High-Speed End-Face Tribometer
High-Speed End-Face Tribometer - ToronTribo™ HS
High-speed end-face tribometer evaluates sliding friction and wear performance at elevated rotational speeds, serving seal manufacturers, materials laboratories, and component developers working with high-speed rotating equipment. The ToronTribo™ HS presses two flat end faces together under a controlled normal force and rotates one against the other at speeds well beyond typical end-face testers, reproducing the demanding sliding conditions found in high-speed seals and rotating machinery components.
The tester applies a normal force range of 20 to 2000 N with a maximum friction torque of 20 N·m, and drives the spindle from 100 to 5800 rpm with stepless speed regulation for precise velocity control across the entire range. Surface temperature is monitored up to 300°C, while a circulating oil tank controls test temperature from room temperature up to 200°C, letting engineers evaluate combined high-speed and elevated-temperature contact conditions. Microcomputer control integrates industrial computer technology, modular data acquisition, and network communication, with system software monitoring the test in real time and recording all relevant parameters and curves throughout the run.
Seal manufacturers, materials researchers, and component developers use the ToronTribo™ HS to characterize how face materials and lubricants perform under sliding velocities that exceed the range of standard end-face testing equipment. The combination of high speed and controlled oil temperature makes it suited to evaluating components intended for high-RPM rotating machinery where standard-speed testing would not reveal velocity-dependent wear behavior.

Theory and Method
End-face friction and wear testing evaluates materials using a face-on-face contact geometry, in which two flat surfaces press together under axial load while one surface rotates relative to the other. Sliding velocity at the contact interface increases directly with rotational speed, and as velocity rises, the contact can shift from boundary lubrication, where direct asperity contact dominates, toward mixed or hydrodynamic lubrication, where a fluid film increasingly separates the two surfaces. This shift changes both the friction coefficient and the wear mechanism at play, which is why velocity is a key variable to control deliberately in face-contact testing.
The ToronTribo™ HS applies this principle through a stepless variable-speed spindle drive that reaches up to 5800 rpm, far exceeding the speed range of standard end-face testers. A torque sensor measures friction continuously as speed increases, letting engineers observe how a material pair transitions between lubrication regimes as sliding velocity climbs. The circulating oil tank maintains a controlled temperature at the interface throughout this process, so that any change in friction or wear behavior can be attributed to velocity rather than uncontrolled temperature rise from frictional heating.
Because heat generation at a sliding contact increases with both speed and friction, high-speed testing places additional demand on temperature control compared to lower-speed tests. Monitoring surface temperature separately from the circulating oil temperature lets engineers see how effectively the lubrication system manages heat at the contact as speed increases, information directly relevant to designing seals and rotating components that must maintain performance at sustained high rotational speeds.
