6307-Z Bearing Product Overview & Core Advantages
The 6307-Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This precision bearing features integral shielded protection (Z-type) on both sides, effectively containing grease and excluding contaminants. Engineered to primarily handle radial loads, it also accommodates moderate axial loads in both directions. Its high-rigidity construction, combined with a P6 tolerance class and CN radial clearance, ensures reliable operation, high rotational accuracy, and long service life, making it an ideal choice for applications requiring dependable performance.
6307-Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6307 | Standard designation for a medium series deep groove ball bearing with a 35mm bore and 80mm outside diameter. |
| -Z | Signifies the bearing is equipped with a non-contact steel shield on one side. This shield retains lubricant and protects against large contaminants without significantly increasing friction. |
6307-Z Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel rings and balls with a stainless steel cage, this bearing offers a high radial dynamic load rating of 7891 lbf and a radial static load rating of 4271 lbf, ensuring durability under significant stress.
- Precision & High-Speed Capability: The P6 tolerance class provides superior dimensional accuracy and running precision, which is critical for smooth operation. Combined with the optimized design, it achieves a limiting speed of 12,000 rpm.
- Effective Sealing & Lubrication: The Z-shield effectively seals the bearing, retaining the pre-applied grease lubricant and protecting the internal components from dust and debris, contributing to a maintenance-free service life.
- Wide Operating Range: With a specified temperature range of -30°C to 120°C, this bearing is suitable for use in various environmental conditions.
