The standard sphere is made of highly wear-resistant EPB15 material. It has a higher load and a very low coefficient of friction during dry running. It is especially suitable for high-load and low-speed motion. CSB can also adopt other standard wear-resistant materials to make spheres, thereby improving the special performance of joint bearings.
The standard base is made of high-strength M163 material, which is a fiber-reinforced polymer material with good impact resistance. The operating temperature is -30 ° C to + 80 ° C. CSB can also use other materials to make the base, such as magnesium aluminum alloy and stainless steel, please 真人博狗.
Load and temperature
Under normal external temperature conditions, plastic spherical plain bearings have a higher load-bearing capacity, although their weight is only 1/5 of that of metal spherical plain bearings; plastic spherical plain bearings have a certain shock absorption because the ball and base are made of special plastic performance. When plastic spherical bearings are used for a long time under high load or extreme temperature, we recommend that they be tested through actual experiments.
Coefficient of friction and speed
The CSB-BAL® plastic articulated bearing has a shaft sliding in the sphere during normal use, and there is a certain amount of sliding when the angle is adjusted between the sphere and the base; the ball material is made of EPB15 with a very low coefficient of friction, and when the load is low A high speed of movement can be achieved between the shaft and the sphere.Chemical resistance and water absorption
CSB-BAL® standard plastic spherical plain bearings are made entirely of polymers and are resistant to weak acids and bases, as well as fuels and various lubricants. Water absorption is related to materials. Under standard atmospheric pressure, the water absorption of plastic spherical plain bearings is 1.3%, and the saturated water absorption of immersion water is 6.5%. If you need a lower water absorption plastic articulated bearing, please 真人博狗.Anti-radiation and UV performance
CSB-BAL® standard plastic joints can be used outdoors and have good corrosion resistance. Standard plastic spherical plain bearings are permanently resistant to UV rays. Under ultraviolet radiation, the color of the sphere will change slightly but it will not affect its mechanical properties, conductive properties and thermal properties.Tolerance and inspection
CSB-BAL standard plastic joint ball inner diameter tolerance adopts E10 standard, shaft tolerance is between h6 to h9. The inside diameter test uses the plug gauge test instead of the vernier caliper test. If you need bearings with higher accuracy or other tolerances, please 真人博狗.
