HRCSG1822 - 22t 48p Hardened Steel Pinion 1/8 Gear Bore

This product is a hardened steel 22-tooth 48-pitch pinion gear designed for RC vehicles using motors with a 1/8 inch (3.175 mm) shaft. The precision CNC-machined steel gear provides a durable drivetrain connection between the motor and spur gear while reducing wear under high-power brushless systems. Case-hardened construction improves resistance to tooth wear and helps maintain consistent gear mesh during extended use. A heavy-duty set screw secures the pinion to the motor shaft, ensuring reliable power transfer and stable gear alignment during acceleration and braking.

• 22 tooth gear size with 48 pitch designed for common 1/10 scale drivetrain setups.
• Hardened 4140 steel construction improves durability and wear resistance.
• Precision CNC-machined gear teeth for smooth engagement with 48P spur gears.
• Case-hardened surface increases gear life under high load and brushless power.
• 1/8 inch (3.175 mm) bore fits most standard RC motor shafts.
• Heavy-duty 4 mm set screw helps keep the gear securely attached to the shaft.
• Lightweight precision design helps reduce rotating mass and improve drivetrain efficiency.
