63804zz Bearing Product Overview & Core Advantages
The 63804zz is a single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. As a metric bearing, it features a shielded design on both sides, offering effective protection against contamination. Its primary strengths lie in its ability to handle significant radial loads, its ABEC-1 precision class for consistent operation, and its compact dimensions (20mm bore, 32mm OD, 10mm width), making it an ideal choice for applications demanding a balance of performance, durability, and space efficiency.
Model Code Breakdown
- 63804: Basic model number denoting a single row deep groove ball bearing with a 20mm bore diameter and 32mm outside diameter.
- zz: Indicates that the bearing is equipped with non-contact steel shields (Z-shields) on both sides. This provides good protection against coarse contaminants while maintaining low friction and allowing for high limiting speeds.
63804zz Bearing Structural Features & Performance Benefits
Constructed from high-grade chrome steel for both rings and balls, and featuring a durable stainless steel cage, the 63804zz is built for longevity. The deep groove raceway geometry is optimized for handling radial dynamic loads up to 904 lbf and radial static loads up to 554 lbf. The non-contact ZZ shields effectively protect the internal components, extending bearing life. With a standard C0 radial internal clearance (0.006mm to 0.020mm), it is suited for most general applications. Its limiting speed of 25,000 rpm makes it a capable choice for high-speed operation, though proper lubrication is required to achieve this performance.
63804zz Bearing Typical Application Areas
This versatile bearing is commonly found in:
- Small Electric Motors and Gearboxes
- Power Tools
- Pumps and Compressors
- Conveyor Systems
- Office Machinery and Computer Fans
- Agricultural Machinery
