SC180AR0 Bearing Product Overview & Core Advantages
The SC180AR0 is a high-performance thin section angular contact ball bearing engineered for precision applications requiring exceptional rigidity and accuracy. Manufactured from stainless steel with a brass cage, this single row bearing is specifically designed to handle significant combined loads, including high thrust capacities in one direction. Its compact bearing dimensions (18" bore, 18.75" OD, 0.375" width) and ABEC-1 precision make it an ideal solution for space-constrained, high-reliability machinery.
SC180AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SC | Stainless Steel Construction (rings and balls) |
| 180 | Bore Diameter: 18 inches |
| A | Angular Contact design with a 30° contact angle |
| R | Reali-Slim thin section series |
| 0 | Open (unsealed) construction |
SC180AR0 Bearing Structural Features & Performance Benefits
This bearing's performance is derived from its optimized structural design:
- High Rigidity & Load Capacity: The angular contact design with a 30° contact angle provides superior resistance to combined radial and axial loads, with a static axial load rating of 7280 lbf and a high static load moment of 31410 lbf.
- Precision Engineering: Built to ABEC-1 tolerance standards with tight bore and outside diameter tolerances (-0.0016" to 0"), ensuring smooth operation and accurate positioning in precision applications.
- Corrosion Resistance & Durability: The use of stainless steel for all bearing components and a brass cage offers excellent corrosion resistance and reliable performance in challenging environments.
- Optimized for Thin-Section Applications: The Reali-Slim design provides a large diameter with a minimal cross-section, maximizing space utilization without compromising on load carrying capacity.
SC180AR0 Bearing Typical Application Areas
The SC180AR0 is ideally suited for demanding applications across various industries, including:
- Aerospace & Defense: Gimbal systems, radar platforms, and rotary actuators
- Semiconductor Manufacturing: Precision wafer handling robots and stages
- Medical Equipment: CT scanner gantries and robotic surgical arms
