PRODUCT CHARACTERISTICS
CHWM ® Engineering plastic bearings use high-performance engineering plastics as the base material, and improve their comprehensive wear resistance by implanting high-strength fibers and special solid lubricating grease inside through polymer material modification technology; The high-strength fiber mesh structure enhances the strength of the material, and the composite of special solid lubricating grease makes CHWM ® Engineering plastic bearings have excellent self-lubricating and wear-resistant properties. Whether it is the automotive industry with high durability requirements, high-speed applications, underwater applications, high-temperature and corrosion-resistant applications, or the food industry that requires compliance with FDA standards, CHWM provides different solutions for global industries.
CHWM ® Plastic bearings are made of modern engineering plastic compounds, which consist of basic engineering plastics, reinforcing fibers, and solid lubricating components. The structure is uniform, and theoretically, the entire wall thickness can be used as a wear zone. This helps to reduce CHWM ® The friction coefficient of sliding bearings is improved, and the overall wear resistance of the material is enhanced, which can effectively protect the metal shaft that is matched with it. The uniform material, which does not contain any oil or grease but has solid lubricating components and fiber-reinforced materials, ensures complete self lubrication using its own lubricating components in any form of motion. The friction coefficient and wear coefficient of bearing products are very low throughout their entire lifecycle, ensuring a long service life.
Due to its large load-bearing surface and good elastic deformation performance of plastic, CHWM ® Sliding bearings can also withstand heavy impact and edge loads. The reinforcing fibers further enhance the mechanical properties. Combining CHWM ® The material properties of sliding bearings allow for the use of "soft" shafts in many applications. Even with edge loads, the risk of shaft wear is significantly lower than that of needle roller bearings. Plastic bearings have always had technological and cost advantages over metal sliding bearings, making them a good alternative. They improve performance by precisely adding reinforcing materials and solid lubricants, suitable for various applications and requirements, reducing maintenance work and achieving technological improvements.

INFORMATION AND CHART
|
Left: steep side angle, standard geometric shape Right: flat side angle |
Optimized spiral angle for higher efficiency Smooth thread angle, CHWM high helix screw (similar to trapezoidal thread), can more effectively convert rotational torque into translational motion. Compared to steeper helix angles, this means lower power loss. |
|
Left: angular tooth flank, standard geometric shape Right: circular tooth flank, CHWM geometric shape |
Circular tooth shape achieves quiet and vibration reducing operation The design of circular teeth reduces the surface contact between the screw nut and the screw. Therefore, the CHWM screw nut operates without vibration and is almost silent. This is because the larger the contact surface between the two surfaces, the more vibration is transmitted, resulting in creaking or squeaking sounds. Circular teeth minimize this effect to the greatest extent possible, and the threads can move without lubrication. |
|
Left: Symmetric standard geometric shape Right: Asymmetric CHWM geometric shape |
Asymmetric design extends service life Due to the large distance between each CHWM thread, the threads perfectly match the characteristics of lubrication free CHWM high-performance engineering plastics. For all sizes, the proportion of friction optimized engineering plastics in the thread can be increased by 1.3 times. The service life is five times longer than standard geometric shapes, and more wear-resistant materials and higher efficiency levels are crucial. The larger the diameter of the screw, the stronger its impact force. The use of CHWM zero backlash threaded nuts with integrated spring preloading can minimize clearance throughout the entire lifecycle. |
