WBB1-8705 Bearing Product Overview & Core Advantages
The WBB1-8705 is a metric single row deep groove ball bearing engineered for precision applications requiring compact design and reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. This bearing is designed to primarily handle radial loads and is characterized by its high limiting speed and P0 tolerance class, making it a suitable choice for high-precision, high-reliability scenarios where consistent performance is critical.
WBB1-8705 Bearing Model Code Explained, Specifications & Naming Convention
- WBB1-8705: Base model number indicating specific bearing dimensions (5mm bore, 10mm OD, 3mm width).
- Seal Type: Open: The bearing is supplied without seals or shields, allowing for maximum speed capability and easy relubrication if necessary.
- Lubrication: None: The bearing is supplied without grease, providing flexibility for the user to apply a specialized lubricant suited for the specific application environment.
- Radial Internal Clearance: CN: Standard (normal) radial internal clearance.
- Tolerance Class: P0: Standard dimensional and geometrical tolerance per ISO standards.
WBB1-8705 Bearing Structural Features & Performance Benefits
The single row deep groove construction provides a versatile and robust solution. The raceways are precision-ground to facilitate smooth operation and minimize friction. The use of a stainless steel cage ensures compatibility with the rings and balls, contributing to the bearing's overall durability and corrosion resistance. The open design and optimized internal geometry are key factors enabling the high limiting speed of 85,000 rpm. The stainless steel construction of all components ensures reliable operation within a temperature range of -30°C to 120°C and makes the bearing suitable for demanding environments.
WBB1-8705 Bearing Typical Application Areas
This bearing's compact size, high-speed capability, and corrosion resistance make it ideal for a variety of precision instruments and small machinery, including:
- Small precision electric motors
- Medical and dental handpieces
- Optical encoders and scanners
- Instrumentation and control devices
- Small fans and pumps
