[![Browse Our Products](https://no-cache.hubspot.com/cta/default/62516/08b25f71-daf5-4226-916d-2693bd171a1d.png)](https://cta-redirect.hubspot.com/cta/redirect/62516/08b25f71-daf5-4226-916d-2693bd171a1d) ** ## From sliding door rollers to gears, motion components play a critical role in many transportation applications including: ● Public transit — trains, people movers, and light rail systems ● Electro-mobility (e-mobility) powertrain systems ● Ambulances, firetrucks, and other emergency vehicles ● Passenger van, cargo van, and refrigeration truck doors ● Aircraft tray tables, seat mechanisms, and accordion doors The components in these applications must minimize noise and vibration as much as possible to maximize passenger comfort. And whether they’re used on a firetruck or subway car, they must perform reliably despite the presence of harsh environmental factors and temperature fluctuations. With their long life and maintenance-free operation, our Power-Core™ polymer guide rollers, cam followers, gears and other components are up to the challenge. NVH - A Quiet, Smooth Ride Durability and Reliability in Harsh Conditions High Force in a Compact Form Factor NVH - A Quiet, Smooth Ride ![](https://www.intechpower.com/hubfs/Imported_Blog_Media/post05-1-1.jpg) ### Power-Core™ guide rollers are lightweight and dampen vibration more effectively than metals. The polymer also exhibits lower rolling resistance than metals, unlocking several benefits: - iNTECH sliding door rollers are smooth and quiet. When it comes to plastics concentricity and low runout are key to smooth quiet motion. 50% Quieter than metal (10Db).and 10-20% quieter than most plastics.  - Shocks Destroy Rollers. Transportation inherently involves harsh roads our material’s inherent damping characteristics counteract the shocks without damaging the components.  - Run-on Aluminum. Whereas metal rollers require costly hardened steel tracks, Power-Core™ guide rollers can roll on much less costly aluminum tracks for the life of the door. Durability and Reliability in Harsh Conditions ![](https://www.intechpower.com/hubfs/Imported_Blog_Media/post05-1-1.jpg) ### Our Power-Core™ guide rollers, gears and other motion components offer several advantages compared to metals and other plastics in transportation applications: - Power-Core components eliminate the metal-on-metal wear that can prematurely end the life of metal gears and sliding door rollers and tracks. And it needs no lubrication to keep rolling smoothly. - Most plastics permanently deform underload – PowerCore components keep their shape even under the heaviest loads, allowing them to roll smoothly for the life of the application.  - Don’t suffer plastics pitfalls, our motion components don’t swell if exposed to moisture. They also remain dimensionally stable across a wide operating temperature range and environments. High Force in a Compact Form Factor ![](https://www.intechpower.com/hubfs/Imported_Blog_Media/post05-1-1.jpg) ### Gears and other motion components must be able to meet the higher torque and speed requirements of motors in powertrain systems. Not only do our precision-machined polymer gears improve torque transmission efficiency, but their compact, lightweight design can meet space-limited powertrain system designs. - Our proprietary gearing technology enables our reinforced Power-Core™ polymer gears to withstand higher torque, operate with minimal noise, and improve operating speeds. - We can modify the gear teeth to meet these and other demands, including less thermal heat generation, an increase in wear life, higher load capacities, and more. - Small Design Changes, Big Savings. It's not uncommon for our modified teeth to be able to accomplish with a one-stage polymer gearbox what would commonly require a two-stage metallic gearbox. ## Get Started Bring your team, tools, and data together to launch high-impact inbound marketing campaigns in less time.
