Product Description

Key Features of NUP Series Cylindrical Roller Bearing

(Custom configurations available upon request.)

Cylindrical Roller Design:

High radial load-carrying capacity due to the cylindrical roller design.
Minimal friction during operation for improved efficiency.
Axial Load Capability:

Designed to support limited axial loads in one direction.
Can locate the shaft axially in both directions when used with a fixed inner or outer ring.
Integral Flanges:

The outer ring has two integral flanges, while the inner ring has one flange and a loose flange ring (NUP configuration).
Allows axial displacement of the shaft relative to the housing.
Separable Design:

The separable inner and outer rings simplify installation and maintenance.
Interchangeability of components allows flexible assembly options.
High-Speed Performance:

Suitable for high-speed applications due to low friction and efficient heat dissipation.
Robust Materials:

Made from high-grade bearing steel for excellent wear resistance and durability.
Standardized Dimensions:

Conforms to ISO standards, ensuring compatibility with global equipment designs.
Lubrication:

Supports oil or grease lubrication, enhancing versatility in different operating environments.
Applications:

Widely used in gearboxes, electric motors, pumps, compressors, and machinery requiring precise shaft positioning.

FAQ

1. What are ceramic bearings?
Ceramic bearings are bearings made from advanced ceramic materials such as Zirconia (ZrO2) or Silicon Nitride (Si3N4). They are known for their high strength, wear resistance, and ability to perform in extreme conditions.

2. What are the advantages of ceramic bearings over steel bearings?
Ceramic bearings offer several advantages, including:

  Higher Durability: Resistant to wear, corrosion, and high temperatures.
  Lighter Weight: Up to 40% lighter than steel bearings.
  Non-Magnetic & Electrically Insulating: Ideal for sensitive applications.
  Low Friction: Reduces energy loss and heat generation.
3. In which industries are ceramic bearings commonly used?
Ceramic bearings are widely used in:

  Packaging equipment
  Renewable energy (e.g., wind turbines)
  Aerospace and automotive
  Medical devices
  Chemical processing
  High-precision tools
4. Can ceramic bearings handle high temperatures?
Yes, ceramic bearings are highly resistant to heat and can operate in temperatures exceeding 1,000°C, depending on the material used.

5. Are ceramic bearings suitable for corrosive environments?
Absolutely! Ceramic bearings are non-reactive to most chemicals, making them ideal for use in highly corrosive environments.

6. What is the lifespan of ceramic bearings?
Ceramic bearings typically last much longer than steel bearings due to their wear resistance and durability. However, the exact lifespan depends on the operating conditions and maintenance practices.
