SH120 Automatic four ball machine
SH120 Fully Automatic Four-Ball Machine Lubricant Wear Resistance
Tester evaluates the load-carrying capacity of lubricants primarily
through sliding friction under extremely high point contact
pressure conditions. It includes three key indicators: maximum load
without seizure (Pb), scuffing load (Pd), and comprehensive wear
value (ZMZ). In practical applications, different evaluation
indicators can be selected based on the various uses of lubricants.
This four-ball friction tester can also conduct long-term wear
resistance tests for lubricants, measure friction coefficients, and
record friction force and temperature curves.
With the use of special attachments, it is also possible to conduct
simulation tests for end-face wear and material performance. The
machine's design principle incorporates the loading stability of
the lever-type four-ball machine while integrating the
characteristics of servo valve loading. Through a servo motor, air
spring, and closed-loop control software, it achieves automatic
zeroing, loading, holding, testing, unloading, measurement of wear
scar diameter, and photography with a single button operation. Data
storage is also one-click, enabling fast testing speeds, minimal
error, excellent repeatability, pollution-free operation,
noise-free performance, and high efficiency.
