RAJSHREE ENTERPRISES Shaft Mounted Gear Units (SMGU) are made using high-quality international standards. These gear units help reduce speed by fitting directly onto the drive shaft, which makes installation and removal very easy. The gears are case-carburized, hardened, and finely ground, giving them strong gear teeth, better load capacity, and high torque output—all in a compact and durable design.

These SMGU units are designed to match leading global gearbox brands, making them easy to replace and known for low maintenance and simple repairs.
