Why is the actual size of CSB-EPB® plastic plain bearings larger than the size in the catalog?

CSB-EPB® plastic plain bearings assembly is designed for interference assembly. In the free state, the measured inner diameter of the plastic bearing is greater than the standard inner diameter value in the product catalog. After the bearing is pressed into the standard H7 seat hole, the inner diameter of the bearing will be reduced. The detection of the inner diameter of the bearing is completed under the condition of being installed in the seat hole. Measured in the non-assembled state, the outer diameter and inner diameter of the plastic bearing are larger than in the installed state, which is mainly to prevent the plastic bearing from falling off during use. If there are still differences and problems in the installation dimensions and tolerances of plastic bearings, the possible reasons are:

How to ensure long life of CSB-EPB® plastic plain bearings without lubrication?

How to ensure long life of CSB-EPB® plastic plain bearings without lubrication? Solving this problem is the core work of CSB material development engineers. Taking advantage of material modification technology to optimize basic plastics and accumulating decades of wear-resistant material modification testing data, CSB material development engineers can quickly select the correct bearing materials for various special application requirements.

How to find the appropriate CSB-EPB® plastic plain bearings material?

The most important parameters are the load, temperature, speed and PV value of the bearing in application to choose the appropriate CSB-EPB® plastic plain bearings material. Several suitable bearing materials can be selected based on these basic information. Of course, for users who use plastic bearings for the first time, can also use the 2 sets of design and application systems of engineering plastic bearings developed by CSB to carry out preliminary selection:

What are the characteristics of CSB-EPB® plastic plain bearings materials?

The reason why CSB-EPB® plastic plain bearings materials have excellent self-lubricity and wear resistance is that CSB engineers make full use of self-lubricating material modification technology. The use of high-strength fibers in high-performance engineering plastics increases the load capacity of the material, and the use of special greases reduces the friction coefficient of the material. Thereby it improves the overall wear resistance of the material and extend the service life of the bearings. High-performance engineering plastics are used as wear-resistant carriers, the reinforced fibers improve the bearing and impact resistance of the bearings, special grease reduces the friction coefficient of the bearings and create self-lubrication function.

CSB-BAL® Plastic Spherical Bearing

CSB-BAL bearings can withstand large loads. According to its different types and structures, it can bear radial load, axial load or combined load of radial and axial. Spherical bearings are generally used for low-speed swing movements(angular movements). Since the sliding surface is a spherical surface, it can also be tilted within a certain angle range (that is self-aligning movement. And it can still work normally when the support shaft and the shaft shell hole have different centers. Self-lubricating spherical bearings are mostly used in water conservancy engineering and professional machinery industries, etc.

CSB-LIN® Plastic Linear Bearing

Linear sliding bearings include linear guidance systems, roller guidance systems, optical axis and linear ball bearing guidance systems, flat cage guidance systems, linear recirculating ball or roller guidance systems and drive units(actuators and worktables). The slide rail is composed of a support rail, an optical axis and multiple sliders. The optical axis is mounted on the support rail to ensure maximum strength and rigidity throughout the operation.

CSB-EPB® plastic plain bearings

Plastic bearings can generally be divided into plastic rolling bearings and plastic sliding bearings for current applications. The working principle of plastic rolling bearings and plastic sliding bearings can be told from their name: the friction that occurs for plastic rolling bearings is rolling friction, and it is sliding friction when plastic sliding bearings work;The magnitude of rolling friction mainly depends on the manufacturing accuracy, while the magnitude of friction of plastic sliding bearings mainly depends on the material of the sliding surface.

CSB-PRB® Plastic ball bearings

Plastic ball bearing is a kind of precise mechanical component that changes the sliding friction between the shaft and the housing bore into rolling friction. It reduces the energy loss because of friction. Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling elements and cage. The inner ring is to cooperate with the shaft and rotate together with the shaft; the outer ring is to cooperate with the hosing hole as a support; the rolling element is evenly distributed by the cage between the inner ring and the outer ring, its shape, size and quantity directly affect the performance and life of the rolling bearing; the cage is to evenly distribute the rolling elements, prevent the rolling elements from falling off and guide the rolling elements to rotate to achieve rolling lubrication between shaft and housing.
