SGW-10G Touch screen computer control lever-loading four-ball friction tester
Brief introduction：SGW-10G lever-loading four-ball friction testing machine is used for the
One.Product Description：
The SGW-10G lever-loading four-ball friction testing machine is a cost-effective laboratory evaluation equipment developed by our company to meet the needs of lubricant development and production users.In the form of slide friction, it is used for the loading capacity evaluation of lubricants in the high pressure point contact condition. It can test the maximum nonseizure load PB, sintered load PD and composite wear value ZMZ of lubricants .The four-ball friction test machine can also be used as lubricant for long time wear resistance test, determination of friction coefficient, recording friction and temperature curve. It also can measure the dimension of the wear scar and display,measurement and recording the wear scar on the PC screen.The wear resistance of metallic materials or non-metallic materials can also be studied with special attachments.
The product is suitable for the following standards:
ASTM D2266-01 Test method for friction and wear of lubricating oil (four-ball method)
ASTM D2783-2003 (2009) four-ball bearing capacity of four balls of lubricants
ASTM D2596-2010 Test method for extreme pressure performance of grease (four ball method)
GB/T12583-98 Determination of extreme pressure performance of lubricants (four-ball machine method)；
GB3142-82，Determination of the carrying capacity of lubricants (four-ball method);
SH/T0189-92，Determination of oil abrasion resistance (four-ball machine method);
SH/T0202-92，The method of determination of extreme pressure of grease (four-ball machine method);
SH/T0204-92，Determination of resistance to abrasion of grease (four-ball machine method).
