Each model is designed to absorb torque reaction while maintaining perpendicular tool alignment and improving operator comfort. **LTS-Series Model Chart** | Model | Item Number | Max Torque | Clamp Diameter | Height | Arm Reach (Min–Max) | Max Tool Weight | | --- | --- | --- | --- | --- | --- | --- | | LTS-15 | 260604 | 11 lbf.ft (15 N·m) | 1"–1¾" | 30.6" | 12.7"–19.7" | 2.9 lbs | | LTS-25 | 260605 | 18.4 lbf.ft (25 N·m) | 1"–2¼" | 39.1" | 17.8"–30.6" | 5.5 lbs | | LTS-40 | 260606 | 29.5 lbf.ft (40 N·m) | 1"–2¼" | 39.1" | 20.8"–32.9" | 7.7 lbs | | LTS-80 | 260607 | 59 lbf.ft (80 N·m) | 1"–2¼" | 43.8" | 19.5"–31.5" | 12 lbs |   --- Model Selection Guide | If you need... | Recommended Model | | --- | --- | | Low-torque precision assembly | LTS-15 | | Light-duty assembly tools | LTS-25 | | Medium-duty production tools | LTS-40 | | High-torque assembly tools | LTS-80 | | Compact workstations | LTS-15 or LTS-25 | | Longer vertical travel | LTS-40 or LTS-80 | --- ### Compatibility Notes - Compatible with electric and pneumatic assembly tools. - Tool clamp orientation can be configured for in-line, pistol grip, and right-angle tools. - Mountable to workbenches, walls, or rail systems using the appropriate mounting hardware. - Each LTS model includes the appropriate tool balancer(s) for its intended application. LTS-15, LTS-25, and LTS-80 include two balancers, while the LTS-40 includes one medium-sized balancer optimized for 40 N·m applications. --- ### Construction - Steel column with a polished chrome finish. - Tool balancers feature aluminum housings, braided cables, adjustable spring tension, and integrated locking mechanisms. - LTS-15 features an industrial-grade thermoplastic support slider with integrated steel bearings for lower-torque applications. - LTS-15 linear arm is manufactured from 7000-series aluminum with polished chrome steel sliding rods and thermoplastic-housed steel bearings. - LTS-25, LTS-40, and LTS-80 feature aluminum support sliders with steel bearings for smooth, long-lasting vertical movement. - LTS-25, LTS-40, and LTS-80 linear arms are manufactured from 7000-series aluminum with polished chrome steel sliding rods and steel bearings. --- ### Setup & Adjustment 1. Securely mount the LTS-Series torque arm to a compatible bench, wall, or rail mounting system. 2. Install the appropriate tool holder or clamp for the assembly tool. 3. Configure the tool clamp orientation for in-line, pistol grip, or right-angle tools as needed. 4. Adjust the arm within its available linear travel range to suit the workstation. 5. Verify smooth vertical movement and proper tool alignment. 6. Check that all mounting hardware, clamps, sliders, and balancers are securely fastened before beginning production. --- ### Common Applications The LTS-Series is commonly used in: - Electronics assembly - Medical device manufacturing - Aerospace assembly - Automotive manufacturing - General industrial assembly - Production workstations requiring straight-line fastening - Compact assembly cells --- ### Use Cases (Real-World Examples) #### Assembly Line Fastening **Problem:** Inconsistent tool angle causes fastening issues and quality defects. **Solution:** The linear arm maintains perpendicular alignment throughout the fastening cycle for improved consistency. #### Electronics Manufacturing **Problem:** Side loading increases the risk of cross-threading and fastener damage. **Solution:** The LTS-Series keeps the tool aligned with the fastener while absorbing torque reaction. #### Production Workstations **Problem:** Operators experience fatigue from supporting tool weight and torque reaction during repetitive fastening. **Solution:** The linear arm supports the tool while reducing operator strain and improving ergonomics. #### Compact Assembly Cells **Problem:** Limited workspace requires controlled tool movement without sacrificing ergonomics. **Solution:** The compact linear design provides smooth, precise movement while maximizing available workspace. --- Maintenance  - No calibration is required. - Periodically inspect the arm, sliders, balancers, and mounting hardware for wear or damage. - Verify that all fasteners, clamps, and moving components remain secure before use. - Adjust tool balancer tension as needed to accommodate changes in tool weight. --- Integration & Advanced Notes - Compatible with electric and pneumatic assembly tools. - Integrates with compatible tool holders, clamps, and balancers. - Designed for manual production workstations requiring precise linear movement. - Mechanical system requiring no electrical power or electronic controls. - Helps improve ergonomic performance while maintaining consistent fastening alignment. --- ### Media & Supporting Content                                                         ![](https://mountztorque.com/hs-fs/hubfs/image-png-1.png?width=670&height=430&name=image-png-1.png) ![](https://mountztorque.com/hs-fs/hubfs/image-png-2.png?width=670&height=446&name=image-png-2.png) -
