W 61706 R Bearing Product Overview & Core Advantages
The W 61706 R is a metric single row deep groove ball bearing engineered for precision radial load applications. Manufactured entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its compact design, with a minimal 4 mm width, makes it ideal for space-constrained assemblies requiring high reliability and smooth operation. The bearing features an open design and comes with a standard CN radial internal clearance, suitable for a wide operating temperature range.
W 61706 R Bearing Model Code Explained, Specifications & Naming Convention
The model number W 61706 R can be broken down as follows:
- W: Designates a series of stainless steel deep groove ball bearings.
- 61706: The specific size designation, indicating a 30 mm bore and 37 mm outside diameter.
- R: Signifies the use of a snap ring (also known as a retaining ring) on the outer ring. This feature allows for simplified axial location within a housing.
W 61706 R Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a cross-section of only 4 mm and a weight of just 0.0085 kg, this bearing is perfect for applications where size and weight are critical factors.
- High Corrosion Resistance: The all-stainless-steel construction ensures reliable performance in harsh environments and is compliant with ROHS and REACH directives.
- Simplified Assembly: The integrated snap ring on the outer ring facilitates easy installation and secure axial positioning, reducing the need for complex housing designs.
- Precision Performance: Manufactured to P0 tolerance class with tight bore and outside diameter tolerances, ensuring consistent and accurate performance in precision mechanisms.
W 61706 R Bearing Typical Application Areas
This bearing is commonly used in:
- Small electric motors and gearboxes
- Medical and dental equipment
- Food processing machinery
- Precision instruments and optical devices
- Office automation equipment (e.g., printers, scanners)
