61801-2RS1 Bearing Product Overview & Core Advantages
The 61801-2RS1 is a miniature deep groove ball bearing designed for compact applications requiring high reliability. As a metric single row bearing with integral seals (2RS1), it offers excellent protection against contamination. Its primary advantages include its small cross-section, ability to accommodate primarily radial loads, and long service life due to its sealed and pre-lubricated design. This bearing is engineered for applications where space is limited and operational reliability is critical.
61801-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61801 | Series designation for a miniature, extra-thin section deep groove ball bearing. |
| 2RS1 | Indicates contact seals made of Nitrile Rubber (NBR) on both sides. These seals provide effective protection against contaminants and retain lubricant. |
61801-2RS1 Bearing Structural Features & Performance Benefits
- Robust Sealing: The 2RS1 contact seals effectively shield the internal components from dust, moisture, and other contaminants, while also retaining the factory-applied grease, making the bearing suitable for demanding environments.
- High Precision & Rigidity: Manufactured to a P6 tolerance class, this bearing ensures precise running accuracy and consistent performance. The deep groove raceway and single-row design provide stable support for radial loads.
- Optimized Material Selection: The combination of chrome steel rings and balls with a stainless steel cage offers excellent durability, corrosion resistance, and reliable operation within a temperature range of -30°C to 120°C.
- Maintenance-Free Operation: Being pre-lubricated with grease and sealed, the bearing is ready for immediate use and requires no relubrication, reducing maintenance needs and total cost of ownership.
61801-2RS1 Bearing Typical Application Areas
- Small Electric Motors and Gear Motors
- Precision Instruments and Medical Devices
- Office Automation Equipment (e.g., Printers, Scanners)
- Computer Cooling Fans and Spindle Drives
- Robotics and Small Actuators
- Radio-Controlled Models and Drones
