S635 Bearing Product Overview & Core Advantages
The S635 is a metric single row deep groove ball bearing engineered for precision radial load applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance and reliable performance. Its compact design, with a 5 mm bore and 6 mm width, makes it ideal for space-constrained assemblies requiring high rotational accuracy and smooth operation. This bearing is an optimal choice for applications demanding consistent performance under radial loads with an ABEC1 tolerance class.

S635 Bearing Structural Features & Performance Benefits
- High Precision & Smooth Operation: Manufactured to ABEC1 tolerance standards with a radial internal clearance of MC3, ensuring consistent running accuracy and low vibration.
- Robust Load Capacity: The single row deep groove raceway is optimized to handle significant radial dynamic loads (402 lbf) and radial static loads (145 lbf).
- Corrosion Resistance: All components, including rings, balls, and the cage, are made from stainless steel, making it suitable for harsh or washdown environments.
- High-Speed Capability: Features a limiting speed of 28,800 rpm, enabled by the precision-ground components and stable stainless steel cage.
- Compact and Lightweight: With a total weight of only 8.5 grams, it minimizes inertia and is perfect for high-speed, lightweight mechanisms.
S635 Bearing Typical Application Areas
This bearing is widely used in various precision instruments and compact machinery, including:
- Small Electric Motors and miniature gearboxes.
- Precision Medical Devices and dental handpieces.
- Office Automation Equipment such as printers and scanners.
- Instrumentation and optical encoders.
- Radio Control Models and drones.
