CJ Bearings are Made in the USA - Consistent Quality and Fast Delivery

One of the biggest questions consumers of composite wound bearings ask is “What is the country of origin?”  Many suppliers have stopped making these bearings in America and have now offshored their production or simply purchase them from manufacturers overseas – generally in China. This usually results in a much lower quality bearing with long lead times.

Plastic Bearings Cool Bottled Beverages and Facilitate Frosty Transport

January 20, 2015

CJ Bearings Cool Bottled Beverages and Facilitate Frosty TransportYou may have read our recent Shooting Star about versatile plastic bearings in a range of winter activities. Plastic bearings excel as a replacement for bronze in cold-climate applications, thanks to their ability to resist moisture form snow and sleet, plus resist freezing temperatures. But plastic bearings also excel in cold-beverage transport, too. Here’s how we helped a major manufacturer of refrigerated truck compressors replace failing bronze bearings with reliable plastic.

Composite Bearings Increase Riders’ Mobility on Mass Transit

January 6, 2015

Composite Bearings Increase Riders’ Mobility on Mass TransitWe recently completed a particularly gratifying application, as we retrofitted wheelchair lifts that are located on commuter buses. 

Challenge:

Our client manufacturers transit wheelchair lifts, which enable commuters of all abilities to access public transportation. The lifts are attached to commuter busses, and enable wheelchair commuters to roll onto a flat ramp at street level and be lifted to bus level, before the ramps fold back into position. Our client noted their bronze bearings were causing vibration that hindered the lifts from a smooth deployment. They needed to replace the poorly-designed bronze bearings to ensure a safe ride from sidewalk to bus.

Lifetime Improvements with Filament Wound Composite Bearings

Lifetime Improvements with Filament Wound Composite Bearings

The life expectancy of filament wound composites like TriStar's CJ product can be improved by understanding some of the typical failures. One consideration is the shaft material. In some applications where the motion is oscillating and at variable frequencies, the bearing can experience rapid wear. This is caused by small angle oscillation or small amplitude vibration and the resultant fretting corrosion. The wear debris that occurs can quickly become an abrasive that dramatically shortens life.

CJ Bearings Provide Smooth Sailing to Marine Navigation

September 25, 2014

CJ Bearings Provide Smooth Sailing to Marine NavigationAn interesting application for marine navigational equipment came through our lab recently when we partnered with the manufacturer of a self-steering rudder. This auxiliary helm application was the perfect match for CJ bearings, which are among the best for chemical and salt-water tolerance.
