SC140AR0 Bearing Product Overview & Core Advantages
The SC140AR0 is a thin-section angular contact ball bearing engineered for applications requiring high precision and space optimization. Manufactured from stainless steel with a brass cage, this single-row bearing is designed to handle combined loads efficiently, with its 30° contact angle providing excellent axial load capacity. Its ABEC-1 precision and inch-series dimensions make it ideal for compact, high-reliability systems where accurate rotational motion is critical. The bearing comes pre-lubricated for immediate operation.

SC140AR0 Bearing Structural Features & Performance Benefits
Thin-Section Design: With a minimal cross-section (0.375" width relative to 14" bore), this bearing enables compact and lightweight machinery designs without sacrificing performance.
High Load Capacity: The 30° contact angle and optimized raceway geometry provide superior axial load rating (6170 lbf static) while maintaining substantial radial load capacity (8490 lbf static).
Precision Performance: Manufactured to ABEC-1 tolerance standards with tight dimensional controls (±0.0014" on diameters) ensuring smooth, accurate rotation with minimal runout.
Corrosion Resistance: Complete stainless steel construction (rings and balls) provides excellent corrosion resistance for harsh environments and cleanroom applications.
Enhanced Stability: The brass cage ensures stable ball guidance and reliable operation across the temperature range of -30°C to 110°C.
SC140AR0 Bearing Typical Application Areas
- Aerospace & Defense: Gimbal systems, satellite mechanisms, and precision instrumentation
- Semiconductor Manufacturing: Wafer handling robots, precision stages, and cleanroom equipment
