Bronze backing metal-polymer bearings, also known as plain bearings or self-lubricating bearings, are a type of mechanical component designed to provide smooth and reliable rotational or sliding motion while reducing friction and wear. These bearings are typically composed of a bronze backing metal that provides structural support and a polymer liner that offers self-lubricating properties.
Standard INCH SIZE bronze backing metal-polymer bearings follow a specific dimensional standard based on inches, making them suitable for a wide range of applications where imperial units are preferred. The inch-based dimensions allow for precise fitting and alignment with equipment designed according to these specifications.
The polymer liner, which is bonded to the bronze backing metal, is formulated to provide excellent wear resistance and friction-reducing properties. This eliminates the need for external lubrication, reducing maintenance requirements and downtime. The self-lubricating nature of these bearings also ensures consistent performance over a wide range of operating conditions.
Bronze backing metal-polymer bearings are commonly used in various industries, including automotive, aerospace, heavy machinery, and more. Their ability to handle high loads, resist wear, and operate with minimal lubrication requirements makes them a reliable choice for applications where smooth and reliable motion is critical.
In summary, bronze backing metal-polymer bearings with standard INCH SIZE dimensions are a type of self-lubricating plain bearing designed for applications requiring smooth and reliable motion with reduced friction and wear. Their inch-based dimensions ensure precise fitting and alignment, while their polymer liner provides excellent wear resistance and self-lubricating properties.

Structure Characteristics

 
Bronze Gleitlager Viiplus Bearing Metal-polymer self-lubricating composite materials consist of metal backing sintered porous bronze with PTFE polymer as working layer. The metal backing provides mechanical strength, while the bronze sinter layer provides a strong mechanical bonding between the backing and the bearing lining, the PTFE polymer offers exceptional low friction even under dry condition and the thermoplastic polymer is generally designed to operate with marginal lubrication. The construction promotes dimensional stability and improves the thermal conductivity. This material meets the demanding criteria for long life and trouble-free performance with or without lubrication.

· VSB-11
· Very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
· Suitable for lubricated applications
· Suitable for linear, oscillating and rotating movements
· Bronze back offers improved corrosion resistance in humid/saline environments
· Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, the transfer film created can protect the mating metal surface, suitable for rotary and oscillating movement. Very high chemical resistance, low  absorption of water and swelling, also performs very good lubrication feature, the bronze backing provides the improved corrosion resistance comparing with VSB-10.
 
 

1. PTFE/fibre mixture thickness 0.01~0.03mm, provides an excellent initial transfer film, which effectively coats the mating surfaces of the bearing assembly, forming an oxide type solid lubricant film.
2. Sintered bronze powder thickness 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE/Fibre mixture.
3. Bronze backing, provides exceptionally high load carrying capacity, excellent heat dissipation and very good corrosion resistance.
