Product Description

Key Features of CF Series Stud-Type Cam Followers | Needle Roller Track Bearings

(Custom configurations available upon request.)

Stud-Type Cam Follower Design
Equipped with a threaded bolt (stud shaft) for secure mounting to machine arms, guides, and cam systems. Suitable for oscillating, tracking, or linear motion.
High Radial Load Capacity
Features needle roller elements that provide superior load distribution, compact dimensions, and resistance to heavy dynamic or static forces.
Outer Ring with Crowned Profile
The slightly curved (crowned) outer surface reduces edge loading during misalignment or deflection—enhancing durability in high-speed applications.
Sealed or Lubricated Options
Available with RS seals (e.g., CF-1/2-N, CF-5/8-N) or open/greasable structures (e.g., CF-2-1/4-S). Many models come with grease nipples for easy maintenance.
Heat-Treated & Ground Components
Made from high-quality bearing steel (GCr15 / AISI 52100), heat-treated for wear resistance, dimensional stability, and long service life.

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.
  Keep them clean and free from contaminants.
