Block-on-Ring Tribometer - 3000N (High Speed)
Block-on-Ring Tribometer - 3000N (High Speed) - ToronTribo™ BOR 3000
High-speed block-on-ring tribometer evaluates lubricant performance and material wear resistance under oil-immersion lubrication at elevated sliding speeds, serving lubricant formulators, metal component manufacturers, and materials testing laboratories. The ToronTribo™ BOR 3000 presses a stationary block against a rotating ring while the contact remains fully immersed in the test oil, reproducing the flooded lubrication conditions found in bearings, gears, and other continuously lubricated sliding contacts.
The tester applies up to 3000 N of normal force with a maximum friction force of 300 N, and drives the ring at spindle speeds from 1 to 2500 rpm as standard, with an optional 2 to 4000 rpm high-speed configuration for accelerated test protocols. Test oil temperature is controllable from room temperature up to 100°C, and the main spindle rotation counter displays up to 9,999,999 revolutions, supporting long-duration wear and lubricant evaluation studies.
Lubricant manufacturers use the ToronTribo™ BOR 3000 to measure extreme-pressure properties under the Timken test method, while metal component producers and materials laboratories use the same platform to rank sliding wear resistance of metals and coatings under flooded lubrication. The shared block-on-ring configuration lets both applications run on a single, well-characterized test platform.

Theory and Method
Extreme-pressure lubricant testing and sliding wear ranking both rely on the same fundamental block-on-ring contact, but each measures a different outcome. The Timken extreme-pressure test method presses a stationary test block against a rotating ring while the lubricant under evaluation floods the contact, and the load is increased in steps until the lubricant film fails and scoring occurs on the block. The load at which failure occurs indicates how much pressure the lubricant can support before breaking down under boundary lubrication conditions.
The same block-on-ring configuration supports material wear ranking by holding load and speed constant while comparing wear volume across different block and ring material combinations. The ToronTribo™ BOR 3000 applies this principle through a spindle-driven ring immersed in a temperature-controlled oil bath, with load and friction force measured continuously throughout the test. Because the contact remains fully immersed in oil rather than run dry, the resulting wear and friction data reflect flooded lubrication behavior rather than the boundary or mixed lubrication conditions seen in dry sliding tests.
Running tests at elevated spindle speeds, up to 4000 rpm in the optional high-speed configuration, shifts the contact toward hydrodynamic lubrication conditions where a thicker oil film can more fully separate the block and ring surfaces. Comparing results across the standard and high-speed configurations lets engineers see how sliding velocity affects both lubricant film formation and the resulting wear or extreme-pressure performance, information relevant to both lubricant formulation and component design for high-speed machinery.
