Oilless Trimmed flange bearings

Oilless Trimmed flange bearings

Self-lubricating bronze bearings are engineered for applications where external lubrication is impractical. Solid lubricants are compressed and molded directly into the bearing to guarantee a maintenance-free product. No additional lubrication is necessary.

Oilless Trimmed flange bearings

High-strength oil-less trimmed flange bearings offer enhanced toughness and maintenance-free, cost-effective oil-free lubrication. They feature high-purity graphite fillings that provide stable solid lubrication. With precise export tolerances and high compatibility, these bearings withstand temperatures up to 300°C and boast excellent bearing capacity, corrosion resistance, and wear resistance. They are widely used in outdoor logistics machinery such as trucks, pushers, lifting flat wagons, and port equipment.

Oilless Trimmed flange bearings with solid lubricant

Product Overview

1. Low maintenance frequency.
2. It can bear heavier load than a rolling bearing.
3. It can also be used under severe temperature conditions of “high temperature” and “low temperature”.
4. Compared with rolling bearings, the bushing is thinner and saves space.
5. It can be used for linear motion and rotary motion.

Oilless Trimmed Flange Bearings Feature

1. Composite products based on high strength brass and inlaid with solid lubricant.
2. It is most suitable for use under conditions of heavy load and low speed operation.
3. Excellent wear resistance can be exerted at parts with reciprocating motion, frequent starting and stopping, etc., where oil film is difficult to form.

  • Inner diameter precision class 7 ensures more accurate locating
  • which implements quality inspection before leaving the factory to provide users with products that meet the specifications of the catalog

What Materials Are Viiplus Oilless Bushings Made Of, And What Features Do They Have Respectively?

  • VIIPLUS provides oilless bushings, including copper alloy, bronze casting, and dry type.
  • Copper alloys (metals) have high-temperature resistance, excellent chemical resistance, and impact resistance, and are suitable for heavy load and low-speed operation.
  • Bronze castings (metals) have excellent sintering resistance, can realize micro-operation, and are suitable for low-load and high-speed operation.
  • Dry (composite layers), resistant to high temperature, suitable for heavy load and low-speed operation, thin wall, and compact.
