Product Description

Key Features of K182213 Radial Needle Roller and Cage Assembly

(Custom configurations available upon request.)

High-Speed Performance
K182213 is a radial needle roller and cage assembly, ideal for applications where limited space and high rotational speed are required.
Compact & Lightweight
No outer or inner ring – designed to run directly on hardened and ground shaft and housing bores, saving space and weight.
Excellent Load Carrying Capacity
Despite its compact size, the needle rollers are tightly packed to handle high radial loads with minimal deflection.
Steel Cage Guided Design
Ensures precise roller guidance, reduces friction, and prevents skewing during operation.
Flexible Design Integration
Commonly used in automotive transmissions, gearboxes, pumps, and power tools, where custom integration is needed.

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.

7. How do I maintain ceramic bearings?
Ceramic bearings require minimal maintenance, but to ensure longevity:

  Use the correct lubrication when necessary.
