HRATF125C11 - Center Driveshaft Bearing 11x21x4

Precision radial bearing designed for use as a center driveshaft support in RC vehicles, featuring an 11 mm inner diameter, 21 mm outer diameter, and 4 mm width. The bearing supports the center driveshaft to reduce vibration and friction while maintaining smooth rotation and alignment under load. Hardened steel construction with sealed shields ensures durability and long service life in high‑speed or high‑load drivetrain applications.

• hardened steel races and balls for high load capacity and long life

• 11 mm inner diameter fits common driveshaft support studs and hubs

• 21 mm outer diameter and 4 mm width sized for mid‑drivetrain bearing locations

• sealed shields keep dirt and debris out to maintain smooth rotation

• low friction design reduces drivetrain drag and improves efficiency

• precision tolerances support smooth power transfer at high RPM

• suitable for center driveshaft support positions in 1/10 and similar scale RC vehicles
