Packaging & Shipping
Packing
1. Primary Protection
- Individual Wrapping: Use anti-rust paper or plastic wrapping to protect the bearings from moisture and dust.
- Lubricant Preservation: For self-lubricating bearings, ensure a protective coating or vacuum-sealed packaging to prevent lubricant loss or contamination.
2. Grouping and Layering
- Small Bearings: Pack in small boxes with separators to avoid scratches or deformation.
- Large Bearings: Use foam inserts or molded protective material for secure placement.
- Avoid Overcrowding: Allow space between items to prevent surface damage.
3. Outer Packaging
- Boxes: Use sturdy cardboard or wooden crates, depending on the weight and size.
- Reinforcement: Add edge protectors or internal bracing for stability during transport.
- Sealing: Secure with heavy-duty tape or metal straps for larger crates.
4. Moisture and Corrosion Protection
- Desiccants: Include silica gel or other moisture-absorbing agents inside packaging.
- Rust Prevention: Apply anti-corrosion coatings if bearings are exposed to humid environments.
5. Labeling
- Clear Identification: Include product details, batch numbers, handling instructions, and orientation labels (e.g., "This Side Up").
- Fragile Marking: If applicable, label packages as fragile.
Delivery
1. Transport Mode Selection
- Air Freight: Suitable for urgent and lightweight shipments.
- Sea Freight: Cost-effective for bulk orders, though slower.
- Land Freight: Use for regional deliveries.
2. Shock and Vibration Protection

The applications
Civil Engineering Machinery Applications
Self - lubricating bearings with impact and dust resistance are ideal for civil engineering machinery. They solve lubrication issues, cut running noise, and extend bearing lifespan, especially in harsh mining and outdoor settings. Widely used in excavators' lift arms, undercarriage wheels, and hydraulic cylinders.
Application of new energy equipment
Featuring weather resistance, high load capacity, and self - lubricating maintenance - free properties, these bearings showcase their superiority in challenging refueling scenarios like outdoors, high altitudes, and underwater. General rolling bearings are restricted when exposed to the outdoors without timely maintenance, but self - lubricating bearings can effectively address such issues. They are, for instance, applied in wind and solar power stations.
Self - lubricating bearings, with their lightweight design, low - noise operation, and oil - free characteristics, have been rapidly promoted for automotive applications. They are constantly replacing needle roller and powder bearings, giving rise to new applications. These bearings not only support parts on the shaft but also prevent shaft deviation or jamming within the movable range. Additionally, they reduce friction and damage to parts during operation.

FAQ
-
What exactly are self-lubricating bearings and how do they function?
Self-lubricating bearings, which are also referred to as plain bearings or bushings, are engineered to operate without the necessity of external lubrication. They have solid lubricants incorporated within their structure. During operation, as the bearing moves, the friction creates a thin film of lubricant, which helps in reducing wear and prolonging the lifespan of the bearing.
-
