WBB1-8706-2Z Bearing Product Overview & Core Advantages
The WBB1-8706-2Z is a single row deep groove ball bearing engineered for precision and reliability in compact applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to efficiently handle radial loads while its shielded design ensures long-term performance. This bearing is characterized by its compact dimensions (6mm bore, 12mm OD, 4mm width), making it an ideal solution for applications demanding high precision and space constraints.
WBB1-8706-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| WBB1-8706 | Basic bearing designation, indicating a specific series and size. |
| 2Z | Signifies that the bearing is equipped with shields on both sides. This provides effective protection against contamination while allowing for higher speeds compared to contact seals. |
WBB1-8706-2Z Bearing Structural Features & Performance Benefits
Robust Construction: The single row deep groove raceway and stainless steel construction (rings, balls, and cage) provide excellent durability and corrosion resistance, suitable for various environments.
Radial Load Capacity: Engineered to primarily support significant radial dynamic loads (91 lbf) and radial static loads (33 lbf), ensuring stable operation.
Shielded Protection: The non-contact 2Z shields retain grease and protect the internal components from dust and debris, contributing to a maintenance-free and long service life without significant speed penalties.
Precision and Speed: Manufactured to P0 tolerance class with a standard CN radial internal clearance, ensuring consistent performance. The limiting speed of 56,000 rpm is facilitated by the optimized design and pre-lubrication with grease.
WBB1-8706-2Z Bearing Typical Application Areas
This bearing is ideally suited for a wide range of compact and precision devices, including:
- Small Electric Motors and miniature gearboxes
- Precision Instruments and medical devices
- Office automation equipment such as printers and scanners
- Radio-controlled models and drones
- Various low-torque, high-speed machinery requiring corrosion-resistant bearings
