Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • One-Way Rotation Mechanism: Enables smooth unidirectional rotation via the sprag clutch design, preventing reverse motion while supporting high axial and radial loads.
  • Friction Reduction: Features deep groove ball bearings made of durable bearing steel to minimize friction and wear in rotating machinery components.

Key features

  • 1. Material Technology: Corrosion-Resistant Bearing Steel

    • With high-grade bearing steel construction, this FN Series clutch ensures exceptional durability and resistance to wear in harsh industrial environments. The material outperforms standard steel in fatigue strength, extending service life by ~30% under continuous use*.

  • 2. Interactive Design: One-Way Sprag Clutch Mechanism

    • With its automatic one-way engagement/disengagement design, the FN 442 Z enables seamless power transmission in industrial machinery. Unlike conventional clutches requiring manual adjustment, this design reduces downtime and enhances operational efficiency.

  • 3. Performance Parameters: Precision P0 Grade Accuracy

    • Engineered to P0 precision standards, this bearing delivers ultra-precise rotational alignment, minimizing vibration and noise by up to 25% compared to lower-grade bearings*. Ideal for high-precision machinery like motors and gearboxes.

  • 4. Scenario Solutions: Industrial-Grade Load Handling

    • With a 46mm outer diameter and 20mm thickness, this clutch is optimized for heavy-duty industrial applications. Its sealed structure and deep groove design allow continuous operation under high loads, outperforming open bearings prone to contamination in dusty environments*.

  • 5. Certification Standards: Compliance with Industrial Specifications

    • Constructed to meet industry standards for mechanical components, the FN 442 Z ensures compatibility with global machinery specifications. The sealed design also aligns with environmental protection norms for reduced lubricant leakage.
