China best China Best Radial Spherical Plain Bearing double row ball bearing

Product Description

I. Product Description

1. Spherical plain bearings have an inner ring with a spheral convex outside surface and an outer ring with a correspondingly spheral outer concave inside surface. The design makes them particularly suitable for bearing arrangements where alignment movements between shaft and housing have to be accommodated, or where oscillating or recurrent tilting or slewing movements must be permitted or relatively slow sliding speeds.  
    Design and application features:
2. Outer ring is carbon chromium steel, fractured, hardened and phosphated. Sliding surface is treated with MoS2. Inner ring is carbon chromium steel, hardened and phosphated. Sliding surface is treated with MoS2. It has characteristics of wear-resistance, wear-corrosion and self-aligning, suitable for heavy radial load and any direction lower axial load. GE…ES series can be lubricated via annular grooves and lubrication holes in both rings. GE…ES-2RS series have 2 seals on both sides, for bearing arrangements where separate seals do not provide adequate protection.

Challenges of Lubricant Contamination in Sliding Bearings and Solutions

Lubricant contamination in sliding bearings can lead to various challenges that impact performance and longevity. Here are some challenges and solutions:

Challenge: Reduced Lubrication Effectiveness

Contaminants such as dust, dirt, moisture, and foreign particles can compromise the lubricant’s ability to provide effective lubrication between bearing surfaces.

Solution: Regular maintenance practices involving cleaning and relubrication help remove contaminants and restore the lubricant’s effectiveness. Proper seals and shields can also prevent contaminants from entering the bearing.

Challenge: Increased Friction and Wear

Contaminants in the lubricant can create abrasive particles that increase friction and accelerate wear on bearing surfaces.

Solution: Using high-quality, clean lubricants and implementing effective filtration systems can minimize the presence of contaminants, reducing friction and wear.

Challenge: Component Damage

Contaminants can cause pitting, scratching, and other damage to bearing surfaces, leading to decreased performance and potential bearing failure.

Solution: Regular inspections and cleaning routines are essential to prevent the accumulation of contaminants. Using lubricants with appropriate viscosity and additives can also help protect bearing surfaces.

Challenge: Increased Heat and Temperature

Contaminants can create heat and increase operating temperatures due to increased friction, which can negatively impact bearing performance.

Solution: Clean lubricants with proper viscosity and thermal stability are essential to dissipate heat effectively. Maintaining proper lubrication levels helps manage temperature rise.

Challenge: Corrosion

Moisture and certain contaminants can lead to corrosion of bearing surfaces, which compromises their structural integrity.

Solution: Proper storage and handling of bearings, as well as using corrosion-resistant lubricants, can mitigate the risk of corrosion. Seals and shields also provide additional protection against moisture ingress.

Challenge: Lubricant Breakdown

Contaminants and high operating temperatures can cause lubricants to degrade over time, reducing their lubricating properties.

Solution: Monitoring lubricant condition and replenishing or changing it at appropriate intervals helps maintain its effectiveness. Using lubricants with good oxidation resistance is also important.

Lubricant contamination in sliding bearings can significantly impact their performance and longevity. Implementing proper maintenance practices, using clean and suitable lubricants, and employing effective sealing mechanisms are key strategies to address these challenges and ensure optimal sliding bearing operation.

Impact of Materials on Sliding Bearing Performance and Durability

The choice of materials used in sliding bearings significantly influences their performance, longevity, and suitability for specific applications. Different materials offer varying characteristics that affect factors such as friction, wear resistance, load capacity, and corrosion resistance. Here are some common materials and their effects:

  • Bronze Bearings: Bronze bearings, often made from bronze alloys, offer good load-carrying capacity and resistance to wear. They are suitable for applications with moderate to heavy loads and low to moderate speeds. Bronze bearings also have good heat dissipation properties.
  • Steel Bearings: Steel bearings, particularly those made from stainless steel, provide excellent corrosion resistance and are suitable for applications exposed to harsh environments or moisture. Steel bearings are often used in marine and food processing industries.
  • Polymer Bearings: Polymer bearings, such as those made from materials like PTFE (polytetrafluoroethylene) or nylon, offer low friction and self-lubricating properties. They are suitable for applications where minimizing friction and wear is critical.
  • Composite Bearings: Composite bearings combine different materials to achieve specific performance characteristics. For instance, they might feature a polymer matrix with embedded reinforcing fibers for improved load capacity and wear resistance.
  • Graphite Bearings: Bearings with graphite as a lubricating element can operate without additional lubrication in certain conditions, reducing maintenance needs and offering self-lubricating properties.

The selection of materials should consider factors such as the application’s operating conditions, load requirements, speed, temperature, and the presence of corrosive substances. The right material choice ensures optimal performance, durability, and minimal maintenance for sliding bearings.
