The GPM MG514T/0.8M is engineered from 40CR steel to provide a robust pinion option where load resilience and consistent tooth engagement are required. Its D-shaped bore secures the part on the motor shaft while the 5mm tooth diameter and 14 tooth profile help maintain accurate mesh under stress. Specified with a 0.8mm module and 32 pitch, this gear integrates with common motor pinions and supports reliable drivetrain operation for hobbyist tuning and repairs.
