Smooth Spin for RC Car
Great bearings for my 1/10 scale buggy. Very smooth rotation and noticed less friction immediately after installation.

Perfect Fit for Drones
Fit my drone motors perfectly. The ceramic option is lightweight and handles high RPMs without overheating.

Good Quality Import
Fast shipping via SF Express. Quality seems genuine Japanese import. One seal was slightly tight but loosened up after use.

Reliable Purchase
Good product, packaging was secure. Would prefer if grease type was specified on the box, but overall satisfied.
Q: How long does SF Express shipping take?
A: Typically 3-5 business days depending on your location and customs processing.
Q: Are these bearings pre-lubricated?
A: Yes, all bearings come factory pre-greased for immediate use out of the package.
Q: What is the difference between ZZ and 2RS seals?
A: ZZ offers metal shields for less friction, while 2RS offers rubber seals for better dust and water protection.
Q: Which size is standard for 1/10 scale RC cars?
A: Usually the 608 model is standard for 1/10 scale wheels and motors.
Q: Can ceramic bearings be used in wet conditions?
A: Ceramic resists corrosion better than steel, but we recommend sealed versions for wet environments.
