6301-2Z Bearing Product Overview & Core Advantages
The 6301-2Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This metric bearing features integral shielded seals for robust contamination protection. Engineered with P6 tolerance class precision, it delivers high running accuracy and reliability. Its core advantages include the ability to handle significant radial loads, high-speed operation with a limiting speed of 22,000 rpm, and long service life due to its pre-lubricated, shielded design that minimizes maintenance requirements.
6301-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Significance |
|---|---|---|
| 6301 | Basic Bearing Series & Size | Denotes a medium-duty, single row deep groove ball bearing with a 12mm bore, 37mm OD, and 12mm width. |
| 2Z | Shielded on Both Sides | Indicates the bearing is equipped with non-contact steel shields on both sides, providing excellent protection against dust and debris while allowing for high-speed operation. |
6301-2Z Bearing Structural Features & Performance Benefits
Optimized for Radial Loads: The single row deep groove raceway geometry is fundamentally designed to support high radial dynamic load ratings of 2271 lbf, making it a robust choice for radial force transmission.
High-Speed Capability: The combination of a lightweight stainless steel cage, precision P6 tolerance grading, and optimized grease lubrication enables a high limiting speed of 22,000 rpm, suitable for demanding rotational applications.
Sealed and Pre-Lubricated for Longevity: The 2Z shields effectively retain the factory-applied grease and exclude contaminants. This creates a maintenance-free solution ideal for applications where re-lubrication is difficult, ensuring consistent performance over a wide temperature range from -30°C to 120°C.
Precision and Material Quality: Manufactured from high-grade chrome steel for both rings and balls, the bearing offers high durability and wear resistance. The CN radial internal clearance is the standard for normal operating conditions, ensuring optimal performance in a wide range of applications.
