MRS-10W four ball friction testing mac
Product name：MRS-10W Microcomputer control four ball friction testing machine
Product introduction
The machine mainly with sliding friction form, under high contact pressure conditions to assess the lubricant carrying capacity, i.e., the maximum nonseizure load Pb, sintering load Pd, wear zmz value etc.. The machine can also long wear performance test, the determination of friction, the friction coefficient calculation, connected to a computer, test records - friction curve, the temperature time curve, friction force time curve. The machine with high precision measuring device, friction measurements side grinding spot size and friction wear spot computer screen shows that measure and record.
This machine applicable standard1. Determination of extreme pressure performance of GB/T12583-98 lubricant (four ball machine method)
2. Determination of bearing capacity of the GB/T3142-82 lubricant (four ball method)
3. Determination of the SH/T0189-92 lubricating oil anti-wear performance (four ball method)
4. The grease SH/T0202-92 extreme pressure performance determination (four ball method)
5. Determination of wear resistance - SH/T0204-92 grease (four ball method)
