MF117 2rs Bearing Product Overview & Core Advantages
The MF117 2RS is a metric single row deep groove ball bearing designed for compact applications requiring reliable performance. This sealed bearing features a robust construction using chrome steel rings and balls, providing excellent durability. Its primary advantage lies in its ability to handle radial loads efficiently while its sealed design protects against contamination, making it suitable for applications demanding consistent operation and extended service life.
Model Code Breakdown
- MF117: Basic bearing series designation, indicating a specific size and internal design.
- 2RS: Signifies that the bearing is equipped with two rubber contact seals (RS), one on each side. This provides superior protection against dust, moisture, and other contaminants compared to non-contact shields.
MF117 2rs Bearing Structural Features & Performance Benefits
Compact and Robust Design: With a small cross-section (7mm bore, 11mm OD, 3mm width), this bearing is ideal for space-constrained assemblies. The use of chrome steel for rings and balls ensures high load capacity and wear resistance.
Effective Sealing: The 2RS rubber seals not only protect the internal components from contaminants but also effectively retain the lubricant, contributing to a longer service life and reduced maintenance needs.
Optimized Internal Geometry: Featuring 9 balls of 1.2mm diameter and a stainless steel cage, the bearing maintains stable operation and can achieve a limiting speed of 43,000 rpm under proper lubrication conditions.
Standardized Quality: Manufactured to ABEC1 tolerance class with an MC3 radial internal clearance (0.002mm to 0.013mm), ensuring consistent performance and interchangeability.
MF117 2rs Bearing Typical Application Areas
This bearing is commonly used in:
- Small Electric Motors (e.g., in consumer electronics, power tools)
- Precision Instruments and gauges
- Office Automation Equipment (printers, scanners)
- Medical Devices requiring compact, reliable rotary support
- Light-duty gearboxes and pumps
