When it comes to high-precision machinery and equipment, having reliable and durable bearings is crucial. For applications requiring spherical bearings with exceptional accuracy and durability, sintered bronze bushings are an excellent choice. These bushings are manufactured using a sintering process that results in a uniform and dense material, ensuring optimal performance.
Sintered bronze bushings are made from a combination of copper and tin, which gives them superior strength, wear resistance, and corrosion resistance. The spherical design of these bearings allows for multi-directional movement, making them suitable for a wide range of applications.
One of the key features of sintered bronze bushings is their high accuracy. The sintering process ensures that the bushings are manufactured to precise dimensions, resulting in a tight and reliable fit. This precision is crucial for ensuring smooth and efficient operation of the machinery or equipment.
In addition to their high accuracy, sintered bronze bushings are also ISO 9001 approved. This international standard ensures that the manufacturing process meets strict quality control requirements, guaranteeing the consistency and reliability of the bushings.
The spherical design of sintered bronze bushings also makes them ideal for applications where misalignment or vibration is a concern. The ability to accommodate multi-directional movement helps to reduce wear and tear on the bearing, extending its lifespan.
Overall, sintered bronze bushings offer a combination of high accuracy, durability, and corrosion resistance that is unmatched by other bearing materials. With ISO 9001 approval, you can trust that these bushings will provide reliable performance for your critical machinery and equipment.

Self-lubricating - when in motion oil rises to the surface for lubrication and restores itself when at rest. | |||||||||
After forming, sintering and sizing, the bearings are vacuum impregnated with SAE 30 oil that provides lubricant which is metered from the bearing to the shaft during rotation. | |||||||||
Standard off-the-shelf oil impregnated bronze bearings should function satisfactorily in temperatures ranging from 10F to 220F. | |||||||||
