The outer diameter of CSB-EPB® plastic plain bearings is not only large but also oval in the free state. First of all, the larger outer diameter of plastic bearings in the free state is a design requirement for interference press-fitting, which to ensure sufficient pretension between the plastic bearing and the housing bore after assembled, and to avoid the plastic bearing slipping out from the housing bore during working process; Secondly, that the outer diameter of the plastic bearing is oval in a free state is the inherent heat shrinkage phenomenon of plastic injection. After the plastic bearing is pressed into the H7 standard housing bore, the good elastic deformation ability of the plastic material will automatically correct its roundness to reach the design standard of value E10 or F10 or D11 tolerances. All CSB engineering plastic bearings that adopt the interference press-fitting process will be checked the tolerance of the inner hole size after pressing into the H7 standard housing bore by using a go-and-not-go-gauge.

PCB plastic clamp bearings are made of CSB-EPB3M material which is strong, durable and good in elasticity. This bearing is specially designed for the safety requirements of stamping metal sheet, especially the stamping plate of car seat. There is a diagonal cut joint on the PCB plastic clamp bearings.It is easy to assemble the PCB bearing onto the stamping metal sheet by squashing the bearing a little to pass through the mounting hole of the metal plate, then loose the bearing and the flanges at both ends can be axially limited to prevent falling off.The design of the diagonal cut joint of the PCB bearing and the good elasticity of the bearing material allow a bigger range in the tolerances of the mounting hole. It can meet the needs of customers through the automatic adaptability of plastic clamp bearings. Of course, we recommend that the tolerance deviation direction of the mounting hole and the shaft are the same, to make sure the clearance between the bearing and the shaft is in the rang of 0.02 to 0.10mm.

The selection of most standard materials for CSB-FWB® filament wound bearings is from the perspective of wear resistance design. The bearings adopt the optimized materials on completely dry friction. CRM, CRB and CRG filament wound bearings are made of hydrophobic materials so that even if immersed in water will not affect the size of the bearings. Filament wound bearings can be completely in contact with water. However, apart from CRW filament wound bearings, we do not recommend that using the bearings long-term immersion in water. Because the friction layer material of CRM, CRB and CRG filament wound bearings is designed to have optimal wear resistance under completely dry friction. CRW is a wear-resistant filament wound bearing specially developed for long-term underwater applications. The truth is the wear resistance of CRW filament wound bearings under dry friction is not as good as that in underwater applications.

CSB® plastic plain bearings can provide customized services according to customer requirements. However, we still recommend customers to choose standard specifications in the catalog. It requires 30 days for non-standard bearings...

CSB-LIN® plastic linear bearings are engineering plastic linear sliding bearings. It is composed of two parts: One is the inner liner which is made of optimized high-performance engineering plastics, and the other is the outer shell which is a magnesium-aluminum alloy with anodized hard surface treatment.About working principle. It is the sliding friction between the bearing and shaft for the plastic linear bearings and rolling friction for metal ball linear bearings. About the perspective of maintenance, plastic linear bearings can be permanently maintenance-free, while traditional metal rolling bearings it needs the help from lubricants to operate normally, because it is metal-to-metal contact among the ball, cage and the dual shaft, that is it needs frequent maintenance. About the bearing capacity, it is face-to-face contact between the engineering plastic linear bearing and the dual shaft and it is point-line contact between the metal ball linear bearing and the dual shaft, lead to the load capacity of the plastic linear bearing is greater than the metal ball linear bearing.About the linear motion performance, the sliding friction of the engineering plastic linear bearing and the rolling friction of the metal ball linear bearing make the allowed linear velocity of the former one is lower than the latter one, and the noise of the plastic linear bearing is much lower than the metal ball linear bearings. About the ability of anti-corrosion, it is very obvious: the corrosion resistance of engineering plastic linear bearings is much better than metal ball linear bearings.

Many users have always had this misunderstanding: the more expensive the CSB® plastic plain bearings, the better the performance. In fact, there are dozens of models of CSB® plastic plain bearings materials, most of which are used in special occasions. The most versatile EPB engineering plastic bearings can meet most requirements under normal working conditions with the excellent wear resistance; EPB13 and EPB7 engineering plastic bearings are designed and applied for long-term operation; EPB9 engineering plastic bearings are more expensive than EPB bearings while its wear resistance is not better, because EPB9 bearings are mainly used in anti-static applications; EPB20 engineering plastic bearings are also not cheap and the wear resistance under dry friction is generally good, however, the wear resistance is excellent when running under water at high speed; EPB24 engineering plastic bearings are specifically developed for automotive fuel systems for the high-performance; high temperature resistant EPB5 engineering plastic bearings are already widely used in 250℃ working environments, however, it is obviously not cost-effective at room temperature; Other engineering plastic bearings such as EPB14 and EPB14A are used in light-load and extremely high-speed operations.

Under standard conditions, we recommend using super-strong glue(such as Loctite 401) to bond CSB-EPB® plastic plain bearings. For plastic plain bearings materials such as EPB13 that are difficult to stick strongly to other parts, the use of two-component adhesives can achieve significantly better results(such as Loctite 406 + Primer 770). For high temperature applications, we recommend using epoxy glue(such as epoxy-based adhesives).

Why is the load capacity of CSB-LIN® plastic linear bearings larger than traditional ball linear bearings? It is easy to find out it is true from the analysis of the structure of CSB-LIN® plastic linear bearing and the traditional ball bearing. The LIN plastic linear bearing and the shaft are face-to-face contact, while the traditional ball linear bearing and the shaft surface are point and line contact. This determines that the bearing capacity of LIN plastic linear bearings is greater than traditional ball linear bearings.
