*Rollers adopt C3 deep groove radial ball bearing which adopts bidirectional seal structure
to improve the performance of water-proof and dust-proofing.
*Brand: SKF/NSK/NTN/HRB/KOYO/IKO/THK/TIMKEN, etc.
(Make sure the quality of bearing)
It is seal and its relative motion parts don't contact, and there is proper clearance seal.
*Almost do not produce friction heat in the work
*No wear and tear, especially suitable for high speed and high temperature occasion.
*Forming a complex, winding and narrow maze between inner and outer seal part.
*The good performance of water-proof and dust-proof.
Rolling bearing lubrication purpose is to reduce the bearing internal friction and wear, prevent burning stick.The lubrication effect is as follows.
*Reduce the friction and wear
*To extend the fatigue life
*Discharge the friction heat and cooling
*To prevent foreign matter into the bearing internal, or to prevent rust and corrosion
