SG065AR0 Bearing Product Overview & Core Advantages
The SG065AR0 is a high-performance thin section angular contact ball bearing engineered for applications demanding precision and reliability in compact spaces. Manufactured from stainless steel with a 30° contact angle, this single-row bearing is specifically designed to handle combined loads, supporting significant radial and axial forces simultaneously. Its ABEC-1 precision class and tight dimensional tolerances ensure smooth, accurate operation, making it ideal for high-rigidity systems where space and weight are critical constraints.
SG065AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SG | Indicates the Reali-Slim thin section bearing series. |
| 065 | Specifies the bore diameter of 6.5 inches. |
| A | Denotes the 30° contact angle design. |
| R0 | Signifies standard radial internal clearance (0.0000 – 0.0005"). |
SG065AR0 Bearing Structural Features & Performance Benefits
Superior Load Capacity: The angular contact design and stainless steel construction enable the SG065AR0 to support high combined loads, with a radial dynamic load rating of 7761 lbf and an impressive axial static load rating of 17870 lbf. This makes it exceptionally capable in applications with complex force vectors.
High Rigidity & Precision: The single-row construction with a brass cage provides stable ball guidance, contributing to system rigidity and smooth rotation. Combined with ABEC-1 precision tolerances and tight bearing dimensions (6.5" bore, 8.5" OD, 1" width), it ensures minimal runout and high positional accuracy.
Corrosion Resistance & Durability: Manufactured entirely from stainless steel (rings and balls), this bearing offers excellent corrosion resistance, suitable for operating in harsh environments within a temperature range of -30°C to 110°C.
SG065AR0 Bearing Typical Application Areas
- Robotics & Automation: Precision joints, rotary actuators, and manipulator arms requiring high moment load capacity (static load moment: 41040 lbf).
- Aerospace & Defense: Gimbals, radar platforms, and guidance systems where thin section bearings save critical space and weight.
- Medical Equipment: CT scanners, MRI machines, and surgical robots demanding precision bearings with smooth, reliable motion.
- Semiconductor Manufacturing: Wafer handling robots and precision stages that benefit from the bearing's high rigidity and accuracy.
