6801 Bearing Product Overview & Core Advantages
The 6801 is a single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity. Its compact design, featuring a 12 mm bore, 21 mm outside diameter, and a narrow 5 mm width, makes it ideal for space-constrained assemblies. Manufactured to ABEC-1 precision tolerances with chrome steel rings and balls, this bearing delivers consistent operation and extended service life. Its C0 radial internal clearance provides a versatile fit for a wide range of standard applications.
6801 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6801 | Standard designation for a single row deep groove ball bearing with a 12mm bore and 21mm OD. |
| Open (Seal Type) | The bearing is unsealed, allowing for high-speed operation and permitting the application of specific lubricants suited to the operating environment. |
| ABEC-1 | Indicates the precision tolerance class, ensuring controlled running accuracy for general precision applications. |
| C0 (Clearance) | Specifies the standard radial internal clearance range (0.003mm to 0.018mm) for normal operating conditions and fits. |
6801 Bearing Structural Features & Performance Benefits
Optimized for Radial Loads: The deep groove raceway and single row construction are engineered to efficiently support significant radial dynamic load ratings of 432 lbf, making it a robust choice for primary radial force applications.
High-Speed Capability: With a limiting speed of 36,000 rpm and a stainless steel cage, the 6801 is capable of stable operation at high rotational velocities, minimizing friction and heat generation.
Precision and Durability: The use of chrome steel for both rings and balls provides high hardness and wear resistance. The ABEC-1 tolerance ensures consistent dimensional accuracy, contributing to smooth and vibration-free running.
Application-Specific Lubrication: As an open bearing, it offers the flexibility for users to select the optimal lubricant (grease or oil) to achieve maximum performance and life under specific temperature conditions (-30°C to 110°C).
6801 Bearing Typical Application Areas
- Electric Motors: Small to medium-sized motors, fans, and blowers requiring reliable support for rotor shafts.
- Precision Instruments: Office automation equipment, medical devices, and optical instruments where compact size and smooth operation are critical.
- Power Tools: Drills, grinders, and other handheld tools that demand high-speed performance and durability.
- General Machinery: Pumps, gearboxes, and conveyors in industrial settings for supporting shafts under radial loads.
