Tech Tip: Advantages of Reinforced Plastic Bearings

May 1, 2014

The advantages of reinforced plastic bearingsI recently made a site visit to an engineer who was reluctant to consider replacing metal bearings with plastic.  It seems in some industries, there is still a (mistaken) belief that plastic bearings are not as durable as metal in extreme applications.  In this case, I shared TriSteel, our premier reinforced plastic bearing component.   TriSteel consists of a steel backing bonded to a polymeric liner, and delivers superior performance and wear without the need for regular lubrication.

TriSteel bearings rule the lawn

August 30, 2011

In this season of backyard lawn maintenance and gardening, I’ve been reminded of our long partnership with the manufacturers of riding lawn mowers.  One client approached us for a replacement option for the steel bearings on the undercarriage and steering components of their riding mowers.  As steel prices escalated, steel bearings were becoming cost prohibitive – plus the bearings were not providing the season-to season longevity they needed due to the lack of good maintenance.

Q & A: Do you know where I can get Dixon M-Liners or an equivalent product?

February 1, 2010

The Dixon M-Liners from Saint Gobain have become very difficult to obtain since they come from overseas. Tri Star is now offering a size for size equivalent product in it's Tri Steel product line called Tri Steel PE. This product is a rolled steel backed polymer lined bearing. The polymer liner is a special PEEK/PTFE combination that has a thicker dimension than normal steel backed bearings. This allows for post machining of the ID to tighter tolerances without removing the primary bearing source. Learn more from Tri Star's website www.tstar.com and review the information on Tri Steel Bearings or watch our Tri Steel video on the Video Learning Center.

Metal Backed Bearing Uses Modified PEEK Liner

June 2, 2009

New TriSteel PE material utilizes the outstanding wear properties of PEEK, combined with the PTFE low friction additive, make this product unique in thin wall metal backed products. The PEEK liner has excellent resistance to chemicals and when combined with a stainless steel shell material it is perfect for applications in chemical pumps, valves or environments where temperature is critical. TriStar's TriSteel PE bearing is available in inch and metric sizes as sleeve, flange and thrust bearings. Ask the Experts or visit www.tstar.com for more information.
