Bearing products in the wind power industry are mainly used in several parts such as spindle, gearbox and generator. The harsh used environment installation and unchanged maintenance make the quality requirements of bearing parts more stringent.GEMAN mainly provides tapered roller bearings used for gear boxes, cylindrical roller bearings and large spherical roller bearings used for generators. Our company uses all numerical control equipment grinding processing, the raceway of the ring and the rolling body is treated with superfine stone, which makes the whole contact surface high precision, and reduces the friction and the working temperature of the bearing. The internal structure of the product is optimized to improve the life of the product and increase the load capacity of the product.
