Block on Ring Test Module Information

Module Features:

  • Rigid design to support mN to 5000 N loads
  • Dry and Lubricated tests
  • -50°C to 500°C temperature
  • Up to 50 Nm torque motors
  • In-line Torque measurement

Block on ring tester helps determine the coefficient of friction, wear, friction, rate of wear, volume wear, and EP. Including wear resistance of lubricants, greases, bearings, rings, and shafts. The test can run under a wide range of load, sliding speed, rotational speed and temperature.  The test setup typically involves a block loaded against a rotating shaft or ring.

Rtec Instruments’ block on ring tribology module allows several ASTM and customized tests on the same platform.  We support the rotating shaft on both ends to prevent bending under high loads. The versatility of the block on ring module allows real components including shafts, power transmission components, tapered roller bearings, thrust bearings, and their counterparts mount with little modifications.  Computer controlled applied load, speed of rotation, test temperature, and lubricant flow rate creates highly repeatable results.

Test Data and Analysis

9
Wear Tests

The test analyses friction and wear characteristics of greases or oil in sliding applications on block on ring test machine. Pumps circulate and control lubricant and grease flow rates. These tests are configured by defining the temperature, loading rate, test load, rotation speeds.

Extreme Pressure EP Tests

This procedure covers the determination of the extreme pressure properties of lubricating oil or greases in sliding applications. The test involves increasing load step or linear mode until a seizure or sudden increase of cof change occurs. The Timken method tests grease and lubricants (ASTM D2509 and ASTM D2782).

Custom Tests

Rtec Instruments’ block on ring tribometer performs many customized tests, such as oscillating tests where the rings oscillate clockwise and counter clockwise to a pre-determined angle or number of rotations. These tests are frequently performed to evaluate the performance of solid lubricants, coatings or surface texture on bearings, and applications where there is frequent change in direction or limited motion between the two counterparts.
