W 61700 X-2ZS Bearing Product Overview & Core Advantages
The W 61700 X-2ZS is a metric single row deep groove ball bearing designed for high performance in compact spaces. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantages include the ability to handle radial loads efficiently, a shielded design (2ZS) for contaminant protection, and pre-lubrication for maintenance-free operation. This makes it an ideal precision bearing for applications demanding reliability, compactness, and smooth operation.
Model Code Breakdown
- W: Indicates a stainless steel construction.
- 61700: The basic series designation for a metric, miniature deep groove ball bearing with a 10mm bore.
- X: Denotes a specific internal design or clearance not defined in standard nomenclature.
- 2ZS: Signifies that the bearing is shielded on both sides (2Z) with non-contact stainless steel shields (S), offering protection against contaminants while maintaining low friction and high-speed capability.
W 61700 X-2ZS Bearing Structural Features & Performance Benefits
Compact & Robust Design: With a minimal cross-section of 4mm width, this bearing is engineered for space-constrained applications without compromising structural integrity.
High Corrosion Resistance: The use of stainless steel for all critical components (rings, balls, cage) ensures long-term performance in harsh or wash-down environments.
Effective Sealing: The double-sided stainless steel shields (2ZS) effectively retain grease and exclude dust and other fine contaminants, enhancing bearing life.
Optimized for Smooth Operation: The deep groove raceway and precision-ground components facilitate quiet and smooth running, even at the specified limiting speed.
Maintenance-Free: Pre-lubricated with grease, the bearing is ready for immediate use and requires no relubrication, reducing total cost of ownership.
W 61700 X-2ZS Bearing Typical Application Areas
The W 61700 X-2ZS is suited for a wide range of precision instruments and small machinery, including:
- Small electric motors and gearboxes
- Medical and dental handpieces
- Precision optical instruments
- Office automation equipment (e.g., printers, scanners)
- Radio control models and drones
- Food processing equipment (where corrosion resistance is key)
