What Are Plastic Oil Rolling Bearings?
Plastic oil rolling bearings are a type of self-lubricating bearing manufactured from high-performance engineering plastics such as POM, PA, PTFE, or reinforced polymer composites. These bearings are infused with lubricating oil or solid lubricant particles, which are slowly released during operation to maintain a low-friction contact surface.
Unlike metal bearings that require frequent lubrication and are vulnerable to rust and chemical damage, plastic oil rolling bearings operate cleanly, quietly, and reliably—even in challenging environments where moisture, dust, or chemicals are present.
- Key Features of Our Plastic Oil Rolling Bearings
1. Self-Lubricating and Maintenance-Free
Our plastic oil rolling bearings contain embedded oil or solid lubricants that provide continuous lubrication throughout the bearing’s lifecycle. This eliminates the need for manual greasing, reduces downtime, and ensures consistent performance.
2. Lightweight and High Strength
Made from advanced polymer materials, these bearings are significantly lighter than steel bearings while maintaining excellent load-carrying capability. The reduced weight improves machine efficiency and supports lightweight system design.
3. Corrosion and Chemical Resistance
Plastic bearings do not rust, making them ideal for humid, corrosive, or chemically active environments. They perform exceptionally well in applications where metal bearings would deteriorate or require protective coatings.
4. Low Noise and Low Friction
The inherent damping properties of plastics reduce operational noise and vibration. Combined with oil-based lubrication, the result is exceptionally smooth, quiet motion—a key advantage in appliances, medical devices, and automation systems.
5. Wear-Resistant and Long-Lasting
Premium engineered polymers are chosen for their resistance to wear, friction heat, and mechanical stress. Even under continuous operation, the bearing maintains stable performance and long service life.
6. Non-Conductive and Non-Magnetic
Plastic oil rolling bearings are ideal for electronic equipment and environments where electrical insulation, non-magnetic properties, or EMP-safe components are required.
Types of Plastic Oil Rolling Bearings
Standard Plastic Oil Bearings
Suitable for general-purpose use, these bearings offer high performance and reliable lubrication. They are commonly found in home appliances and office machinery.
Reinforced Polymer Bearings
Designed for higher loads and demanding applications, these bearings may include glass fiber, carbon fiber, or other reinforcing agents to improve strength and thermal stability.
High-Temperature Plastic Oil Bearings
Formulated from advanced heat-resistant polymers, these bearings maintain excellent performance in elevated temperatures where standard plastics may deform.
Food-Grade Plastic Oil Bearings
Made from FDA-compliant polymers and lubricants, these bearings ensure clean, safe operation in food processing, pharmaceutical, and medical equipment.
Applications of Plastic Oil Rolling Bearings
Plastic oil rolling bearings are widely used in industries where traditional metal bearings may be inefficient, noisy, or require excessive maintenance.
Home Appliances
Used in washing machines, air purifiers, fans, blenders, and dishwashers, these bearings provide quiet operation and long-lasting performance without the need for lubrication.
Industrial Automation
Robots, conveyors, and automated machinery benefit from lightweight design, corrosion resistance, and smooth rolling action, which improve precision and reduce wear on system components.
Medical and Laboratory Equipment
Non-magnetic, noise-reducing, and clean-operation properties make plastic oil rolling bearings ideal for sensitive medical instruments and diagnostic devices.
Food Processing Industry
Corrosion-resistant and food-safe bearings ensure hygienic performance and eliminate contamination risks associated with lubricated metal bearings.
Automotive Components
Used in interior mechanisms, HVAC systems, seat adjustment mechanisms, and various non-engine components, plastic oil bearings help reduce noise and weight.
Sports and Fitness Equipment
Treadmills, exercise bikes, and rowing machines rely on smooth, quiet bearings that can withstand repeated use without maintenance.
Advantages of Choosing Our Plastic Oil Rolling Bearings
1. Superior Cost Efficiency
Low maintenance and long service life significantly reduce total ownership costs. Their self-lubricating nature eliminates the need for grease, lubricating systems, and frequent servicing.
2. Improved Environmental Sustainability
With no grease leakage or contamination risk, plastic oil rolling bearings support cleaner, environmentally friendly operations—especially important in food, medical, and green manufacturing industries.
3. High Design Flexibility
Plastic bearings can be customized with different materials, colors, shapes, and performance characteristics, allowing engineers greater freedom in product design.
4. Enhanced Reliability in Harsh Conditions
Resistant to moisture, dust, chemicals, and temperature changes, these bearings perform consistently in environments where metal bearings may corrode or seize.
5. Reduced Noise for Superior User Experience
Low-noise operation is essential in appliances, automation systems, and medical equipment. Plastic bearings naturally absorb vibration and minimize operational sound.
