NTN Cylindrical Roller Bearings: Elevating Industrial Performance with Precision and Reliability
August 9, 2024
Discover the quality and performance of NTN cylindrical roller bearings, designed to enhance industrial performance and reliability with Global Bearings.
NTN Cylindrical Roller Bearings stand at the forefront of industrial innovation, offering unparalleled precision and reliability for a wide range of applications. These meticulously engineered components are designed to handle heavy radial loads and moderate axial loads, making them indispensable in Australia’s demanding industrial landscape.
Their unique design, featuring cylindrical rollers that provide line contact with the raceways, ensures uniform load distribution and minimal friction, setting a new standard for efficiency in industrial operations.
Features of NTN Cylindrical Roller Bearings
High Load Capacity: NTN cylindrical roller bearings are designed to accommodate heavy radial loads due to the line contact formed between their rolling elements and raceways. This feature makes them suitable for applications that require high load-bearing capabilities.
High-Speed Performance: These bearings are available in high-speed versions, allowing them to operate at higher rotational speeds without compromising their performance. This is achieved through the use of optimised internal specifications and advanced cage materials.
Thermal Expansion Management: The inner and outer rings of NTN cylindrical roller bearings can move freely in the axial direction, making them ideal for applications that experience thermal expansion of the shaft, such as electric motors.
Special Heat Treatments: NTN employs advanced heat treatments like the Austenite Strengthening (AS) process and High Lubrication (HL) surface treatment to enhance bearing life and performance. The AS process creates a thin layer of retained austenite that increases bearing life, while the HL surface treatment improves oil film formation in bearing contact areas.
High-Capacity Separators: NTN has developed technology that combines the high load capacity of full complement bearings with the high rotational speed capabilities of caged designs. This is achieved by using resin rolling element separators, which reduce friction and heat generation.
Benefits of NTN Cylindrical Roller Bearings
• Enhanced Reliability: The advanced heat treatments and optimised designs of NTN cylindrical roller bearings ensure high reliability, reducing the risk of bearing failure and downtime.
• Improved Performance: These bearings are designed to operate efficiently, with reduced friction and heat generation, which translates to improved performance and longer service life.
• Customisation Options: NTN offers a wide range of standard and tailor-made cylindrical roller bearings to meet specific application needs, ensuring that the right bearing is selected for each use case.
• Global Availability: NTN has a global presence with manufacturing plants and distribution centres throughout the Americas, ensuring that their bearings are readily available and can be quickly shipped to customers worldwide.
Applications of NTN Cylindrical Roller Bearings
Industrial Applications
NTN cylindrical roller bearings are used in a wide range of industrial applications, including reduction gears for robots, gear motors for fixed machinery, gearboxes for mobile equipment, and speed multipliers for wind turbines.
High-Radial Load Applications
These bearings are designed to support high radial loads and can withstand axial loads if they feature shoulders on their inner and outer rings. They are commonly used in applications where high radial loads are present, such as in heavy machinery and industrial equipment.
High-Speed Applications
The high-speed versions of NTN cylindrical roller bearings are suitable for applications requiring high rotational speeds, such as wind turbine generators and traction motors for railway cars.
Whether you need bearings for high-radial load applications, high-speed applications, or specialised industrial applications, NTN cylindrical roller bearings with Global Bearings are the perfect solution.
