No Embrittlement on Guide Rollers for Whistler Peak 2 Peak Cable Cars

Posted by Simon Barrell on Mar 31, 2010 1:56:00 PM

When you are hanging a record 1,430 feet above the ground in a heavy cable car you want to be sure that the rollers it is running on don’t suffer from embrittlement at low temperatures (-40°C). The Peak 2 Peak Gondola recently opened in Winter Olympics venue Whistler, British Columbia holds world records for the longest free span between ropeway towers (1.88 miles) and the highest point above the ground—436 meters (those same 1,430 feet).

Intech Power-Core Roller Mounting for Cable Car


Each of the 28 gondola cabins suspended on the 2.73 mile long cable is carried by a sophisticated roller mounting that has high resistance to abrasion under extreme conditions, as well as sound ultraviolet resistance. Those rollers are made with Intech Power-Core™ material and a rolled aluminum core, and they have a life-span in excess of 10 years to satisfy stringent safety requirements.

If you are lucky enough to spend some time in beautiful Whistler, and travel on the Peak 2 Peak gondola, do so confident in the high fatigue limit of the rollers that are carrying you across the valley. Intech Power-Core™ material is the only existing high-performance plastic which fulfills the broad spectrum of requirements set down by the cable car manufacturer to ensure your safety.

Self-Lubricating cam followers replace steel in outdoor applications

Our customers have been asking us to help them with components for machines that will operate in ever harsher conditions. Intech iCam Followers® and Power-Core™ guide rollers feature a unique crystalline structure that is resistant to flow under static load, and provides long-wearing, non-lubricated performance. The devices do not wear out the rail, do not absorb moisture and, when fitted with stainless steel bearings, are suitable for wash downs and harsh and corrosive environments.

Unlike other plastic material, Power-Core™ does not become brittle in low temperatures. iCam Followers® and Power-Core guide rollers reduce maintenance and down time by retaining good bearing fit from -40° to 160° F, retaining elasticity, and absorbing shock and vibration in sub-zero temperatures. The devices are not only quiet and easy rolling, they do not generate metal particles, which can further increase down time potential.

Intech Power-Core rollers, cam followers, and trolleys are assembled from precision machined high performance, self lubricating engineered plastic tires and quality roller bearings. The plastic part of the roller fully envelopes and embraces the bearing outer racer which in turn provides high capacity to carry side loads.

The Power-Core rollers and iCam Followers® are available in stock sizes with load capacity from 60 to 500 lbs. Trolley assemblies feature aluminum track and trolley systems with attachments. Custom sizes and dimensions and tire shapes can be developed to meet specific applications.
