S6801 Bearing Product Overview & Core Advantages
The S6801 is a metric single row deep groove ball bearing designed for precision applications requiring compact dimensions and reliable performance. Manufactured entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. This bearing is engineered to primarily handle radial loads and is characterized by its ABEC-1 precision class, ensuring smooth operation and high rotational accuracy. Its open design allows for versatile lubrication options to suit specific application needs, making it a robust solution for compact assemblies demanding high reliability.
S6801 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| S6801 | Basic model number denoting a metric, single row deep groove ball bearing with a 12mm bore, 21mm OD, and 5mm width. |
| Open (Seal Type) | No integral seals or shields. This allows for higher limiting speeds and custom lubrication but requires a clean operating environment or external sealing. |
| ABEC-1 | Specifies the precision tolerance class, ensuring controlled dimensions and runout for smooth, accurate operation. |
| C0 (Radial Clearance) | Indicates a standard, normal range of internal clearance (0.003mm to 0.018mm), suitable for most general applications. |
S6801 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The use of stainless steel for all critical components provides superior corrosion resistance, making the bearing ideal for applications exposed to moisture, chemicals, or washdown environments. This also contributes to a long service life.
- High-Speed Capability: The open design, combined with a precision-stamped stainless steel cage, minimizes friction and allows for a high limiting speed of 27,000 rpm, enabling use in demanding, high-velocity scenarios.
- Precision Performance: Manufactured to ABEC-1 tolerances, this bearing offers low noise and vibration levels, contributing to the overall accuracy and smoothness of the host machinery.
- Radial Load Capacity: The deep groove raceway geometry is optimized to efficiently support significant radial dynamic load ratings (388 lbf) and static loads (210 lbf) within its compact footprint.
S6801 Bearing Typical Application Areas
This bearing's compact size, high-speed performance, and corrosion resistance make it suitable for a wide range of precision equipment, including:
- Small electric motors and spindles
- Medical and dental handpieces
- Precision instruments and optical devices
- Food processing and packaging machinery
- Office automation equipment (e.g., scanners, printers)
- Robotics and miniature gearboxes
