619/750 MA Bearing Product Overview & Core Advantages
The 619/750 MA is a single row deep groove ball bearing engineered for exceptional radial load capacity and precision performance. Designed with a metric system and manufactured to a P6 tolerance class, this bearing delivers high running accuracy, making it ideal for demanding industrial applications. Its open design, combined with a stainless steel cage, ensures reliable operation and excellent suitability for high-speed scenarios. The bearing is capable of handling significant radial dynamic and static loads (171,080 lbf and 404,656 lbf respectively), providing robust and durable performance in critical machinery.
619/750 MA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 619 | Series designation for deep groove ball bearings with a low cross-section and high precision. |
| 750 | Bore diameter of 750 mm. |
| MA | Designates a brass cage (Note: Specification lists Stainless Steel cage, confirming cage material is critical for application). |
Note: The "Open" seal type and "None" for lubrication indicate the bearing is supplied without seals or grease, allowing for custom lubrication solutions tailored to specific operational environments.
619/750 MA Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row deep groove construction and robust chrome steel rings and balls enable the bearing to support substantial radial dynamic and static loads, ensuring stability and long service life under heavy-duty conditions.
- Precision & High-Speed Capability: Manufactured to P6 tolerance with a standard CN radial internal clearance, this bearing offers high running accuracy. The standard limiting speed of 850 rpm is supported by the low-friction design and the use of a durable cage material.
- Material & Durability: Components made from chrome steel provide excellent wear resistance and hardness. The cage material contributes to the bearing's overall reliability and performance in various operating temperatures (-30°C to 120°C).
- Compliance & Safety: The bearing is compliant with ROHS and REACH regulations, ensuring it meets modern environmental and safety standards for industrial use.
