6004-2RSH/GFF/R806 Bearing Product Overview & Core Advantages
The 6004-2RSH/GFF/R806 is a sealed single row deep groove ball bearing designed for reliable performance in demanding applications. Engineered to primarily handle radial loads, this metric bearing features a robust construction from chrome steel for durability. Its key advantages include a high limiting speed of 17,000 rpm and compliance with ABEC 1 | ISO P0 tolerance standards, ensuring consistent operation and high reliability. The sealed design protects against contamination, making it a versatile choice for various industrial settings.
6004-2RSH/GFF/R806 Bearing Model Code Explained, Specifications & Naming Convention
- 6004: Basic model number denoting a single row deep groove ball bearing with a 20mm bore, 42mm OD, and 12mm width.
- 2RSH: Signifies that the bearing is equipped with two contact seals (RSH type) on both sides, providing superior protection against contaminants and moisture.
- GFF: Indicates the use of a special low-torque, food-grade fluorinated grease lubrication, suitable for the specified temperature range and offering long-term lubrication life.
- R806: Denotes a specific internal clearance group (CN standard), optimized for general operating conditions and ensuring proper fit and performance.
6004-2RSH/GFF/R806 Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing delivers high strength and resistance to wear, contributing to a long service life under radial dynamic loads up to 2113 lbf.
Enhanced Sealing & Lubrication: The 2RSH contact seals effectively prevent the ingress of contaminants and retain the GFF food-grade grease, enabling maintenance-free operation and reliable performance in dusty or humid environments.
Precision & Speed: Built to ABEC 1 | ISO P0 tolerance class, the bearing ensures smooth and quiet operation, supporting high-speed applications with a limiting speed of 17,000 rpm.
Optimal Internal Clearance: The CN standard radial internal clearance (as specified by R806) provides an ideal fit for most applications, reducing noise and vibration while accommodating thermal expansion.
6004-2RSH/GFF/R806 Bearing Typical Application Areas
