SD100AR0 Bearing Product Overview & Core Advantages
The SD100AR0 is a thin-section angular contact ball bearing engineered for applications requiring high precision and space optimization. This stainless steel bearing features a single-row design with a 30° contact angle, enabling it to support significant combined loads—both radial and axial. Its compact cross-section (0.5" width relative to 10" bore) makes it ideal for high-rigidity systems where weight and space are critical constraints. Manufactured to ABEC-1 precision standards, it delivers reliable performance in demanding environments.
SD100AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SD100 | Bearing series designation for thin-section angular contact bearings |
| A | 30° contact angle configuration |
| R0 | Radial internal clearance specification (0.0000-0.0005") |
SD100AR0 Bearing Structural Features & Performance Benefits
Premium Material Construction: Manufactured entirely from stainless steel (rings and balls) with a brass cage, providing excellent corrosion resistance and durability in harsh environments.
High Load Capacity: The 30° contact angle and optimized raceway geometry enable superior combined load handling, with static load ratings of 8,290 lbf radial and 7,500 lbf axial.
Precision Engineering: ABEC-1 tolerance class ensures consistent performance and smooth operation, while the controlled radial clearance (0.0000-0.0005") maintains optimal preload characteristics.
Space-Efficient Design: As part of the Reali-Slim series, it offers maximum load capacity in minimal cross-section, achieving significant weight reduction (1.87 lbs) without compromising performance.
