NNC 4840 CV
Double Row Full Complement Cylindrical Roller Bearings feature a double-row, full complement roller design, allowing more rollers than standard bearings without a cage, which significantly enhances radial load capacity and rigidity. These bearings maintain stable operation under heavy loads while accommodating slight shaft deflection or misalignment, making them ideal for machinery subject to high radial and impact loads.
JRZC Double Row Full Complement Cylindrical Roller Bearings advantages:
Manufactured with high-purity bearing steel and optimized roller profiles for superior load capacity and extended fatigue life.
Cage-free full-complement design reduces friction, maximizes space utilization, and supports high-density load requirements.
Precision heat treatment and strict dimensional control ensure low vibration, low noise, and low operating temperature.
Offers customizable internal clearance and surface treatment options, adaptable to diverse operating conditions.
This series is widely used in gearboxes, heavy-duty motors, metallurgical equipment, mining machinery, and other high-load industrial applications, delivering reliable and long-lasting performance.

Our Double Row Full Complement Cylindrical Roller Bearings deliver clear advantages in heavy-duty and high-load applications. The full complement design maximizes the number of rollers, providing exceptionally high radial load capacity and enhanced rigidity, ideal for machinery under constant or impact loads. The cage-free structure reduces friction and heat generation, improving efficiency and extending service life.
These bearings can accommodate slight shaft deflection or misalignment, ensuring stable and reliable operation even under demanding conditions. With customizable internal clearances and surface treatments, they are perfectly suited for gearboxes, heavy-duty motors, metallurgical equipment, mining machinery, and other industrial systems where durability, performance, and low maintenance are critical.
FAQ
Q1: What is a double row full complement cylindrical roller bearing?
A: It is a cylindrical roller bearing with two rows of rollers and no cage, allowing more rollers in the same space, which significantly increases radial load capacity and rigidity.
Q2: What are the main advantages of full complement bearings?
A: Full complement bearings maximize the number of rollers, providing higher load capacity, improved rigidity, and better resistance to deformation under heavy loads.
Q3: Can these bearings support axial loads?
A: Double row full complement cylindrical roller bearings are primarily designed for radial loads. Axial load capacity is very limited and typically requires a separate locating bearing.
Q4: What applications are suitable for these bearings?
A: They are ideal for gearboxes, heavy-duty motors, metallurgical equipment, mining machinery, rolling mills, and other high-load industrial applications.
