The Fiber-Lube™ FT bearing is used for applications where a slightly higher surface velocity, when compared to the Fiber-Lube™ FW Series, is required. Similar to the FW Series bearing, the FT bearing is manufactured by a filament winding process that results in a continuous fiberglass filament backing composition-ensuring excellent mechanical properties (especially fatigue resistance) are attained. The filament wound fiberglass structure uses a high strength, corrosion resistant epoxy resin as the matrix material. The high strength backing permits the use of a thin wall (1/16" to 1/8") bearing which can often reduce the size and weight of the finished bearing assembly.

These differences are driven from the fact that the FT bearing uses a filled PTFE resin structure as opposed to the continuous PTFE filaments used in the FW product. Two liner thicknesses are available with the 0.015" thick liner being standard and a 0.030" thick liner being available for unique applications. The 0.030" thick liner is designed for applications where boring the inner diameter might be required in order to achieve tighter tolerances in an effort to address sizing and minor misalignment conditions.
