Product Description

Key Features of PP Plastic Double Row Deep Groove Ball Bearing

(Custom configurations available upon request.)

Material Composition:

Outer and Inner Rings: Made from PP (Polypropylene), providing lightweight and durable performance.
Balls: Typically steel, ceramic, or polymer, depending on the specific application requirements.
Cage: PP or other compatible polymer for low friction and smooth operation.
Lightweight Design:

Polypropylene construction significantly reduces weight, ideal for applications where minimizing mass is critical.
Corrosion Resistance:

Excellent resistance to water, chemicals, and environmental exposure, making it suitable for use in corrosive or moist environments.
Non-Magnetic Properties:

Non-metallic materials eliminate magnetic interference, useful in sensitive electronic and medical applications.
Self-Lubricating:

PP bearings have low friction properties, reducing or eliminating the need for external lubrication.
High Wear Resistance:

Durable polymer material ensures resistance to wear and abrasion, extending bearing life in various applications.
Temperature Resistance:

Operates efficiently within a moderate temperature range, typically between -30°C to +100°C (-22°F to +212°F).
Smooth Operation:

Double-row design provides higher load-carrying capacity and stability compared to single-row bearings.
Noise Reduction:

The plastic material reduces vibration and noise, making it ideal for applications requiring quiet operation.
