Product Description

Composite 4 Ball Tester

We have a strong foothold in the market as a prestigious manufacturer and supplier of a wide array of Composite 4 Ball Tester. It is manufactured using certified components to make sure that best quality product reach our clients. Also, we perform stringent test on the manufactured tester to ensure zero defect in it. The instrument is easy to operate and reliable. Furthermore, our Composite 4 Ball Tester is widely used in petroleum industry, automobile industry, laboratories, and research institutes for the testing of lubricants.


  • Driven by a Host PC
  • Automatic Functionality
  • Convenient to Operate
  • Durable & Reliable

The PC based 4 Ball Tester is a completely automatic, PC based analytical instrument used for conducting and recording the results of 4 Ball tests of lubricants. The refined design of the mechanical load arm, coupled with imported sensors and a state of the art digital circuit ensures high speed data acquisition, which in turn is feed into the PC based software running on a host PC for analysis. It provides accuracy, repeatability and reliable test results to ensure proper testing of samples and this system has the unique feature of displaying Real Time graph of Time Elapsed v/s Frictional Force. The design has high degree of automation to ensure minimum human intervention.

Loading arm and chuck:

The upper single ball is hold on a special rotating chuck, connected to a variable speed motor (Speed to be set as per the test). The lower 3 balls are fixed on a round chuck capable of being filled with lubricants/ lubricating oil as required and these balls are not allowed to rotate. This chuck for the lower ball is set on a self-aligning bearing to ensure that the rotating ball is in the exact centre of the fixed 3 lower balls. The loading arm is fixed so that it exerts an upward pressure on the lower fixed chuck depending on the load on the arm. The frictional force of the rotating ball with the 3 stationery balls is measured by a load cell fixed to the stationery chuck.

Data acquisition and software:

The load cell and the motor are controlled by a dedicated software (Windows based software, and provided by us) running on a Host PC. Once the tests are started the High speed data acquisition system connected to the load cell feeds the frictional force data, to the software for further analysis as mentioned below.

Operating Procedure:

a) The user has to fill the lower chuck with the lubricant, and fix the lower balls using the special tool to tighten the splash guard and oil circulation jacket
b) The load arm is manually loaded with weights provided.10 to 800 kgs.
c) The operator has to key in the Test Number (ASTM/IP): in the GUI of the dedicated Software. The apparatus automatically sets the speed and duration of run. (This saves the user from the trouble of entering the test criterion e.g. RPM, time for test, end test criterion, etc.) each time the test is conducted. The operator also enters the Lot Number and other test parameters to identify the test.
d) The dedicated software sets up the parameters for the tests e.g.

Instrument capable of conducting the following

ASTM Test.


ASTM D 4172: Standard Test for wear preventive Characteristics of lubricating oil.

Temp: 750C
Speed: 1200
Duration: 60 minutes
Load: 15 or 40 Kgf.

ASTM D 2783: Measurement of extreme pressure properties of lubricating fluid

Speed: 1760 r.p.m.
Temp: 350C
Duration: 10 Seconds

ASTM D 5183: Measurement of coefficient of friction of lubricants.

Seed: 600 r.p.m.
Load: 40 Kgf. /10 Kgf.
Duration: 60 minute/10 minutes

IP 239: Determination of extreme pressure and anti-wear properties of lubricants.

Speed: 1405-1500 r.p.m.
Duration 10 or 60 seconds.

e) The test is started by clicking on the start button and the system does the following:-

  • The motor starts at the pre-set RPM and the software displays RPM Real Time.
  • The machine records the frictional force for appropriate tests and displays the graph in the PC Real Time.
  • The end criterion is set, so that the machine automatically shuts down at the onset of seizure or after pre-set period.
  • On completion of test, the computer displays the result, along with the graph (if applicable). The result is stored in data repository in the hard disk. The results can be retrieved afterwards for printing, with date and time stamp.
  • The scar diameter has to be manually measured by the microscope provided.

Salient Features:

  • Rigid Test Rig: Rotating shaft /arbour holding the rotating ball chuck is supported on dual angular contact bearings for Mech. Stability and low run out.
  • Test parameter repository: The system contains a pre-defined set of data for each test method, giving flexibility and speed in testing. No manual intervention to set up test parameters eliminating possibility of human error.
  • Real Time Data Acquisition: The system contains a data acquisition device, which captures the test results and feeds the computer on a real time basis during the test.
    • On-screen Test Results: Test results are all displayed in the screen real time
    • Time v/s. Torque (Data & Graph): Clicking on the graph gives the details
    • Seizure Time
    • No. of Cycles
  • Test Result Database: The test results are stored in a database in the hard disk of the computer for the complete test.
