61828-2RS1/C3 Bearing Product Overview & Core Advantages
The 61828-2RS1/C3 is a metric single row deep groove ball bearing engineered for high reliability in demanding applications. Its key advantage lies in its sealed design (2RS1) which provides robust protection against contaminants, combined with a C3 radial internal clearance for optimal performance under operational thermal expansion. This bearing is designed to handle primarily radial loads efficiently, featuring a compact cross-section that saves space without compromising on its substantial dynamic and static load ratings. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance and is ready for use with its pre-lubricated seals, making it an excellent choice for general industrial machinery requiring dependable, long-lasting operation.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 61828 | Basic series designation for a metric, single row deep groove ball bearing with a specific boundary dimension series (180 series: thin section, 28 bore code). |
| 2RS1 | Indicates the bearing is fitted with contact seals on both sides. The RS1 type seal is made of Nitrile Rubber (NBR) and provides effective protection against dust and moisture ingress. |
| /C3 | Denotes a radial internal clearance greater than normal (C3 group). This is beneficial for applications where thermal expansion of the shaft and housing is expected, preventing pre-load and ensuring smooth operation. |
61828-2RS1/C3 Bearing Structural Features & Performance Benefits
- Robust Sealing for Contaminant Exclusion: The 2RS1 double-contact seals are a critical feature, effectively shielding the internal rolling elements and raceways from contaminants like dust and splashing fluids. This significantly enhances bearing service life in harsh environments and reduces maintenance needs.
- Optimized Internal Clearance for Thermal Stability: The C3 radial internal clearance is engineered to accommodate the thermal expansion of adjacent components during operation. This prevents undesirable pre-loading, reduces friction and heat generation, and contributes to stable performance across its specified temperature range.
- High-Grade Material Construction: All core components—rings, balls, and cage—are manufactured from chrome steel, ensuring high hardness, wear resistance, and consistent performance under the specified radial dynamic and static load ratings.
- Compact and Lightweight Design: With a 18 mm width and a weight of only 0.82 kg, this bearing offers a high load capacity in a minimal space, making it ideal for compact machinery designs.
61828-2RS1/C3 Bearing Typical Application Areas
The 61828-2RS1/C3 is versatile and finds use in a wide range of industrial sectors, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
