DLC coating, also known as Diamond Like Carbon coating, boasts high hardness (>HV1500) and low dry friction coefficient (0.05-0.1). It is an oil-free self-lubricating coating. With a thickness up to 0.55um, it won't cause size issues. The latest technology ensures excellent lubrication and heat dissipation (dry type), extending the service life of parts by 10-50 times and boosting work efficiency by 600%, thereby reducing production costs.
