M30-8CG32 Single Row Cylindrical Roller Bearing M30-8 Car Gearbox Bearing 30*80

M30-8CG32 Single Row Cylindrical Roller Bearing M30-8 Car Gearbox Bearing 30*80*22mm

The M30-8CG32 is a gear box dedicated cylindrical roller bearing, engineered for the high-load, high-speed and continuous operation demands of industrial gearboxes. Adopting precision-machined components and heavy-duty material construction, it delivers stable rotation, low friction and long service life, serving as a reliable core transmission component for various gearbox models.

• Gearbox-Optimized High Load Capacity: Optimized roller and raceway contact design, effectively bearing continuous radial loads and intermittent impact loads in gearbox operation, matching the transmission characteristics of industrial gearboxes.
• Precision Machining for Low Noise: Strict dimensional tolerance control and smooth raceway surface finish, reducing rotational friction and vibration, realizing low-noise operation of gearbox transmission systems.
• Durable for Long-Term Operation: Forged from high-carbon chromium bearing steel with professional heat treatment, featuring high hardness, excellent wear and fatigue resistance, adapting to the long-term continuous working conditions of gearboxes.

• Industrial Gearboxes: Helical gear reducers, planetary gearboxes, cylindrical gearboxes for general machinery
• Mechanical Transmission: Conveyor equipment gearboxes, textile machinery gearboxes, printing machinery gearboxes
• Light & Medium Engineering Machinery: Small construction machinery, agricultural machinery gearbox systems
• Aftermarket: Direct OEM replacement bearing for gearbox maintenance and refitting, ensuring perfect compatibility

• Gearbox Specialized Design: Tailored for gearbox working conditions, the structural and performance parameters are perfectly matched with mainstream gearbox models.
• OEM Standard Compliance: Strictly manufactured according to industrial bearing standards, consistent with original equipment dimensions and precision, supporting direct plug-and-play replacement.
• Comprehensive Quality Control: Full-process inspection from raw material selection to finished product delivery, ensuring stable precision and performance of each bearing.
• Customizable Adaptability: Supports small adjustments of precision grade and lubrication mode to adapt to different working conditions of gearboxes (high temperature, dust, etc.).
