Performance Sealed Bearings for Tuning

The 3RACING Double Rubber Seals Bearing 3RB-R166-2RS/10 at 3/16 x 3/8 x 1/8 inches is a compact upgrade that reduces contamination while retaining consistent preload and rolling feel. Ten bearings in the pack allow a full hub and drivetrain service for many touring and off-road setups.

Sealing and Service Intervals

Rubber seals block ingress of abrasive particles and light moisture, extending service intervals and maintaining predictable resistance in the bearings. For competitive tuning, consistent bearing drag helps with throttle control and lap time repeatability.

Recommended Fitments

Use these seals in wheel hubs, differential carriers and idler shafts where a sealed bearing is preferred to reduce maintenance. They are suited to club racing and practice where durability and low upkeep are priorities.

What is the internal clearance expectation?

Factory assembled sealed bearings typically have a standard internal clearance suitable for general RC use; measure fit and adjust preload as required for your chassis.

Should I relubricate for competition?

Many racers relubricate with a lower viscosity oil for reduced rolling resistance, but seals will retain the lubricant longer than open bearings.

Can these bearings handle shaft misalignment?

Sealed radial bearings tolerate minor misalignment but significant angle error is best handled by using appropriately sized housings or flexible couplings.
