Abstract Polytetrafluoroethylene (PTFE) is widely used in tribological applications. However, its usage the ball-bearing application has not been explored. The present study investigates of PTFE composites for deep groove ball (DGB) bearings. Initially, a ball-on-disc experiment conducted to analyze interaction between pure PTFE, 40% bronze-filled, 25% glass fiber-filled composites, and Si 3 N 4 balls by determining coefficient friction (COF) specific wear rate. Then, reliability fabricated DGB checked through free run rolling contact fatigue (RCF) tests using 6-channel DAQ system (OR35-INST). In test, rotor supported on polymer bearing sets rotated up two million cycles under minimal load conditions. Its vibrational signals RPM are continuously monitored an accelerometer tachometer. After subsequent number cycles, dynamic characteristics shaft recorded eddy probes. Finally, RCF test check load-bearing capacity bearing. subjected 36 108 (in step N) load, vibration recorded.
