R12ZZST-H566 Bearing Product Overview & Core Advantages
The R12ZZST-H566 is a precision shielded single row deep groove ball bearing designed for reliable performance in demanding applications. Engineered with inch dimensions, this bearing excels in handling radial loads while offering stable operation across a wide temperature range. Its shielded design provides essential contamination protection, and manufactured to ABEC 1 precision class, it delivers consistent performance for general industrial use where cost-effectiveness and reliability are paramount.
Model Code Breakdown
- R12: Basic series designation, inch size bearing
- ZZ: Double shielded on both sides for enhanced contaminant exclusion
- S: Indicates special internal design or clearance
- T: Denotes specific cage type/material (typically phenolic/polyamide)
- H566: Manufacturer's specific suffix, may indicate special heat treatment, lubrication, or other proprietary features
R12ZZST-H566 Bearing Structural Features & Performance Benefits
This bearing's single row deep groove construction provides excellent radial load capacity while maintaining compact dimensions. The double shielded (ZZ) design effectively protects the internal components from dust and debris, extending service life in contaminated environments. The phenolic cage (T) contributes to smooth operation at moderate speeds and is suitable for the specified temperature range. Manufactured from chrome steel for both rings and balls, the bearing offers good wear resistance and durability. The CN radial internal clearance is standard for normal operating conditions, ensuring proper fit and function in most applications.
