SJS® - Super Joint System
SJS® Super Joint System is a mechanical clutch system that helps prevent motor and gear damage in grinders if the wheel is forced to a stop. The drive shaft from the armature to the drive gear is spring-loaded during normal grinding load. If binding occurs or the wheel is forced to stop, the spring is compressed allowing the drive shaft to slip. The gear tension is minimized while the armature continues to rotate, which helps prevent motor burn-out. SJS® is a mechanical clutch system, not elecronic, so the grinder does not require a re-start if the wheel binds.[Learn More]

About Model

Makita 5”sj™角磨机结合10.5安培power with comfort and motor-protection features for longer-lasting industrial performance. The GA5020 is engineered with Makita’s innovative - SJS™ technology is a mechanical clutch system that helps prevent motor and gear damage

10.5 AMP Power with SJS™ to Protect Gears

The GA5020 is powered by a 10.5 AMP motor that delivers 11,000 RPM, with electric brake for maximum productivity. Labyrinth construction protects the motor with a complex set of channels, prohibiting dust and contamination. In addition, the protective zig-zag varnish seals the motor and bearings from dust and debris by creating a barrier under rotation. The GA5020 is engineered with SJS™, an innovation from Makita that protects the gears by automatically disengaging the motor should the grinding wheel accidentally catch or bind.

The GA5020 weighs only 5.9 lbs. and is built with comfort and ergonomic features for extended use, including an ergonomic rubberized rear handle with trigger switch. In addition, the side handle can be easily installed on either side of the tool. It is a versatile and powerful grinder engineered for demanding applications including cutting, ferrous metal, paint and rust removal, shipyard maintenance, heavy machinery, metal polishing, general steel grinding, auto repair work, cutting brick and masonry, and restoration work. The grinder is built for welders, fabricators, plumbers, masons, electricians, automotive technicians, stone and tile workers, HVAC, and general contractors.
