Change the sample and use 4 balls for each test, repeating until fusion occurs! A test to measure the load-bearing capacity of grease.
We would like to introduce our "Shell Four-Ball Test: LWI/WL/ISL Grease." Four steel balls are stacked in a pyramid shape, and a sample is placed in a container. The top ball is rotated under specified conditions, and the test is repeated with different balls and samples until welding occurs. The maximum non-seizure load (LNL), initial seizure load (ISL), and welding load (WL) are determined, and the load wear index (LWI) is calculated and evaluated. 【Test Details】 ■ Item Number: G390 ■ Required Amount: 300g ■ Standard Number: ASTM D2596 ■ Target Oil Type: Grease *For more details, please refer to the PDF document or feel free to contact us.
