With the iterative upgrading of automation equipment towards high speed and high efficiency, continuous high-speed operation has become the mainstream production condition. Devices such as high-speed servo motors, high-speed sorting assembly lines, high-speed cutting equipment, precision high-speed transmission modules and micro high-speed intelligent equipment have long been in harsh conditions of ultra-high rotation speed, high-frequency continuous operation and continuous friction heat generation. Limited by insufficient processing accuracy, unreasonable internal gap matching and defective lubrication systems, ordinary bearings have large friction resistance during high-speed operation, resulting in rapid heat accumulation and temperature rise in a short time.

Chain failures caused by high-speed temperature rise are the core bottleneck restricting the production capacity of high-speed equipment. Sustained temperature increase will cause lubricating grease to dilute, carbonize and drain rapidly, leading to dry friction and abnormal noise of bearings. Thermal expansion of materials tightens internal gaps, causing stuttering, locking and shutdown burnout failures. Long-term high-speed thermal circulation accelerates raceway fatigue wear, resulting in reduced equipment speed, decreased transmission accuracy and equipment jitter deviation. These problems frequently interrupt the production rhythm of high-speed production lines, and even cause motor burnout, module scrapping and high maintenance and replacement costs, seriously affecting the continuous operating efficiency of high-speed equipment.

Tailor-made for high-speed working conditions, NMT high-speed low-temperature-rise anti-locking stainless steel bearings abandon the generalized design of ordinary bearings and take "low friction, low temperature rise, high rotation speed and thermal attenuation resistance" as the core R&D standard. Adopting ultra-smooth mirror ultra-precision ground raceways, the products greatly reduce the rolling friction coefficient of steel balls and minimize friction heat generation during high-speed operation from the source. The micron-level precise internal gap ratio adapts to the thermal expansion characteristics of high speed, reserves reasonable thermal deformation space, and completely eliminates locking and jamming problems caused by thermal expansion during high-speed operation.

Equipped with a low-resistance and heat-resistant special lubrication system for high-speed equipment, the grease has strong adhesion, high temperature resistance and is not easy to carbonize and drain. It can maintain uniform oil film isolation under ultra-high-speed continuous operation, continuously reduce friction temperature rise and avoid dry friction failure. Optimized with a lightweight and high-stability cage structure, it reduces structural micro-friction and rotating resistance during high-speed operation, raises the speed limit, and realizes long-term high-speed stable operation with controllable temperature rise and non-attenuating performance. The high-quality stainless steel precision material has excellent thermal stability, is not easy to deform and fatigue under high-speed thermal cycle conditions, and maintains long-term high-speed transmission accuracy.

Overcoming the defects of ordinary bearings such as easy heat generation, easy locking and rapid speed attenuation at high speed, NMT special high-speed bearings realize low-friction temperature control, jitter-free high-speed operation and long-term failure-free performance. They perfectly adapt to various 24-hour high-speed continuous production equipment, effectively reduce the failure shutdown rate of high-speed equipment, extend the high-speed service life of bearings, cut down equipment maintenance costs, and support efficient, continuous and stable full-load operation of high-speed automatic production lines.
