6305-2RSH/VA947 Bearing Product Overview & Core Advantages
The 6305-2RSH is a sealed single row deep groove ball bearing engineered for high-performance industrial applications. This precision bearing is designed to handle significant radial loads and moderate axial loads in both directions. Its key advantages include a compact design, high operational reliability, and long service life due to its integrated sealing and pre-lubrication. Manufactured to a P6 tolerance class, it ensures precise running accuracy, making it ideal for applications demanding high rotational stability.
6305-2RSH/VA947 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Code | Technical Meaning |
|---|---|---|
| Basic Designation | 6305 | Standard single row deep groove ball bearing with 25mm bore, 62mm OD, 17mm width |
| Sealing | 2RSH | Double Seals (RSH type) on both sides, providing superior protection against contamination and grease leakage |
6305-2RSH/VA947 Bearing Structural Features & Performance Benefits
Optimized Sealing System: The 2RSH seals are manufactured from NBR rubber and are contact seals, offering excellent protection against contaminants like dust and moisture, while effectively retaining the lubricant. This makes the bearing suitable for harsh environments.
High Load Capacity: The deep groove raceway and high-quality chrome steel construction enable high radial dynamic load ratings (5261 lbf) and static load ratings (2608 lbf), ensuring durability under demanding conditions.
Precision and Speed: Built to P6 tolerance class with a CN radial internal clearance, this bearing provides precise and quiet operation. The stainless steel cage and optimized grease lubrication contribute to a high limiting speed of 7,500 rpm.
Maintenance-Free Operation: Pre-lubricated with high-quality grease and sealed for life, the bearing requires no relubrication, reducing maintenance costs and downtime.
