The rotation speed of the spindle of the soybean milk machine reaches 15000 rpm during operation. Such high-speed rotary motion has very high requirements on the spindle bearings. However, only powder metallurgy oiled bearings of traditional...

CSB Company is a professional manufacturer of sliding bearings. In order to develop non-metallic polymer sliding bearing products more professionally, CSB Company set up a new company named Jiashan CSB Plastic Bearing Technology Co., Ltd. in April 2009, which integrates the development, production and sales of the non-metallic self-lubricating materials and non-metallic sliding bearings.

Engineering plastic bearings are applied in bottle washing machines of pharmaceutical machinery and play a very critical role which is an important part of the washing, filling and sealing interlocking machine group. The quality of the bottle washer...

On September 28th, 2008, the National Sliding Bearing Standardization Technical Committee Self-lubricating Bearing Sub-Technical Committee was established. CSB Company is the secretariat and its office is located in CSB.

The wear resistance of the plastic sliding bearing mainly depends on the wear resistance of the plastic sliding bearing material itself. However, the abradability of the plastic sliding bearing is also closely related to the following factors: the material, hardness and roughness of the grinding shaft, the speed and load of the bearing, the ambient temperature and humidity of the work environment, etc…. As a manufacturer of plastic sliding bearings, CSB is constantly optimizing the wear resistance of plastic bearing materials and providing users with the correct selection guidance. As a user, it is important to follow the instructions for the selection and assembly of plastic sliding bearings showing in the product manual provided by the plastic sliding bearing manufacturers.

Bearings can be divided into rolling bearings and sliding bearings. Rolling friction occurs when the rolling bearing works, and sliding friction between the surfaces occurs when the sliding bearing works. These are two different ways of movement. Currently, the materials and manufacturing technologies of rolling bearings both domestic and abroad are already very mature. However, the materials and manufacturing technologies of sliding bearings are gradually being reformed and developed with the continuous improvement of design and service requirements.

Bearings can be divided into rolling bearings and sliding bearings from the working principle. The rolling friction pair is formed when the rolling bearing works and the sliding friction pair is formed when the sliding bearing works. This determines that the friction coefficients of rolling bearings and sliding bearings differ by at least 10 orders of magnitude. Under a certain load and speed without lubrication, the size of the friction coefficient of the rolling bearing basically depends on the manufacturing accuracy of the balls, the inner and outer rings of the bearing, and the mutual clearance between them. The friction of rolling bearings is not directly related to the bearing material itself. Rolling bearings generally require regular lubricants. Under the same load and speed without lubrication, the friction coefficient of the sliding bearing mainly depends on the self-lubricating performance of the bearing material itself. The sliding bearing material itself has good self-lubricating properties and can work for a long time without or with little oil. The sliding bearing takes advantages of the self-lubricating technology, achieves self-lubricating and maintenance-free feature for bearings. So that more and more engineering designers adopt the sliding bearings.

Recently, CSB has successfully developed the Oil-free sliding bearing CRB after 7 years of R&D work and tests. This bearing is processed by filament wound. Its load-bearing capacity, wear resistance performance and corrosion resistance are...
