Polytetrafluoroethylene plastic multi-layer bearings with back metals [ Free) Test data Journal rotation test Feature • Serviceable without the need for lubrication. Thin and lightweight for compact design. • Demonstrate low coefficient of friction and superior load performances in high-load, low-speed conditions. • Usable at the high PV values even in the middle- and high-speed zones when lubricated. • Usable in wide temperature ranges from low to high temperatures. Has superior chemical resistance. • Features superior dimensional stability, mechanical strength, and thermal conductivity. • The standard products and plate materials are available in various sizes. Service range The values in parentheses are static bearing pressures, which are the bearing pressures in applications with no motion or very small motion (^0.0017m/s[0.1m/min]). ^Allowable max. pressure of LFCF is 24.5N/mm2 (250Kgf/cm2!. ^The values shown above are typical values, not the standard values. >8 The values shown above are values of back metal. <Testing conditions> Bearing dimension : 040X044X R 30 Mating material : S45C Pressure : 14.7,8.8, N/mm2 Test time[hrs.]

PTFE multi-layer bearings with back metals Press-fitting (Rolled bushing) Press-fitting jig Generally, as shown in the figure 1, a mandrel is used for the press-fitting. However use of a guide ring facilitates easier press-fitting. Use of a guide ring prevents damage of a bushing at the time of press-fitting, The dimension of a guide ring should be calculated from the table below. Inner diameter of the guide ring should be the size so that the bushing can be inserted by hands. Length of the guide ring should be more than one-third of the bushing, or if possible, it should be the same length as...
