High-Quality CUSN8 / CUSN6 bronze bushes To Your Specifications …

Wrapped bushing, split joint flange bushings Tin phosphor bronze,Bronze Bearings Material CuSn8P & CuSn6P, DIN 1494 / ISO 3547, Low-maintenance MADE-TO-ORDER FROM CHINA,Standard dimension of cylindrical bushes (mm sizes)From ID 10mm to 300mm. Bushings in copper alloy with graphite are available in metrical and inches dimensions.

We offer a wide range of straight and flange bronze bearings.The largest outside diameter of the products can be 305mm, the wall thickness up to 5mm, the length 200mm.

Wrapped Bronze bushings are suitable for both radial and axial movements. The bushings are well suited for

machinery in dirty environments where shock loads and/or vibrations occur.

Bronze Bearing Material

VIIPLUS Wrapped Bronze is made completely of bronze, CuSn8. The bushings are produced from strips which are then wrapped and calibrated. The working surface is machined and provided with diamond shaped with graphite indentations all over its sliding surface. These indentations serve as lubricant reservoirs, where lubricant is initially filled and progressively released during operation.

Advantages

The main advantages of wrapped bronze bearings include:

• Long service intervals
• Not affected by impurities
• Suitable for corrosive environments
• Suitable for impact loads and vibrations at low speeds
• Good heat dissipation
• Sliding Bearings always offer a solution

The bearing shell is the contact part between the sliding bearing and the journal. It is a semi-cylindrical surface in the shape of a shoe, which is very smooth. It is generally made of wear-resistant materials such as bronze and anti-friction alloys!
There are two types of bearing bushes: integral type and split type. Integral bearing bushes are usually called bushings. The integral bearing bush has two kinds of oil grooves and oil grooves. The bearing bush and the journal adopt clearance fit and generally do not rotate with the shaft.
Introduction

Features:

Graphite self-lubricating copper-bearing bushes use high-strength copper alloys (CuZn25Al5, CuZn24Al6Fe3Mn4, SAE430B, HBsC4) as basic materials, and according to the working conditions, holes are machined on the working surface and filled with solid lubricants, high-strength copper alloys Provide high load-carrying capacity, while solid lubricants create lower friction. Under dry friction conditions, we design a pre-lubricating film on the bearing surface, which can ensure that the solid lubricant is transferred to the counterpart in a short time and an effective solid lubricating film is formed.
When the sliding bearing is working, a thin oil film is required between the bearing bush and the rotating shaft to lubricate. If the lubrication is poor, there will be direct friction between the bearing bush and the rotating shaft, and the friction will generate a high temperature. Although the bearing bush is made of special high-temperature resistant alloy material, the high temperature generated by direct friction is still enough to burn it out. The bearing bush may also burn due to factors such as excessive load, high temperature, impurities in the lubricating oil, or abnormal viscosity. The sliding bearing is damaged after boiling the tile.

Bearing processing

Thick-walled bearing bushes can be cast, and in order to improve friction performance, graphite can be inlaid inside the bearing bushes to play a self-lubricating role.
The bearing material is usually soft, and the inner cylindrical surface should not be processed by grinding but can be processed by boring, diamond boring, scraping, or grinding. The grinding method should not be matched with the shaft diameter, but a special grinding rod of the same size as the bearing hole should be used. Scraping is mostly used for part of the bearing and is scraped with a wide-blade scraper. When scraping by hand, the scratches should be shallow. For bearing bushes with complex inner surface shapes, special boring methods should be used according to the specific shapes.
