SC070AR0 Bearing Product Overview & Core Advantages
The SC070AR0 is a thin-section angular contact ball bearing engineered for applications demanding high precision and space optimization. As part of the Reali-Slim Stainless Steel series, this single-row bearing excels in handling combined loads, specifically significant axial loads in one direction due to its 30° contact angle. Its corrosion-resistant stainless steel construction and ABEC-1 precision make it ideal for high-rigidity applications where compact cross-sections and reliable performance are critical.
SC070AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SC070 | Indicates the specific bearing size series (7" bore, 7.75" OD, 0.375" width) |
| A | Signifies Angular Contact design with 30° contact angle |
| R0 | Denotes Open (unsealed) construction and standard internal clearance |
SC070AR0 Bearing Structural Features & Performance Benefits
Thin-Section Design: The compact cross-section (0.375" width) enables significant space and weight savings in precision machinery without compromising performance.
High Load Capacity: The 30° contact angle and optimized raceway geometry provide excellent axial load capacity (3930 lbf static) while maintaining substantial radial load handling (4320 lbf static).
Corrosion Resistance: Manufactured entirely from stainless steel (rings and balls) with brass cage, offering superior corrosion resistance for harsh environments and extended service life.
Precision Performance: ABEC-1 tolerance class ensures consistent running accuracy and high rigidity for applications requiring precise rotational motion.
SC070AR0 Bearing Typical Application Areas
- Robotics and Automation: Joint actuators, rotary tables, and precision positioning systems
- Aerospace Systems: Guidance mechanisms, control surface actuators, and instrument rotors
- Medical Equipment: CT scanners, surgical robots, and diagnostic instrument rotors
- Semiconductor Manufacturing: Wafer handling robots and precision positioning stages
