61818/C3 Bearing Product Overview & Core Advantages
The 61818/C3 is a single row deep groove ball bearing designed for reliable performance in general industrial applications. This metric bearing excels in handling primarily radial loads while also accommodating moderate axial loads in both directions. Its open design allows for versatile lubrication options and facilitates high-speed operation. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a cost-effective solution without compromising on essential performance and durability, making it ideal for applications requiring a balance of precision and value.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 61818 | Standard series designation for a single row deep groove ball bearing with a 90mm bore and 115mm outside diameter. |
| /C3 | Indicates a greater than normal radial internal clearance. This is beneficial for applications involving thermal expansion, such as in electric motors or where bearing fits may cause clearance reduction. |
61818/C3 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The open structure and chrome steel cage minimize friction and allow for a limiting speed of 7,000 rpm, making it suitable for demanding rotational applications.
- Robust Load Capacity: With a dynamic load rating of 4384 lbf and a static load rating of 3822 lbf, this bearing provides reliable support for significant radial loads.
- Precision & Reliability: Manufactured to ABEC 1 (ISO P0) tolerance class, it ensures consistent running accuracy and smooth operation, contributing to overall system reliability.
- Versatile Application Range: The specified C3 radial clearance and a wide operating temperature range (-30°C to 120°C) make it adaptable to environments with thermal fluctuations.
- Material Integrity: Constructed entirely from chrome steel for rings, balls, and cage, it offers excellent hardness, wear resistance, and long service life.
