4 Applications Where Polymer Materials Excel in Aircraft Bearings

February 14, 2017

Polymer Materials Excel in Aircraft Bearings

Aircraft bearings have strict requirements for quality and performance; they must tolerate massive fluctuations in temperatures, pressurized cabins, tough weather conditions, plus extreme cargo loads. But there are 4 top polymers that are becoming the go-to materials in the aerospace industry. Let’s explore the advantages of Ultracomp, CJ, TriSteel and Rulon in various aircraft bearing applications.

Plasma Treatment Helps Aircraft Bearings Take Flight

February 24, 2015

Plasma Treatment Helps Aircraft Bearings Take FlightNo two applications are ever the same at TriStar; particularly in our Surface Modification Lab. I wanted to share how we recently helped an aerospace client improve the rubber-to-metal bond of their engine wire clips via plasma treatment. By “super cleaning” the components with plasma treatment, we prevented the rubber from delaminating, and avoided potential disaster.

Aircraft Bearings: Polymer pivots, steers and lifts with better performance

July 9, 2014

Aircraft Bearings: Polymer pivots, steers and lifts with better performanceHistory was made last month in the aviation industry as Boeing delivered its 1,500th 747 aircraft – the first wide-body airplane to reach this delivery milestone.  As a longtime provider of bearings for aircraft ranging from helicopters to military jets and even space components, TriStar shared in the marvel of the moment.

Aircraft bearings have strict requirements for quality and performance; they must tolerate massive fluctuations in temperatures, pressurized cabins, all-weather conditions, plus extreme loads.   And polymer bearings are becoming the go-to material for lift, tilt and pivot points in the steering, fuselage, wings and other areas of commercial aircraft.   Unlike metal bearings, they provide self-lubricating service to save on greasing and maintenance costs.  Here’s a sampling:
