    1. Four Ball Friction & Wear Testing Machine
      Contact Us
    2. Four Ball Friction & Wear Testing Machine The four-ball tribometer is used to determine the friction and wear properties of lubricant, including oil and grease, under varying load conditions. It accurately assesses the load-bearing capacity of lubricants through several key metrics: maximum non-seizure load (Pb), sintering load (Pd), and comprehensive wear value (ZMZ).

    1. Shear Stability Testing Machine
      Contact Us
    2. Shear Stability Testing Machine The tapered roller bearing shear test (KRL test) is a specialized method designed to assess the mechanical stability of lubricants under high shear conditions. Conducted according to the DIN 51821 standard, this test evaluates a lubricant’s ability to maintain its consistency (shear stability) over extended periods of use. It is especially suited for lubricants that must endure extreme mechanical shear and high temperatures.

    1. Gear Wear Testing Machine
      Contact Us
    2. Gear Wear Testing Machine Our gear wear testing machines are designed to evaluate the performance of lubricants and gears under load-bearing conditions, focusing on the fatigue strength and wear of gears. Developed for both gear oil research and gear material testing, it complies with the German DIN51354 standard for lubricant testing.
      Max. torque 1000N.m
      Load level 12 level
      Rotation speed 0-3000r/min (stepless adjustable)
      Test oil temperature 90±3℃
      Motor type Servo motor

    1. Tapping Torque Testing Machine
      Contact Us
    2. Tapping Torque Testing Machine The tapping torque tester evaluates the performance of metalworking fluids and lubricants. It uses a standard sample tap to cut into a standard nut blank filled with cutting fluid at a controlled speed, measuring the torque generated during the process. By comparing the torque ratio between a reference fluid and the test fluid, the lubrication performance of the cutting fluid can be accurately assessed.
      Spindle output torque range 0-10N.m/0-25N.m
      Max. limit torque (non-cutting extrusion state) 50N.m
      Relative accuracy of torque measurement indication ±1%
      Verify torque accuracy ±0.3%
      Spindle stepless speed regulation range 5-1000r/min

    1. Lever Type Four Ball Friction Testing Machine
      Contact Us
    2. Lever Type Four Ball Friction Testing Machine Our lever-type four ball friction tester are tools used for evaluating the performance of lubricants under high-pressure conditions, specifically their load-bearing capacity and resistance to wear. By simulating extreme point contact pressure with sliding friction, the testerhelps determine how well lubricants can protect gears and other mechanical components under stress.
      Max. test force 10000N
      Relative accuracy (below 4% of test force) ±5N
      Relative accuracy (above 4% of test force) ±1％
      Test force loading method Manual loading of weights
      Force holding mechanism Self-balancing backlash-free guiding
