S699 2rs Bearing Product Overview & Core Advantages
The S699 2RS is a sealed single row deep groove ball bearing engineered for precision applications requiring reliable operation under radial loads. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its key advantages include a compact design, a radial dynamic load rating of 425 lbf, and the convenience of being pre-lubricated and sealed for life with nitrile rubber contact seals (2RS), making it a maintenance-free solution for a wide operating temperature range.
Model Code Breakdown
- S699: Basic model number denoting a metric, single row deep groove ball bearing with a 9mm bore.
- 2RS: Signifies that the bearing is equipped with two (2) Nitrile Rubber (RS) Contact Seals on both sides. This provides superior protection against contaminants and retains lubricant.
S699 2rs Bearing Structural Features & Performance Benefits
All-Stainless-Steel Construction: The bearing rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and durability in harsh environments, making it suitable for applications in food processing, medical equipment, and chemical exposure.
Deep Groove Raceway & High-Capacity Design: The deep, continuous raceways on both rings are optimized to support significant radial loads and moderate axial loads in both directions, ensuring stable performance.
Sealed and Pre-Lubricated for Life: The two Nitrile Rubber (NBR) contact seals (2RS) effectively shield the internal components from dust, moisture, and other contaminants while retaining the factory-applied grease. This creates a maintenance-free assembly with a long service life.
Precision and Speed: Manufactured to ABEC1 tolerance standards, this bearing ensures consistent running accuracy. With a limiting speed of 30,600 rpm, it is well-suited for high-speed applications such as small spindles and high-RPM motors.
S699 2rs Bearing Typical Application Areas
The S699 2RS is ideal for applications demanding corrosion resistance, high speed, and reliability. Common uses include:
- Precision instruments and optical devices
- Small electric motors and spindles
- Medical and dental handpieces
- Food and beverage processing machinery
- Office automation equipment (e.g., printers, scanners)
- Radio-controlled models and drones
