6211-2Z/W64 Bearing Product Overview & Core Advantages
The 6211-2Z/W64 is a metric single row deep groove ball bearing designed for exceptional reliability in demanding applications. Its key advantage lies in the combination of shielded protection (2Z) and factory-preloaded Soild Oil lubrication (W64), creating a robust, maintenance-free solution. This configuration delivers high operational consistency, excellent radial load capacity, and reliable performance across a wide temperature range, making it ideal for applications where re-lubrication is difficult or undesirable.
6211-2Z/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
| 6211 | Basic bearing designation: 55mm bore, 100mm OD, 21mm width | Defines standard bearing dimensions for interchangeability. |
| 2Z | Non-contact steel shields on both sides | Provides effective contamination protection with minimal impact on limiting speed. |
| W64 | Pre-greased with Soild Oil polymer-based lubricant | Ensures long-term lubrication, eliminates leakage, and enables maintenance-free operation. |
6211-2Z/W64 Bearing Structural Features & Performance Benefits
Deep Groove Raceway & Single Row Design: Optimized for high radial dynamic load rating (9757 lbf) and moderate axial loads in both directions, providing versatile load-handling capability.
Shielded Construction (2Z): Steel shields protect the internal components from dust and debris while maintaining low friction, contributing to the high limiting speed of 6,300 rpm.
Soild Oil Lubrication (W64): This solid polymer lubricant is permanently integrated, preventing oil leakage and ensuring consistent performance. It is suitable for the specified temperature range of -30°C to 120°C.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance class with standard radial internal clearance (CN), ensuring smooth operation and reliable performance in general industrial applications.
