WBB1-8706 R-2RS1 Bearing Product Overview & Core Advantages
The WBB1-8706 R-2RS1 is a metric single row deep groove ball bearing designed for compact applications requiring high reliability. Its core advantages stem from its sealed construction and stainless steel components, making it suitable for environments demanding corrosion resistance. This bearing is engineered to primarily handle radial loads efficiently while offering robust performance within its specified speed and temperature ranges. Its pre-lubricated and sealed design ensures long-term, maintenance-free operation, which is critical for applications where service access is limited.
Model Code Breakdown
- WBB1-8706: Manufacturer's base model/series designation.
- R: Typically denotes a flanged outer ring, providing ease of mounting and axial location.
- 2RS1: Indicates the bearing is fitted with two contact seals (one on each side). The "RS1" suffix specifies low-friction, synthetic rubber seals that provide effective protection against contaminants and retain lubricant.
WBB1-8706 R-2RS1 Bearing Structural Features & Performance Benefits
Robust Sealed Design: The dual RS1 contact seals effectively shield the internal components from dust, moisture, and other contaminants, while securely retaining the factory-applied grease. This significantly enhances bearing life in challenging conditions.
Corrosion Resistance: Manufactured entirely from stainless steel (rings, balls, and cage), this bearing offers excellent resistance to rust and corrosion, ideal for food processing, medical, and chemical environments or where wash-downs are common.
Compact and Lightweight: With a 4 mm width0.0018 kg, it is an ideal solution for space-constrained and weight-sensitive applications.
Simplified Mounting: The integrated flange on the outer ring simplifies axial positioning and mounting within a housing, reducing assembly time and cost.
WBB1-8706 R-2RS1 Bearing Typical Application Areas
The WBB1-8706 R-2RS1 is well-suited for a variety of compact and precision mechanisms, including:
- Small Electric Motors (e.g., miniature DC motors, stepper motors)
- Medical and Dental Handpieces
- Office Automation Equipment (printers, scanners, copiers)
- Instrumentation and Precision Gearboxes
- Food and Beverage Processing Equipment
