S687 Bearing Product Overview & Core Advantages
The S687 is a metric single row deep groove ball bearing engineered for precision radial load applications. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. This bearing is characterized by its compact design with a 7 mm bore and a low cross-section, making it ideal for space-constrained, high-speed applications up to 36,000 rpm. Its ABEC1 precision class ensures reliable performance in instruments and small machinery requiring smooth operation and consistent accuracy.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| S687 | The base bearing designation, indicating a specific size and type of single row deep groove ball bearing. |
| Open (Seal Type) | The bearing is unsealed ("Open"), allowing for custom lubrication schemes but requiring a clean operating environment. |
| MC3 (Clearance) | Specifies a radial internal clearance group of 0.002mm to 0.013mm, suitable for most general applications. |
S687 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The optimized stainless steel cage and balanced design contribute to a high limiting speed of 36,000 rpm, making it an excellent high-speed bearing for miniature applications.
- Corrosion Resistance: The all-stainless-steel construction provides superior protection against rust and corrosion, ensuring longevity in harsh or wash-down environments.
- Precision Performance: Manufactured to ABEC1 tolerance class with controlled radial internal clearance, this bearing delivers smooth, low-vibration, and low-noise operation.
- Radial Load Capacity: As a deep groove ball bearing, it is primarily designed to support significant radial dynamic load ratings (202 lbf) efficiently.
S687 Bearing Typical Application Areas
This precision bearing is ideally suited for:
- Small electric motors and spindles
- Precision instruments and optical encoders
- Medical and dental handpieces
- Radio-controlled models (drones, RC cars)
- Office machinery and small precision gearboxes
