Unbleached medium-weave cotton fabric makes this one of the most popular phenolic laminates. Strong and tough, with outstanding compressive strength and good machinability. Excellent wear and abrasion resistance with low coefficient of friction. Also stocked with graphite addition (Ryertex CG), reducing the need for lubricants.
Combines good tensile strength and high compressive strength with Class A electrical insulation values and low water absorption. Easy to machine. Medium weave, bleached cotton fabric.
Grade CG performs well in applications where oil or grease lubrication is maintained. The internally dispersed graphite aids lubrication and wearabllity compared to grade C. Ideal for pivot or king pin bearings in construction equipment and machinery. Ryertex grade CG is black in color.
Outstanding mechanical properties from medium weave fabric base and epoxy resin. Impressive 55000 psi tensile strength and 65000 psi compressive strength. Class B electrical insulation at temperatures to 325°F. Low water absorption.
A finer weave cotton fabric with 40% higher tensile strength than CE. Great for smaller electrical parts requiring more intricate machining. Class A Insulation with low moisture absoprtion.
JTR 726 is a laminated phenolic material that is manufactured using a combination of a paper based core and a woven glass fabric on both sides. This thermoset material has a smooth, glossy, resin-rich surface on both sides that machines or routes to a very fine finish.
Ryertex SBE60 consists of multiple plies of a 24oz/syd, heavy weight canvas saturated with phenolic resin and modified with molybdenum disulfide that provides internal lubrication to reduce friction, wear and heat generation. Molybdenum Disulfide is the lubricant of choice when electrical or static discharge is of concern since it is non-conductive. SBE60 offers exceptional load bearing capacities equal to brass and bronze bearings. Like all phenolics, SBE60 will not seize in bearing houses which reduces changeover times. Compared to thermoplastics, SBE60 prvides superior load-bearing properties and has a coefficient of thermal expansion that more closely matches metal shafts for bearing applications. SBE60 is often used for staves in water-cooled bearings
Ryertex SBE70 consists of mulitple plies of a 24oz/syd, heavy weight canvas saturated with phenolic resin and modified with alumina which adds hardness to the material. This material provides increased wear resistance and is ideally suited for heavy, industrial bearing applications. SBE70 offers improved load bearing capacities over SBE60 and is equal to brass and bronze bearings. Like all phenolics, SBE70 will not seize in bearing houses which reduces changeover times. Compared to thermoplastics, SBE60 provides superior load-bearing properties and has a coefficient of thermal expansion that more closely matches metal shafts for bearing applications. SBE70 is colored red for easy identification and inspection of bearing surfaces.
