Description

This device appears as Device Number 211 in the ASLE Friction and Wear devices book and was
originally developed by NTN in the 1960s.
The RCF 8 is designed for evaluating rolling contact fatigue (RCF) performance under high-speed
and high-load conditions. It features a 12 mm rod specimen loaded against a 60 mm motordriven roller using two 20 mm diameter balls, which are supported and guided by profiled rollers.
A pneumatic actuator applies up to 4 kN of load, generating contact pressures up to 6 GPa.
With a 5:1 drive-to-test roller ratio, the test roller can reach 30,000 rpm, enabling rapid fatigue
testing for high-throughput data collection. A compact servo motor ensures precise speed control,
while the touch-screen interface allows for easy operation with minimal training. Designed for
bench mounting, the rig is space-efficient and ideal for fatigue life assessments of bearing steels.

Features

• Wide Speed Range: 100 – 30,000 rpm
• High Load Capacity: Up to 4 kN
• User-Friendly: Simple touch-screen operation
• Compact Design: Bench-top mounted for space efficiency
• Cost-Effective: Reliable RCF testing at an affordable cost

The only measured parameter is vibration. Tests run for a set duration, cycle count, or
until specimen failure, detected by a vibration sensor on the test assembly.
