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

SF stands for three-layer composite, namely steel plate layer, copper powder layer and plastic layer. The steel plate layer plays the role of assembly positioning and bearing pressure; the copper powder layer plays the role of connecting plastic and auxiliary friction reduction; the plastic layer plays the role of wear resistance and self-lubrication. Its advantages are that it can also self-lubricate without oil, low noise during operation, thin-walled design structure with small volume, and wear resistance can be maintained for a long time without wear. It is a new type of bearing that replaces needle roller bearings, oil-containing bearings, and copper alloy bearings.

The advantages of SF series bearings are the use of high-end equipment in the production process, strong automated production capacity, small product wall thickness tolerance, high precision, advanced product formula technology, and can conduct working condition simulation tests according to customer personalized needs. Product quality and research and development technology are at the international advanced and domestic leading level.

Features

Oil-free bushing life (wear) calculation

The life of oil-free bushings depends on the amount of wear. The calculation of the amount of wear varies greatly depending on the surface pressure, sliding speed, motion form, lubrication conditions, surface roughness of the matching shaft, etc.

From the perspective that the amount of wear is proportional to the load and sliding distance, the following formula is usually used to calculate the amount of wear. Please consider it as a standard when selecting.

Estimated wear amount(mm) W=K*1×P×V×T
Wear ratio K: mm/(N/mm²·m/s·Hr)
Design surface pressure P: N/mm²
Slide speed V: m/s
Friction time T: Hr-hr
*1Approximate standard of wear ratio

Lubrication conditions	mm/ (N/mm2·m/s·Hr)	mm/ (kgf/cm2·m/min·Hr)
No lubrication	3×10-3~6×10-4	1~5×10-6

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.
