Yeah Racing YB6013B/S10 RC PTFE Bearing 5x10x4mm 10pcs

Yeah Racing RC PTFE Bearing (5x10x4mm) 10pcsFeature:RC Ball bearings should always be your first upgrades, it reduces friction for less rolling resistance, and that means higher speed and longer the running times. RC Ball bearings hardly require maintenance and last a lot longer than stock Oilite bushings.Yeah Racing RC Ball Bearings have the lowest resistance. They are manufactured by Aircraft quality steel. Pre-lubricated to ensure its excellent performance!These high quality bearings outweigh the other low quality one:Aircraft quality materialMore durableHigher precisionSpecification:Yeah Racing (#YB6013BS/10) RC Telfon Bearing (5x10x4mm)Material: MetalInclude:Bearing (10Pcs)* Photo for Reference OnlyTips on Cleaning & Lubricating Ball Bearings (RC Bearing Tips)Tips for Handling New Ball Bearin Most competition RC racers will clean the grease on the new ball bearings and apply ball bearing oil on them. (i.e. Yeah Racing High Speed Bearing Oil / Lube #YA-0215). As re-oiling the ball bearing allows the RC cars to run smoother and makes the bearings more durable.Tips for Maintaining Old Ball Bearin By removing the old bearing oil, it will reduce the friction in the bearing, thus making RC car run faster. Below are some tips in cleaning the ball bearings.Preparation:  High Speed Bearing Oil / Lube (#YA-0215) Universal Cleaning Case (#YA-0223) Aluminum Bearing Inner Size Measurer For 2-14mm (#YT-0021)Step 1: CleaningSoak the ball bearings with volatile degreaser (i.e. brake cleaner) / apply motor spray on them.Step 2: Shake & SoakShake the bearing case vigorously to remove dirt. It will loosen and remove the dirt trapped inside the bearings. Soak the bearings for another 15-30 minutes. Repeat the process until the oil / liquid is clean.Step 3: DryingStep 4: Re-greasingDry the ball bearing with hot air gun / hair blower to prevent rusting of the bearing.Apply light oil on the bearings, give it about 20 minutes to penetrate the seals and then clean the outsides up.Finish:Bearing Testing Tool:This tool can test the smoothness of the bearing. Put the bearing on the tool and turn the bearing to check its smoothness. If the bearing does not turn smoothly, then it¡¦s time to get a new one.Aluminum Bearing Inner Size Measurer For 2-14mm (#YT-0021)
