Manufactured under strict quality controls, this deep groove ball bearing features an inside diameter of 56mm, an outside diameter of 70mm, and a width of 49mm. The advanced polycarbonate material provides superior chemical resistance, non-conductivity, and a significant weight advantage over traditional steel bearings. This makes it an excellent choice for applications where exposure to corrosive substances or the need for electrical insulation is critical, and for reducing overall system mass in power transmission assemblies.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure bearing and mating shaft/housing surfaces are clean and free of debris. 2. Apply a light coating of appropriate lubricant to the shaft and the inner bore of the bearing. 3. Carefully press or slide the bearing onto the shaft, ensuring it seats fully and squarely. Avoid excessive force that could damage the polycarbonate structure.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Applying excessive force during installation, leading to cracking or deformation of the polycarbonate. | Use a controlled press fit or a bearing installation tool. Ensure the shaft and housing are within specified tolerances and consider slight warming of the bearing bore or cooling of the shaft for easier assembly. |
| Using incompatible lubricants or cleaning agents that degrade polycarbonate. | Consult the material data sheet for recommended lubricants and cleaning solvents. Avoid aggressive chemicals, ketones, and chlorinated solvents which can attack polycarbonate. |
