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

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 material

More durable

Higher precision

Tips for Maintaining Old Ball Bearing: 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.

High Speed Bearing Oil / Lube (YA-0215) Universal Cleaning Case (YA-0223) Aluminum Bearing Inner Size Measurer

Step 1: Cleaning

Soak the ball bearings with volatile degreaser (i.e. brake cleaner) / apply motor spray on them.

Step 2: Shake & Soak

Shake 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: Drying

Dry the ball bearing with hot air gun / hair blower to prevent rusting of the bearing.

Step 4: Re-greasing

Apply light oil on the bearings, give it about 20 minutes to penetrate the seals and then clean the outsides up.

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.
