High strength Oilless Trimmed flange bearings have higher toughness Oil-free lubrication maintenance-free, cost-saving, and more convenient High-quality high purity graphite filled, more stable solid lubricant Export process, precise tolerance, and higher compatibility High-temperature resistance, stable working at 300°C high-temperature High bearing capacity, corrosion resistance, wear resistance It is widely used in outdoor logistics machinery such as trucks, pusher, lifting flat wagon, port machinery, etc.

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.

Product 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.
