Tamiya 42193 TRF Tungsten Thrust Bearing Balls 8pcs - Durable Upgrade  [42193]

Tough Tungsten Bearings for TRF Systems

Tamiya's tungsten thrust bearing balls (part number 42193) are designed to reinforce the thrust bearing assembly in TRF differentials. The tungsten construction offers greater resistance to wear than common steel balls, helping the bearing maintain smooth rotation under load.

Compatible TRF Chassis

These balls are suitable for several Tamiya TRF models, including TRF416, TRF416WE, TRF416X, TRF417, TRF201, TRF511, and TRF502X. They are a good fit for racers and hobbyists looking to reduce thrust wear on their vehicles.

Durability and Maintenance Benefits

Because tungsten is harder and more wear resistant, you can expect fewer replacements and steadier performance from the thrust bearing. That means less frequent teardown and more time driving.
