Featured Wheel Bearings:
Straight Roller Bearings - traditional anti-friction bearing, best for manual applications where shock loading (but no side thrust) is prevalent.
Precision Ball Bearings - double sealed, maintenance free, superior rollability aids manual applications, bot recommended if shock loading is prevalent.
Oilless Sleeve Bearings - sintered iron, practical for light loads
Plain Bore - suitable for light or seldom moved loads, where ease of starting and rolling is not too important
