Hobbywing Motor Bearing Front For Xerun 3652/3660/4268/4274

The Hobbywing Motor Bearing Front (HW30820028) is a high-precision, heavy-duty replacement bearing specifically designed for the output shaft side of XeRun and EzRun 36mm and 42mm brushless motors. Because the front bearing carries the brunt of the mechanical load from the pinion gear and drivetrain, it is often the first component to show wear. This genuine Hobbywing spare restores factory-smooth rotation and prevents efficiency-robbing shaft vibration.

Key Features:

• Broad Compatibility: A versatile "universal" front bearing for Hobbywing's most popular 1/10 and 1/8 scale motors, including the 3652, 3660, 4268, and 4274 series.
• High-Speed Rated: Engineered to withstand the extreme RPMs (up to 50,000+) generated by G2 and G3 series brushless motors without melting or seizing.
• Metal Shielded (ZZ): Features precision metal shields on both sides to keep track dust and carpet fibers out of the ball races while maintaining low rotational drag.
• Chrome Steel Construction: Manufactured using high-carbon chrome steel for maximum hardness and resistance to the "flat-spotting" that occurs under heavy jumping and landing loads.
• Precision Tolerance: Built to ABEC-standard tolerances to ensure a perfect "press-fit" into the motor's front endbell.

Installation Tip:

When replacing the front bearing, use a dedicated bearing press tool or a socket that matches the outer race of the bearing. Never press on the inner race (the center hole) when installing the bearing into the endbell, as this can "brinell" the bearing (dent the ball tracks), leading to immediate noise and premature failure. Additionally, always check the motor rotor for any signs of rubbing or damage while the motor is disassembled.
