6317-2RS1/C3 Bearing Product Overview & Core Advantages
The 6317-2RS1/C3 is a single row deep groove ball bearing designed for robust performance in demanding applications. Engineered to primarily handle radial loads, its sealed construction ensures long-term reliability and protection against contaminants. A key feature is its C3 radial internal clearance, which accommodates thermal expansion in applications with elevated operating temperatures or where fits result in a reduction of internal clearance. This bearing offers a compact design, high limiting speed, and is manufactured to ABEC 1 | ISO P0 tolerance standards, making it a versatile and cost-effective solution for a wide range of industrial machinery.
6317-2RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
- 6317: Standard designation for a metric single row deep groove ball bearing with an 85mm bore, 180mm OD, and 41mm width.
- 2RS1: Signifies that the bearing is equipped with contact seals on both sides. The "RS1" type seals are made of Nitrile Rubber (NBR), providing effective protection against dust, dirt, and moisture ingress.
- C3: Indicates a greater than normal radial internal clearance. This is essential for applications where thermal expansion is a factor, preventing pre-loading and potential bearing failure.
6317-2RS1/C3 Bearing Structural Features & Performance Benefits
Robust Sealed Construction: The 2RS1 double-contact seals are a critical feature, creating an effective barrier that retains lubrication and excludes contaminants. This significantly extends the bearing's service life and enables reliable operation in harsh environments, reducing the need for frequent maintenance.
Optimized Internal Clearance: The C3 clearance group is a major performance advantage. It allows for stable operation under conditions that generate heat, such as high speeds or heavy loads, by providing extra space for thermal expansion of the inner ring and rolling elements. This prevents excessive friction, heat buildup, and premature failure.
High-Quality Material & Precision: Constructed entirely from chrome steel for rings, balls, and cage, this bearing ensures high strength, durability, and resistance to wear. Manufactured to ABEC 1 precision, it guarantees consistent running accuracy and smooth operation, contributing to overall machine efficiency.
6317-2RS1/C3 Bearing Typical Application Areas
The 6317-2RS1/C3 is widely used across various industries due to its sealed and robust design. Common applications include:
- Electric Motors: Ideal for both industrial and automotive electric motors where sealed protection is required.
- Industrial Gearboxes: Provides reliable support in gearboxes subject to thermal variations.
- Material Handling Equipment: Used in conveyor pulleys and other machinery operating in dusty or dirty conditions.
- Agricultural Machinery: Suitable for farm equipment exposed to weather and particulate matter.
- Pumps and Compressors: A dependable choice for pump shafts requiring protection from fluid and contaminant ingress.
