Original Press Release:
Filament-Wound Plain Bearings for Extreme Loads, Slow Movements
Thorofare, N.J., March 2004 - GGB, formerly Glacier Garlock Bearings, now offers High-Strength GAR-MAX. filament-wound dry bearings, which can withstand even higher compressive loads than its standard GAR-MAX bearings. Improvements in the patented structure and composition of GAR-MAX, until now the best-performing fiber/resin composite bearings available, have resulted in optimum strength properties, allowing a 50% increase in load-carrying capacity.
The new bearings exhibit good friction and wear properties under slow speed oscillating or rotating movements, as well as resistance to shock loads and chemicals. These properties make them especially suitable for applications such as construction and earth moving equipment, conveyors, agricultural equipment, railway couplers, chemical plant valves and others.
Available as cylindrical bushes, High-Strength GAR-MAX can withstand maximum static specific loads of up to 43,500 psi (300 MPa) and dynamic loads of up to 20,000 psi (140 MPa). Maximum recommended speed is 25 fpm (0.13 m/s). Maximum pU factor is 40,000 psi x fps (1.4 MPa x m/s). Operating temperature range is -148°F to +320 °F (-100 °C to +160 °C). Coefficient of friction (f) is 0.05-0.30. Recommended shaft surface finish RA is 0.2-0.85m. Recommended shaft hardness is >200 HB and preferably >350 HB for a service life >2,000 hours.
