High Tin Bimetal Oilless Bearing Aluminum Based JF-20 Corrosion Resistance

JF-20 bimetal bearing (high tin type)

Product parameters

Application features:

JF20 high-tin aluminum-based bearing is a product with a steel plate as the base and a surface rolled AISn20Cu material. The product has medium fatigue strength and load carrying capacity, good corrosion resistance, and good sliding performance.

This product is often used as a medium and small power internal combustion engine bearing bush, train engine bearing bush, air pressure shaft machine bushing, and is a novel product that replaces babbitt alloy.

Technical Parameters:

AISn20Cu Alloy layer material: AISn20Cu;

Large bearing pressure: 30N/mm2;

Higher use temperature: 150C;

Hardness of alloy layer: HB30~40.

Oilless sliding bearing refers to a special bearing

Oil-free bearings (oil-free plain bearings) are used for plain bearings. Oil-free lubricated bearings are designed for self-lubricating, oil-free bearings, smooth operation, reliable, and noise-free. Liquid lubrication conditions, separated from the lubricant does not directly contact the sliding surface, you can greatly reduce friction loss and surface wear, this film also has a certain degree of impact absorption.

But greater starting friction. The shaft portion of the bearing is called the shaft diameter portion, called the bush and the shaft diameter go together. In order to improve the friction bearing surface properties of the friction material of the inner surface layer of the casting, it is called a bearing lining.

The materials for the bearings and bearing linings are collectively referred to as bearing materials. Bearing applications typically load conditions, maintenance and lubrication or difficult operating areas at low speeds and weights.
