6305-2Z/C3HT Bearing Product Overview & Core Advantages
The 6305-2Z/C3 is a metric single row deep groove ball bearing engineered for reliable performance in demanding applications. This shielded bearing excels in handling significant radial loads while offering protection from contamination. Its C3 radial internal clearance makes it particularly suitable for applications involving thermal expansion or where interference fits are used, ensuring stable operation across a wide temperature range. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides a cost-effective solution for general industrial use where precision and durability are paramount.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6305 | Standard deep groove ball bearing series with 25mm bore, 62mm OD, 17mm width |
| 2Z | Shielded on both sides providing effective protection against contaminants while maintaining low friction |
| C3 | Greater than normal radial internal clearance for applications with thermal expansion or interference fits |
6305-2Z/C3HT Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured entirely from chrome steel for rings, balls, and cage, ensuring consistent material properties and enhanced durability under radial dynamic loads up to 4631 lbf.
Contamination Protection: The double-shielded (2Z) design effectively excludes dust and other particles while allowing for higher limiting speeds compared to contact seals, reaching 11,000 rpm.
Thermal Compensation: The C3 clearance accommodates dimensional changes due to temperature variations or press fits, preventing premature failure from excessive preload.
Maintenance-Friendly: The shielded design helps retain lubricant and excludes contaminants, extending service intervals in appropriate applications.
