Sealed Bearing Protection from 3RACING 3RB-MR104-2RS_10

The 3RACING Double Rubber Sealed Bearings 4x10x4mm (10 pcs) - 3RB-MR104-2RS_10 use two rubber seals to keep dust and moisture away from the race and ball set. Their compact 4x10x4mm size suits numerous small-scale RC locations where contamination can shorten bearing life.

Applications Across Models

These bearings work well in lighter on-road cars and many compact off-road builds. The sealed design is especially useful for weekend track sessions or park practice where grit is common.

Sealed Design Advantages

Double rubber seals reduce the need for frequent cleaning and preserve internal lubrication, which helps maintain smooth rotation under everyday hobby use and moderate competition.
