AN IMPORTANT PART OF THE DOOR! WE’LL TELL YOU WHY!
DOORS ARE ALWAYS MOVING AND FLEXING
Spherical bearings reduce stress and wear on the cylinders, cylinders pins and clevises during operation
Hydraulic doors are large in size and just like an airplane wing, the doorframe flexes during operation. The hydraulic cylinders on each side of the doorway are connected to the doorframe and the building using spherical bearings. The spherical bearings accommodate the flexibility of the doorframe while at the same time allowing the cylinders to raise and lower the door without binding on the hydraulic cylinder pins and brackets. Spherical Bearings on both ends of the cylinder allow the cylinders to stay straight through the full range of motion.
