Race-Focused Bearing Upgrade

The 3RACING Double Metal Shield Bearings 1/4 x 1/2 x 3/16 (10 pcs) - 3RB-R188-ZZ/10 are specified to reduce rotational drag in key drivetrain positions. These sealed bearings support repeatable lap times by minimising variability from worn running surfaces.

Durable Shielding and Consistent Operation

Each bearing features a double metal shield to limit ingress of track debris and to help retain lubricant under varied RPM and load. The predictable running characteristics make setup and tuning more straightforward during race weekends.

Application and Fitment for Tuners

The standard 1/4 x 1/2 x 3/16 dimensions fit common axle and hub locations, allowing quick swaps during chassis prep. Use this ten-piece set when optimising bearing endplay and reducing drivetrain losses.

What bearing locations benefit most from these shields?

Wheel hubs and idler shafts see immediate gains in consistency, as the shields reduce contamination that can change bearing drag between runs.

Are these suitable for high RPM race motors?

Yes, when fitted correctly and lubricated with a light bearing oil, these sealed bearings perform well at high rotational speeds common in racing classes.

How should I approach bearing choice for a race setup?

Prioritise tight running clearance, confirmed fitment to the 1/4 x 1/2 x 3/16 seats, and consistent lubrication practice to keep lap times repeatable.
