Why Choose This Replacement Armature
OE-Spec Compatibility
This armature is manufactured to match the original equipment specifications of the Bosch GW20-2 exactly. Every dimension — from shaft diameter to commutator/lamination stack length — is verified for drop-in fit. No modifications or adapters needed.
Premium Copper Windings
We use only high-grade copper wire for windings, ensuring maximum electrical conductivity and minimal heat generation. Unlike lower-quality alternatives, our copper windings maintain consistent performance across prolonged use cycles.
High-Temperature Insulation
Each armature features advanced insulation materials rated for high-temperature operation. This prevents shorts, winding failures, and premature burnout — especially critical for demolition hammers used in continuous-duty applications.
Precision Balancing
Every armature undergoes dynamic balancing to minimize vibration during operation. Reduced vibration means less wear on bearings, longer brush life, and smoother tool operation.
Quality Assurance
At Prime Armature, every armature is tested before shipping:
- ✓ Surge testing for winding integrity
