Safety Bearing This unique safety device functions as both a bearing and inertia brake for motorized service doors and grilles. The safety bearing is designed to prevent the curtain from free-falling if there is damage to or failure of the motor operator, drive chain or spring assembly. If a malfunction occurs and the downward speed increases to an unsafe rate, the inertia brake absorbs the added energy and safely stops the load. |
