CSB-FWB® Filament-wound bearings

Product properties

● The backing material of CSB-FWB ® material is high strength glass fiber with epoxy resin and the lubricating layer of it is PTFE wound fiber or special lubricating fiber. Therefore, this special structure performs an outstanding anti-wear feature and low friction coefficient under high load and low speed condition. Furthermore, this absolutely new idea gives better solution for high load and excellent wear resistance possibility.
● Very high load capacity,  Max.140Mpa
● Very good chemical resistance;
● Lower friction and good wear properties. Friction coefficient<0.12
● Long time dry operation without oil

Friction coefficient

Friction Coefficient of filament Bearing is 0.03~0.12. The main factors affect the Friction Coefficient are Load, Moving method, Speed and Roughness of mating surfaces. Graph 1 shows the friction coefficient is going down while load is increasing under the rotation method.


Specification: CRB-6070-50 

Shaft: 45# HRC50, Ra=0.4 

Load: 20~140MPa 

Speed: 1.0m/min 

Lubricate: Dry

The anti-wear property

The main factors affect the anti-wear property are the load, moving method, speed and roughness of mating surfaces. Graph 2 shows the bearing wear off under room temperature with the load of 50MPa when the bearing is swinging. It is found the wear off increases sharply during the initial running-in while the lubricant is transferred from the inner liner and a smooth surface is created there of to form  the lubricating  surface. After running-in period, it will maintain stable without wear off.


Specification: CRB-4050-30 

Shaft: 45# HRC50, Ra=0.4 

Load: 50MPa

Speed: 1.0m/min, ±45°

Lubrication: Dry

CSB-FWB® installation method

FWB纤维缠绕轴承安装方式

CSB-FWB® Filament Wound Bearings Finder[V2.0] is based on the analysis and calculation of a large number of test data in CSB laboratory. You can calculations material data by entering parameters such as bearing load, speed, and temperature, and finally output material adaptation data.
Because the system calculate and analyze based on lab data, it can't exactly meet the ractual use requirements absolutly. The system data verification has certain limitations; CSB recommends that the bearing must be tested again to verify whether it meets the actual use requirements.
CSB-FWB® Filament Wound Bearings Finder output data information is only for design reference, and can not be used as the final standard for determining the bearing material conformity, If you have any questions, please contact CSB sales engineers.

CSB® Bearing Material Chemical Resistance

Please select bearing material and medium...

CSB® bearing material chemical resistance data is a comparison test result of the CSB chemistry laboratory using laboratory specimens or similar chemicals at room temperature 23 ℃, without considering the impact of other temperatures and chemical medium mixtures on the chemical resistance of CSB® bearing materials ; Therefore, this data can only act as a reference. CSB® recommends that the chemical resistance of actual parts should be tested under application conditions and verify the suitability of the bearings.
