Self-lubricating Bearings for the Lumber Industry: durable and environmentally-friendly

July 7, 2014

4)	Self-lubricating Bearings for the Lumber Industry:  durable and environmentally-friendly  Self-lubricating bearings touch nearly every piece of equipment in the lumber industry; from the track road arms of timber harvesters (download PDF), to the kilns used to dry-finish boards used in housing construction and other applications.  Composite bearings offer durability and reliability, but more importantly for an industry dependent on fragile ecosystems, they protect the environment from the oil spillover that seeps into the ground when metal bearings are greased in the field.

Plane Bearings and Operating Limits: A composite comparison

July 1, 2014

Comparison of Operating Limits - Plane Bearing MaterialsI had a great conversation this week with an engineer seeking materials for a plane bearing application.  We spoke at length about the pros and cons of different materials including composites, bronze, acetals, and carbon alloy.  We also reviewed how PV is the most important factor in determining how well a material will perform as a plane bearing.   Pressure, velocity, heat and temperatures are also contributing factors.

Medical-grade plastics

May 21, 2013

Plastics for Medical ApplicationsOur Ask the Experts link has been filled with questions about the use of plastics in the medical and bio-medical fields.   

There are lots of different plastics that can be used in these applications.  Common types of biocompatible plastics include PVC and Polyethylene, PEEK, Polycarbonate, PEI, Polysulfone, Polypropylene, Polyurethane, and Ultem.  Ultem, for instance, is great for sophisticated uses like respiratory devices and pumps.  Our inventory also includes amorphous plastics for applications where transparency is important, such as in tubing. 

When choosing medical-grade plastics, be aware of:
