BEARING LINER MATERIAL<br />
Simplicity bearings are available with three liner materials.<br />
FrelonGOLD is a dark gold colored high performance material<br />
with gold-colored fi llers and is compatible with standard<br />
RC60 hardened steel shafting, RC70 ceramic coated Feather<br />
Shafting and 440 stainless steel shafting.<br />
Frelon J is a yellow colored material specially formulated to<br />
provide the optimum performance with 300 series stainless<br />
steel and softer shafting like bare aluminum.<br />
RUNNING CLEARANCE<br />
Simplicity bearings are available with two classes of running<br />
clearance.<br />
PRECISION–“FL”:<br />
• Performs like a preloaded ball bearing<br />
• Tightest running clearance approximately .001" (.025mm)<br />
• Use in applications that require high precision<br />
CAUTION: Not recommended for all parallel shaft<br />
applications. Any misalignment can cause binding on the<br />
shaft. See recommended “FLC”.<br />
COMPENSATED–“FLC”:<br />
• Performs like a standard ball bearing<br />
• Additional clearance built into the I.D. (all other dimensions<br />
are the same as the precision bearings)<br />
• Ideally suited for parallel shaft applications<br />
NOTE: Many parallel shaft applications will run “FL” precision<br />
on one rail and “FLC” compensation on the opposite rail to<br />
accommodate slight misalignments.<br />

BEARING SHELL<br />
Simplicity bearings are available in a variety of configurations<br />
to help meet specific application needs.<br />
• Standard is aluminum alloy with anodized<br />
fi nish (standard)<br />
• Special 316 stainless steel (no plating) (optional)<br />
