SD075AR0 Bearing Product Overview & Core Advantages
The SD075AR0 is a thin-section angular contact ball bearing engineered for applications requiring high precision and space optimization. Constructed from stainless steel with a brass cage, this single-row bearing is designed to handle combined loads, efficiently supporting significant radial and axial forces simultaneously. Its 30° contact angle provides excellent axial load capacity while maintaining operational stability. With an ABEC-1 precision class and consistent performance across a wide temperature range (-30°C to 110°C), it delivers reliable performance in demanding environments where corrosion resistance and dimensional accuracy are critical.
SD075AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SD075 | Bore diameter designation (7.5 inches) |
| A | Angular contact design with 30° contact angle |
| R0 | Reali-Slim series with standard cross-section (0.5" width) |
SD075AR0 Bearing Structural Features & Performance Benefits
Thin-Section Design: With a consistent 0.5" cross-section across various bore sizes, this bearing enables compact, lightweight machinery designs while maintaining structural integrity.
High Load Capacity: The 30° contact angle configuration provides exceptional axial load handling (6250 lbf static) while maintaining substantial radial load capacity (2536 lbf dynamic), making it ideal for combined loading applications.
Precision Performance: Manufactured to ABEC-1 tolerance standards with tight dimensional control (bore/OD tolerance: -0.0012" to 0"), ensuring smooth operation and accurate positioning in precision equipment.
Corrosion Resistance: Constructed entirely from stainless steel components (rings and balls) with brass cage, providing excellent resistance to corrosion and chemical exposure in harsh environments.
Optimized Lubrication: Pre-lubricated design ensures immediate operational readiness and consistent performance across the specified temperature range.
