Castor of sectional door in NYLON.
The main feature of this model compared to others on the market is that it consists of a bearing with a waterproof precision ball bearing. Normally, the classic models sold have bearing with stamped ball bearings that emit metallic noises when opening or closing the gate. Additionally, the play in this type of bearing allows dust to settle and increases friction on the bearing cage. Our internal bearing 6200Z is functional for up to 80,000 opening/closing cycles, which corresponds to 5 times the lifespan of standard models.
The rod is galvanized along its entire length, which prevents the assembly from oxidizing. Nylon is the most durable material for this type of product subjected to intensive use.
