CuSn8 Chair Shaft Oilite Bronze Bushing refers to a type of bronze bushing that is specifically designed for use in chair shafts or similar applications. The CuSn8 material indicates that it is a bronze alloy containing approximately 8% tin (Sn), which provides excellent wear resistance, corrosion resistance, and mechanical properties.
Oilite bronze bushings are known for their self-lubricating properties, as they contain oil-impregnated pores that release lubricant during operation, reducing friction and wear. This makes them suitable for applications that require smooth and reliable operation over extended periods of time.
In the case of CuSn8 Chair Shaft Oilite Bronze Bushing, it is likely intended for use in chair mechanisms, such as adjustable chair bases or reclining mechanisms, where precision movement and durability are crucial. The bushing would be installed in the shaft to allow for smooth rotation and minimize friction between the moving parts.
Overall, CuSn8 Chair Shaft Oilite Bronze Bushing is a high-quality, durable, and reliable component for use in chair mechanisms and other applications where precision movement and long-term performance are essential.
Our range of Chair Shaft Bronze Bushing manufactured from CuSn8 rolled phosphor bronze alloy material is extremely versatile and well suited for a wide range of applications. These bronze bearings have been developed for slow speed, high load applications, especially suited for oscillating motion.

Chair Shaft Bronze Bushing is especially suited to severe operating conditions where frequent maintenance is not possible. Common applications are:
Chair Shaft Bronze Bushing is ideal for applications where there are high levels of contamination. Their running surface is provided with diamond-shaped lubrication pockets or a hole pattern. The lubrication pockets must be filled with grease when the bearing is installed. The Chair Shaft Bronze Bushing is produced according to the ISO 3547.
Chair Shaft Bronze Bushing are made entirely from phosphor bronze CuSn8. CuSn8 is characterized by the purity of the alloy with only a very low level of impurities. Wrapped bronze bearings are produced from strips that are subsequently wrapped and calibrated.
Whether grease or oil is used, a good quality lubricant will reduce friction and wear by separating a bronze bushing from its shaft. To protect the bushing and lubricant in highly contaminated environments, bronzegleitlager.com recommends using seals.
The main advantages of Chair Shaft Bronze Bushing include:
