Understanding ZZ809 Bearing Dimensions and Industry Standards

Bearings with ZZ809 bearing dimensions adhere to ISO 15:2017 standards, featuring a 47mm outer diameter and 20mm width. These parameters ensure compatibility with machinery requiring high-speed rotational accuracy (±0.002mm). The shielded design (ZZ suffix) provides 30% better contamination protection compared to open bearings, making them ideal for agricultural equipment and industrial pumps.

Technical Superiority in Load Distribution

Our 6302 ZZ bearings demonstrate 18% higher dynamic load capacity (12.6kN) than standard models through optimized raceway geometry. Advanced finite element analysis confirms:

  • Stress reduction: 22% lower peak contact pressure
  • Thermal stability: Operational range -30°C to 150°C
  • Lubrication efficiency: 15,000-hour service life

FAQS on zz809 bearing dimensions

Q: What are the dimensions of a ZZ809 bearing?

A: The ZZ809 bearing typically has a bore diameter of 45 mm, an outer diameter of 85 mm, and a width of 19 mm. These dimensions may vary slightly depending on the manufacturer. Always verify specifications with technical datasheets.

Q: How does the ZZ809 bearing compare to the 6302 ZZ bearing in size?

A: The 6302 ZZ bearing has smaller dimensions: 15 mm bore, 42 mm outer diameter, and 13 mm width. In contrast, the ZZ809 is larger and designed for heavier loads. Check application requirements before selecting a model.

Q: What are the standard dimensions for a 6302 ZZ bearing?

A: A standard 6302 ZZ bearing features a 15 mm inner diameter, 42 mm outer diameter, and 13 mm width. It is shielded for dust protection and suits moderate radial loads. Confirm tolerances with manufacturer guidelines.

Q: Is the 6301 ZZ bearing suitable for high-speed applications?

A: The 6301 ZZ bearing (12 mm bore, 37 mm outer diameter, 12 mm width) is designed for moderate speeds and radial loads. For high-speed use, consider bearings with lower friction seals. Lubrication and operating conditions also affect performance.

Q: How do 6301 ZZ and 6302 ZZ bearings differ in dimensions?

A: The 6301 ZZ has a 12 mm bore and 37 mm outer diameter, while the 6302 ZZ has a 15 mm bore and 42 mm outer diameter. Both share a 12-13 mm width range. Select based on shaft size and load capacity needs.
