GE20C bearing is Spherical Plain Bearing Ball Joint bearings are appropriate for bearing arrangements where alignment movements between the shaft and housing have to be accommodated, or where oscillating or recurrent tilting must be allowed at comparatively slow sliding speeds.
Lining: Comprised of PTFE, tin bronze and sheet steel backing.
Inner ring: Bearing steel, through hardened and ground, sliding surface hard chromium plated.
Outer ring: Steel backing with PTFE sintered bronze layer pressed around the inner ring, with a butt joint
Permissible operating temperature range: -50 to +150°C, for short periods up to +280°C, reduced carrying capacity above 80°C
Lubrication: self-lubricating; the bearings must not be lubricated Steel against PTFE sintered bronze
