SFR168 Bearing Product Overview & Core Advantages
The SFR168 is a precision-engineered single row ball bearing designed for demanding applications requiring reliable performance in compact spaces. Manufactured entirely from stainless steel, this bearing offers excellent corrosion resistance and is suitable for a wide operating temperature range. Its open design allows for versatile lubrication options, while its ABEC1 precision class ensures consistent and smooth operation. The SFR168 is engineered to handle primarily radial loads efficiently, making it an ideal choice for applications where space is limited but performance cannot be compromised.
SFR168 Bearing Model Code Explained, Specifications & Naming Convention
The model designation SFR168 follows a standard industry format. While "SFR" typically denotes the series, the numerical code provides key dimensional information:
- SFR168: Series identifier for a specific family of miniature and instrument bearings.
- Bore Diameter: 0.25 inch (1/4")
- Outside Diameter: 0.375 inch (3/8")
- Width: 0.125 inch (1/8")
SFR168 Bearing Structural Features & Performance Benefits
- All-Stainless Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and durability, ideal for harsh environments and clean applications.
- Optimized Internal Geometry: With 11 precision balls of 0.03941" diameter, the bearing achieves a balanced load distribution, contributing to smooth rotation and a high limiting speed of 43,200 rpm.
- Precision Performance: Manufactured to ABEC1 tolerance class and MC3 radial internal clearance (0.00008" to 0.0005"), ensuring reliable, low-vibration, and low-noise operation.
- Robust Load Capacity: Engineered to support a dynamic load rating of 64 lbf and a static load rating of 28 lbf, providing dependable performance under radial stresses.
- Wide Temperature Range: Operates effectively from -86°F to 230°F, accommodating various operational environments.
SFR168 Bearing Typical Application Areas
The SFR168 is ideally suited for applications requiring compact, high-speed, and corrosion-resistant bearings. Key industries and equipment include:
- Precision Instruments: Optical encoders, medical devices, and laboratory equipment.
- Small Motors and Gearboxes: Stepper motors, servo motors, and miniature DC motors.
- Office Automation Equipment: Printers, scanners, and copiers.
- Robotics and Automation: Small robotic joints, conveyor belt guides, and positioning systems.
- Aerospace and Defense: Guidance systems, instrumentation, and control surfaces where reliability and weight are critical.
