Precision Wound Armature

Automated CNC winding ensures uniform wire tension and consistent impedance across all units. Reduces vibration and extends service life.

Class F Insulation

High-grade polyimide insulation rated to 155°C. Resists thermal degradation during heavy-duty continuous operation.

OEM Dimensional Accuracy

Shaft tolerances held to ±0.01mm. Drop-in replacement — no modification required for listed tool models.

100% Pre-Shipment Testing

Every motor passes no-load run, current draw, vibration, and insulation resistance tests before packing. Rejection rate < 0.2%.

Is this motor a direct drop-in replacement for the Bosch GWS 7-115?

Yes. The RDG-MTR-18V-001 is dimensionally identical to the OEM Bosch GWS 7-115 motor. Shaft diameter, mounting flange, and electrical connections match the original specification. No modification is required.

What is the warranty on this product?

RIDGE provides a 12-month warranty against manufacturing defects for all motors. Warranty covers electrical failure under normal operating conditions. Damage from incorrect installation or overvoltage is excluded.
