MXB-DU Oilless Bearing SF-1 Bushing High-Temperature Resistance

MXB-DU Oilless Bearing (also known as SF-1 bushing) is is a sliding bearing rolled with a steel plate as the base, sintered spherical bronze powder in the middle, and a mixture of polytetrafluoroethylene (PTFE) and fiber rolled on the surface.

Features:

1. The mixture of PTFE and fiber is 0.01~0.03mm, which can form a good transfer film to protect the grinding shaft and provide the self-lubricating performance of the bearing.

2. The copper powder layer is 0.20~0.30mm, which has good load-bearing capacity and wear resistance. The good thermal conductivity can promptly transfer the heat generated during the operation of the bearing. The composite material can penetrate into the gaps of the copper powder balls, improving the bonding strength.

3. Low carbon steel provides good load-bearing performance and heat transfer. Products have been widely used in the sliding parts of various machinery, such as printing machines, elevators, textile machines, tobacco machines, fitness equipment, hydraulic trucks, micromotors, solenoid valves, automobiles, motorcycles, etc.

What testing methods are used to assess the high-temperature performance and reliability of the Oilless Bearing SF-1 Bushing High-Temperature Resistance?

High-Temperature Endurance Testing: This entails subjecting the SF-1 Bushing to non-stop or cyclic high-temperature situations for an extended period to assess its performance below sustained thermal strain.

Thermal Cycling Tests: These tests simulate the temperature fluctuations that the bearing may also enjoy throughout real operation. The bushing is subjected to repeated cycles of heating and cooling to assess its potential to resist thermal shocks.

Friction and Wear Testing at Elevated Temperatures: This includes measuring the coefficient of friction and put on prices of the SF-1 Bushing under high-temperature situations.

Material Analysis: Chemical and metallurgical analyses are carried out to assess the integrity of the substances used inside the bushing after publicity to excessive temperatures.

Thermal Expansion Testing: This evaluates the dimensional balance of the Oilless Bearing SF-1 Bushing at exclusive temperatures. The coefficient of thermal enlargement is an crucial element to remember, specifically in programs with varying temperature conditions.

Lubrication Performance Tests: Assess the effectiveness of lubrication in high-temperature environments. This can also encompass comparing the overall performance of stable lubricants or unique high-temperature lubricants designed for the SF-1 Bushing.

Load and Wear Testing: High-temperature load assessments measure the bearing's ability to hold hundreds at elevated temperatures with out immoderate put on. This is crucial for applications in which the bearing is subjected to both excessive temperatures and heavy masses.

Vibration and Shock Testing: Evaluates the SF-1 Bushing's response to vibrations and shocks beneath high-temperature conditions, ensuring its balance and reliability in dynamic operating environments.
