Industrial centrifugal high-speed fans, textile spinning and weaving equipment, high-speed assembly line transmission devices, high-speed centrifugal equipment, precision high-speed roller tables and wind power auxiliary transmission machinery operate under harsh conditions of ultra-high rotating speed, non-stop continuous operation, high-speed friction heat accumulation and strong centrifugal force. Ordinary cylindrical roller bearings have large structural friction resistance, low raceway finish and poor lubrication adaptability, and are prone to various high-frequency faults under high-speed operation. Continuous heat accumulation from high-speed rolling friction causes sharp temperature rise and overheating of bearings. Conventional grease is thrown off, de-oiled and delaminated under strong centrifugal force, resulting in oil shortage and dry friction on raceways. High-speed vibration causes fitting gap deviation and roller slipping, producing continuous abnormal noise, jitter and precision attenuation. Long-term high-speed fatigue operation leads to surface peeling, raceway scratching and premature fatigue failure, causing frequent equipment tripping and speed limit operation, seriously restricting the production efficiency of high-speed equipment and greatly increasing equipment operation and maintenance costs, which is the core operation and maintenance pain point of high-speed transmission equipment.

Focusing on the field of high-speed precision transmission, Japan NMT specially develops low-heat high-speed cylindrical roller bearings to solve the industry pain points of ordinary bearings such as easy heat generation, grease throwing, jitter and short fatigue life at high speed. Comprehensive upgrades are carried out in five core dimensions including low-friction structure optimization, super-finished mirror raceway processing, high-speed anti-centrifugal lubrication, dynamic gap calibration and anti-fatigue strengthened materials, greatly reducing the high-speed friction coefficient and temperature rise rate. It thoroughly eliminates lubrication failure, overheating damage and transmission instability under high-speed working conditions, realizing stable operation with high rotating speed, low temperature rise, low vibration and long service life, fully adapting to various industrial high-speed continuous operation equipment.

Core Product Advantages

1. Ultra-low friction structure suppresses heat generation: Optimized internal rolling structure and contact angle reduce invalid friction resistance. Matched with nano-level super-finished mirror raceways, it fundamentally reduces heat accumulation from high-speed friction, maintains stable temperature rise throughout operation and eliminates overheating and thermal attenuation faults.

2. High-speed anti-centrifugal lubrication prevents grease loss: Equipped with special anti-centrifugal synthetic grease for high-speed equipment with strong adhesion and resistance to high-speed centrifugal tearing. It avoids oil throwing, delamination and loss at high rotating speeds, continuously forms a uniform oil film on raceways and eliminates dry friction wear.

3. Dynamic gap calibration ensures no jitter at high speed: The internal gap is specially calibrated according to the centrifugal deformation and thermal expansion characteristics of high-speed operation to offset high-speed deformation errors, preventing roller slipping, jumping and eccentric vibration and ensuring stable and noise-free transmission at high rotating speeds.

4. Anti-fatigue strengthening adapts to continuous high-speed operation: Made of refined high-purity bearing steel with high-frequency fatigue strengthening heat treatment, it improves the material's impact resistance and fatigue resistance, avoiding surface peeling and damage during long-term 24-hour continuous high-speed operation with greatly enhanced durability.

5. Wide high-speed adaptation improves efficiency and reduces costs: Breaking the speed limit of ordinary bearings, it supports long-term high-frequency continuous high-speed operation without frequent speed limit and shutdown cooling, effectively improving equipment productivity, reducing maintenance frequency and cutting enterprise operation costs.
