Features | 1. Cost saving service life The heavy profiles of idler rims are carefully heat treated in depth for extra service life. 2. Maximum strength The idler roller shaft is machined by the utilization of the most modern technological advances known to the industry. Grinding and finishing methods ensure a mirror like finish and tempering with medium to low frequency heat treating equipment guarantees maximum strength. 3. Floating seal group Floating seal group of our front idler group has super seal performance under bad working conditions like being muddy or steamy etc.. it is applicable for the condition of low speed and heavy load. And it is anti-friction and can be auto-compensated after wearing. 4. Lubrication oil Lubrication oil of our frant idler assy is selected carefully. It can lubricate shaft and bushing well to lower the wearing utmostly. And it can cool the roller perfectly. Those maximize the inner structure life. |

4. Our inspectors will check the sizes when parts are being machined and parts are being assembled.
Advantages
Production Process
We use heat treatment technology and CNC fine processing production, to ensure that products are excellent quality and dimension accuracy and use blue and phos- phating surface burning to ensure good appearance, surface rust free.
High quality material
Our company buys steel from large iron and steel group steel, such as Shanghai baoshan iron and steel, Beijing shougang group, Hangzhou iron and steel. The steel has not only good mechanical properties, but also chemical stability, which ensures the high quality of our products.
Crack resistance
After heat treatment of the product, we will carry on the medium frequency induction, quenching their surface and the inner, to ensure the strength of internal and external hardness.
Quality control system
We have established a comprehensive quality control system in place to ensure that the whole process from the purchase of raw materials to final packaging are under strict quality control. Cooperating with high-tech testing instruments, such as hardness tester, spectrometer, metallographic microscope, determines the excellent quality and appearance of our products.
