Wheel Bearing ToolsRadial clearanceThe size of the radial clearance will affect the producteffect.Radial clearance is represented by C.<;C0C3C2= 3-8u;CO=9-14u;C3= 15-25uDetermine a more suitable clearance based on your product.The smaller clearance makes the rolling without shaking and swing-ing, which can keep the product in a straight line state when rolling.Larger clearance increases the ultimate rotation speed of thebearing.GreaseGrease can lubricate bearings, and different grease willhave different density and temperature resistance limit.Good grease will improve performance, reduce noise,(increase smoothness, lightness and service life.Our carbon steel bearings generally use Great Wall grease,bearing steel Z1 grade uses Snow grease, whileZ2/Z3/Z4 grade uses imported Union grease.The company supports customers to customize non-standard bearings.Dust coverThe letter behind the bearing model number indicates that thebearing seal cover (dust cover) can be divided into three types.ZZ or Z indicates that the metal cover is sealed and used in occa-sions with good external environment and high speed requirements.2RS or RS indicates that the plastic cover is sealed withgood sealing performance and strong dustproof capability.OPEN or no letter indicates "OPEN" no dust cover is suitablePlaces that require high speed or fast idling.Radial clearance==========Material : Bearing SteelModel Number : R2 R3
