GFKGFK Series Sprag One-Way Clutch Bearing, 59-series dimensions
GFK One-Way Bearing TIANIU
GFK is a Tianiu sprag one-way bearing with its own roller and ball support in the envelope of 59-series bearings (5904–5910): the design gives the highest torque for the smallest outer diameter. There are no keyways — torque is transmitted by an interference fit only: housing R6, shaft p5. 7 sizes for 20–50 mm shafts: nominal torque 41–240 N·m (peak 2.5 × TKN), inner race overrunning speed up to 5,500 rpm, outer race up to 4,000 rpm. Grease lubricated; operating temperature −40…+100 °C, briefly up to +120 °C.
