Thermal Expansion a Key Consideration in Plane Bearing Design

April 17, 2018

Blog_20180417Thermal Expansion a Key Consideration in Plane Bearing Design

We are all aware that plastics expand and contract at different rates. When designing plastic plane bearings, one of the most critical considerations is to understand the thermal reactions of the material; designing not just for the normal operating temperatures of your environment, but to consider the minimum and maximum operating temperatures as well. Otherwise, you may lose the press fit (in cold temperatures) or expand to the point of shaft seizure (with hot temperatures).

Which Bearing Material for Gears Is Best?

This question was posed to me at a recent customer site visit. Ultimately, your choice of bearings for gear materials comes down to the friction, speed, and pressure of your application. And both bronze bearings and polymers can each play a role. Let’s dive in:

UHMW 101: From Molecular Weight to Machining

UHMW remains a hot topic here on Tech Talk, and on our Ask the Experts portal, too. Why is this true? For one, the material offers great value over other plastics, and has good abrasion-resistance properties, plus it is processed via a unique control (no molding, only machining). This trifecta of properties values make for a distinctive material, read on for more top FAQs:

Can Composites Replace Bronze Plain Bearings?

If you’re a regular reader of Tech Talk, it will be no surprise that we’re big fans of composite plastics as a replacement for bronze bearings.

Composites offer a simple, one-piece construction and they eliminate many of the downsides of metal bearings – which we will outline below. When designing for your next application, here’s why you might want to consider a composite design instead.

 Aerospace Plastic Seals and the Rulon Connection

Did you catch the live launch of Space X last week? This event marked a major milestone in spaceflight, while also unleashing the endless possibilities of future space exploration. For me, it brought to mind our long partnership of codesigning aerospace plastics such as seals and bearings with NASA engineers. Here’s how we helped the agency master a design to turn CO2 waste into potable drinking water aboard orbiting spacecraft.

 Surface Energy of Fluoropolymers: A Plasma Case Study

Today we’re heading to the lab to review the surface energy of fluoropolymers after plasma treatment. As you may know, a fluoropolymer is a polymer containing carbon, and one where nearly all of the hydrogen has been replaced with fluorine.

Which Bearing Types Overcome Dusty Environments?

Dust and debris are a challenge to all bearings. but impact some bearing types more than others. Food processing lines, paper mills, construction sites and other environments produce airborne contaminants than can clog and impede bearing rotation. And lubrication levels play a key role in bearing success or bearing failure, too. Let’s clear the dust to review bearing attributes for overcoming a dusty environment.
