D/W R6 R-2Z Bearing Product Overview & Core Advantages
The D/W R6 R-2Z is a single row deep groove ball bearing designed for high precision and reliable performance in demanding applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to handle radial loads efficiently while its shielded design (2Z) retains factory-applied grease and protects against contaminant ingress. This combination makes it a compact, durable, and low-maintenance solution for applications requiring long service life and consistent operation.
D/W R6 R-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| D/W R6 | Basic Bearing Designation | Specifies a single row, deep groove ball bearing with a 0.375" bore and standard dimensions. |
| R- | Flange Design | Indicates the bearing is equipped with an outer ring flange, facilitating simplified mounting and alignment. |
| 2Z | Seal Type | Signifies non-contact shields on both sides, offering effective protection against contaminants while minimizing friction for higher limiting speeds. |
D/W R6 R-2Z Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All components, including rings, balls, and cage, are manufactured from stainless steel, providing superior corrosion resistance and durability in harsh environments.
- Deep Groove Raceway: The geometry of the deep groove raceway is optimized to support significant radial dynamic load ratings (555 lbf) and accommodate minor misalignments.
- Flanged Outer Ring: The integrated flange (Flange outer diameter: 0.96902") allows for easy and secure axial location, simplifying housing design and bearing installation.
- Shielded & Pre-Lubricated: The 2Z shields retain the factory-applied grease, protecting the bearing from dust and debris. This creates a maintenance-free system ideal for sealed-for-life applications, operating within a temperature range of -30° to 120 °C.
- Precision Tolerances: Manufactured to P0 tolerance class and standard radial internal clearance (CN), ensuring smooth, quiet, and reliable operation.
D/W R6 R-2Z Bearing Typical Application Areas
This bearing is ideally suited for a wide range of applications where compact size, corrosion resistance, and reliable performance are critical. Key sectors include:
- Food & Beverage Processing Equipment (conveyors, mixers)
- Medical and Laboratory Devices
- Precision Instruments and Optical Equipment
- Small Electric Motors and Gearboxes
- Agricultural and Marine Equipment (in non-submerged, corrosive atmospheres)
