6904 6904CE Full ZrO2 Ceramic Bearing 1PC 20x37x9 mm P5 6904RS Double Sealed Dust Proof 6904 RS 2RS Ceramic Ball Bearings

BearingsBearingProperties of Full Cearmic MaterialsCeramic Bearings, including components made from ceramic, have the special properties that steel bearings do not have, such as being non-magnetic or insulating. They can be used in new applications where conventional bearings have not been practical.Ceramic Bearings are highly heat resistant, enabling a rolling bearing to be practical in a high temperature environment. The low density of ceramic decreases the centrifugal force induced by rolling elements (balls or rollers), contributing to an increased speed of the apparatus.Model Number: 6904-2RS BearingMaterial: Full ZrO2 CeramicBearing Type: BallFor Load Direction: RadialConstruction: Single RowSeal Type: Two SealedPart Number: 6904For Shaft Diameter: 20mmBore Dia (d): 20 mmFor Housing ID: 37mmOuter Dia (D): 37 mmWidth (B): 9 mmRing Material: ZrO2 CeramicBall Material: ZrO2 CeramicCage Material: PTFESealed Material: PELubrication: NO GreaseShaft Mount Type: Press FitTemperature Range: -20 to 350ABEC Rating: ABEC-5Radial Clearance Trade No.: C0Widely used in household appliances, garden machinery, outdoor vehicles, industrial production, etc. Suitable for skateboards, longboards, inline skates, scooters, robots, ship rudder axles, etc.Features: small friction, fast speed, smooth, low noise.
