Pillow Blocks
Special bearings for artistic roller skates!
Five ball design High speed Wear and heat resistant!
(1) Selected 5 G5 grade zirconia ceramic balls to reduce deflection waterproof wear resistant acid and alkali resistant high temperature resistant resistance to electrical insulation repeatedly polished chute is smoother and faster. The single-sided stepped dustproof design reduces dust and sand intrusion.
(2) Bearing steel has high hardness tensile strength considerable toughness and contact fatigue resistance wear resistance certain high temperature resistance; bearing steel material in the oxygen content of the formation of non-metallic impurities significantly reduced effectively reduce noise improve torque and doubled the bearing life.
Uses for:
For Art skates skates roller skates various mechanical equipment precision instruments food machinery sliding doors; 3D printers etc.
