Lubrication

Sinclair, in cooperation with USBM. Describes theory of friction and the application of lubricants. Illustrates useful friction, such as wheel traction and braking systems. Shows vari- ous types of oil for different uses; range of petroleum lubricants in six main classes: 1. spindle oils to lubricate machinery with high speed, but little pressure; 2. internal combustion engine oils; 3. gear oils; 4. steam cylinder lubri- cants; 5.greases for heavy-duty, slow moving machines; 6. machine tool lubricants used in cutting metals.
