6318-2RS1/C3 Bearing Product Overview & Core Advantages
The 6318-2RS1/C3 is a sealed deep groove ball bearing designed for robust performance in demanding industrial applications. As a single row bearing, it offers an optimal balance of high load capacity and operational reliability. Its primary advantage lies in its ability to accommodate significant radial loads, while the integrated sealing provides excellent protection against contaminants. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing ensures consistent performance and is an ideal choice for applications requiring dependable operation under standard precision conditions.
6318-2RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6318 | Basic bearing designation indicating a medium series, deep groove ball bearing with a 90mm bore. |
| 2RS1 | Signifies contact seals on both sides. The "RS1" type seals are made of Nitrile Rubber (NBR), providing effective protection against dust and moisture ingress. |
| C3 | Indicates a greater than normal radial internal clearance. This is beneficial for applications with thermal expansion, such as in electric motors, or where interference fits are used. |
6318-2RS1/C3 Bearing Structural Features & Performance Benefits
- Robust Load Capacity: With a dynamic load rating of 32,148 lbf and a static load rating of 24,055 lbf, this bearing is engineered to handle substantial radial forces, ensuring long service life in heavy-duty operations.
- Effective Sealing: The 2RS1 contact seals effectively shield the internal components from contaminants like dust and dirt, making the bearing suitable for harsh environments and contributing to its longevity.
- Optimized Internal Clearance: The C3 clearance provides operational stability in applications prone to thermal expansion, preventing premature failure due to excessive preload.
- High-Quality Construction: All critical components, including rings, balls, and cage, are manufactured from chrome steel, ensuring high strength, durability, and resistance to wear.
- Standard Precision: Conforming to ABEC 1 | ISO P0 tolerance class, it delivers reliable and consistent performance for a wide range of general industrial applications.
