618/530 MA/C3 Bearing Product Overview & Core Advantages
The 618/530 MA/C3 is a single row deep groove ball bearing engineered for demanding industrial applications requiring high radial load capacity and reliable performance. This open-type bearing features a machined metal cage (MA) for enhanced strength and stability under high rotational speeds. Its C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used, ensuring optimal performance across a wide operating temperature range. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent precision and durability.
618/530 MA/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Implication |
|---|---|---|
| 618 | Deep Groove Ball Bearing Series | Standard design optimized for radial loads |
| 530 | Bore Diameter: 530 mm | Large bore size for heavy-duty shafts |
| MA | Machined Brass Cage | Superior cage strength and guidance at high speeds |
| C3 | Radial Internal Clearance greater than Normal | Accommodates thermal expansion in heated applications |
618/530 MA/C3 Bearing Structural Features & Performance Benefits
- High Load Capacity Design: The deep groove raceway and single row construction enable excellent radial dynamic load rating of 74,637 lbf and radial static load rating of 147,250 lbf, making it ideal for heavy machinery.
- Optimized High-Speed Performance: The machined brass cage (MA) provides exceptional dimensional stability and reduced friction, supporting a limiting speed of 1,400 rpm while maintaining smooth operation.
- Precision Engineering: Manufactured from chrome steel for both rings and balls, ensuring high hardness, wear resistance, and long service life under continuous operation.
- Flexible Installation & Operation: The C3 clearance and open design allow for thermal expansion compensation and custom lubrication strategies, providing versatility across different operating conditions.
