Frequently Asked Questions

The rubber seals prevent dirt, sand, dust and moisture from entering the bearing, which maintains smooth operation and extends bearing life substantially. Open bearings will accumulate contamination quickly and performance will degrade noticeably, especially when driving in outdoor environments or challenging terrain.

These specific bearings are standard components on many popular Traxxas vehicles.
• How often should I replace my RC bearings? — With sealed bearings like these, replacement intervals depend on usage intensity and driving conditions. Recreational drivers may go several seasons before needing replacement, whilst competitive racers or users in very dusty environments might replace bearings more frequently.
