61928 MA/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| MA | Machined brass cage, pressed and riveted | Provides high strength and excellent guidance, suitable for high-speed applications and demanding operating conditions. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in applications with high operating temperatures or heavy loads, preventing premature failure. |
61928 MA/C3 Bearing Structural Features & Performance Benefits
- High Load Capacity: The deep groove raceway and high-quality chrome steel construction enable the bearing to handle significant radial dynamic loads (14,905 lbf) and radial static loads (16,186 lbf).
- Optimized for Speed: The machined metal cage (MA) ensures stable ball guidance, contributing to a high limiting speed of 5,600 rpm, making it a capable high-speed bearing.
- Robust Construction: Components made from chrome steel offer high hardness and wear resistance. The open (seal type: Open) design is ideal for applications where the bearing is part of a centralized lubrication system.
- Precision & Reliability: Manufactured to ABEC 1 precision class, it guarantees running accuracy and consistent performance, which is critical for the smooth operation of machinery.
