6214-2RS1/C3W64 Bearing Product Overview & Core Advantages
The 6214-2RS1/C3W64 is a single row deep groove ball bearing engineered for exceptional reliability in demanding applications. This sealed bearing features a robust construction with solid oil lubrication, providing long-term, maintenance-free operation. Its C3 radial internal clearance makes it suitable for applications with thermal expansion or where interference fits are used, ensuring stable performance under varying operational conditions. Designed to handle primarily radial loads, this bearing offers a high limiting speed and consistent performance across a wide temperature range, making it an ideal choice for industrial machinery requiring durability and precision.
6214-2RS1/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 6214 | Basic designation: 70mm bore, 125mm OD, 24mm width | Standard dimensions for easy interchangeability |
| 2RS1 | Contact rubber seals on both sides | Superior contamination protection and grease retention |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits |
| W64 | Solid oil lubrication system | Maintenance-free operation with excellent lubricant retention |
6214-2RS1/C3W64 Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design enables efficient radial load distribution and accommodates moderate axial loads in both directions, providing versatile load-handling capability.
Double Contact Seals (2RS1): Nitrile rubber seals make full contact with the inner ring, creating an effective barrier against contaminants while retaining lubrication, significantly extending bearing service life in harsh environments.
Solid Oil Lubrication (W64): The bearing is filled with a polymer matrix saturated with premium lubricating oil, eliminating leakage and providing consistent lubrication throughout the operating temperature range (-30° to 120°C). This technology ensures maintenance-free operation and prevents lubricant washout.
C3 Internal Clearance: The increased radial internal clearance accommodates differential thermal expansion between bearing components and housing/shaft fits, preventing preload conditions that could lead to premature failure.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance class with chrome steel rings, balls, and cage, ensuring consistent performance and dimensional stability under load.
6214-2RS1/C3W64 Bearing Typical Application Areas
Electric Motors: Ideal for industrial motor applications requiring sealed, maintenance-free operation and reliable performance at moderate speeds.
Material Handling Equipment: Commonly used in conveyor systems, pulleys, and rollers where contamination protection is essential.
Agricultural Machinery: Suitable for farm equipment operating in dusty conditions, benefiting from the sealed construction and solid oil lubrication.
Industrial Fans and Blowers: Provides reliable performance in ventilation systems with continuous operation requirements.
General Industrial Machinery: Versatile enough for use in pumps, gearboxes, and other machinery where radial load capacity and sealed protection are primary considerations.
