W 61910 Bearing Product Overview & Core Advantages
The W 61910 is a metric single row deep groove ball bearing engineered for high-performance applications requiring precision and reliability. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its primary function is to support radial loads efficiently, making it a fundamental component for smooth rotational motion. The bearing features an open design and comes with a standard CN radial internal clearance, providing a versatile solution for a wide range of industrial settings. Its compact cross-section and compliance with ROHS and REACH standards make it a responsible and durable choice.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| W 61910 | Basic model number for a single row deep groove ball bearing with a 50mm bore. |
| Open (No Seal Suffix) | No seals or shields, allowing for higher speeds and custom lubrication. Requires a clean operating environment. |
| P0 Tolerance Class | Standard dimensional and geometrical tolerance per ISO standards. |
| CN Radial Clearance | Normal radial internal clearance, suitable for most common operating conditions. |
W 61910 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The rings, balls, and cage are manufactured from stainless steel, providing superior corrosion resistance and making the bearing ideal for applications exposed to moisture, chemicals, or wash-down environments.
- High-Speed Capability: The open design and optimized geometry contribute to a high limiting speed of 12,000 rpm, reducing friction and heat generation.
- Radial Load Capacity: The deep groove raceway and precision-ground components enable the bearing to handle significant radial dynamic and static loads (2810 lbf and 2608 lbf, respectively).
- Precision & Reliability: Manufactured to P0 tolerance class, this bearing ensures consistent performance, low noise, and long service life in precision assemblies.
- Versatile Lubrication: Supplied without grease (None), it allows for the application of specialized lubricants tailored to specific operational needs, such as high-temperature or food-grade requirements.
W 61910 Bearing Typical Application Areas
This single row ball bearing is widely used in various industries and equipment, including:
- Food and Beverage Processing Machinery
- Medical and Laboratory Equipment
- Chemical Processing Pumps and Mixers
- Agricultural Machinery
- Electric Motors and Small Gearboxes
