S63801 Bearing Product Overview & Core Advantages
The S63801 is a metric single row deep groove ball bearing designed for high-performance applications requiring precision and reliability. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its core advantages include a high limiting speed of 32,400 rpm and the ability to handle significant radial dynamic loads (388 lbf). As an open type bearing, it allows for optimal lubrication management, making it suitable for high-speed, precision machinery where controlled lubrication is critical.

|---|---|
| S6 | Indicates a series of stainless steel deep groove ball bearings. |
| 3801 | Denotes the bearing size: 12mm bore, 21mm outside diameter, 7mm width. |
| Open | No seals or shields, allowing for high-speed operation and custom lubrication. |
S63801 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The rings, balls, and cage are made of stainless steel, providing superior corrosion resistance and enabling operation in harsh environments within a wide temperature range (-86 to 230 °F).
- High-Speed Capability: The open design and precision ABEC-1 tolerance class minimize friction and heat generation, supporting the high limiting speed.
- Radial Load Capacity: The deep groove raceway and robust construction enable efficient handling of the specified radial dynamic and static loads.
- Precision & Consistency: Manufactured to ABEC-1 precision class standards with a C0 radial internal clearance, ensuring reliable and smooth operation.
S63801 Bearing Typical Application Areas
This bearing is ideal for applications demanding high rotational speeds, corrosion resistance, and precision. Common uses include:
- High-speed spindles in dental handpieces and small machinery
- Precision instruments and optical devices
- Food processing and medical equipment (due to stainless steel construction and ROHS/REACH compliance)
- Small electric motors and pumps
