How Does SFR3 Bearing Reduce Friction?
SFR3 Bearing uses stainless steel balls and rings, which help minimise friction during operation.
Its precision design with seven balls ensures smooth rotation, even at high speeds up to 38,700 rpm.
The open seal type allows for easy lubrication, further reducing friction and wear.
With a radial clearance of 0.00008″ to 0.0005″, it maintains consistent performance in various applications.
Common Applications of SFR3 Bearing
SFR3 Bearing works well in small machinery, like dental drills or camera mechanisms, where its compact size and stainless steel build handle light radial loads smoothly. The open design simplifies lubrication, keeping maintenance straightforward.
Industrial Uses of SFR3 Bearing
In automation systems, SFR3 Bearing fits neatly into robotic arms or conveyor guides, thanks to its flanged outer ring for secure mounting. Its ABEC1 tolerance ensures reliable performance without overcomplicating assembly.
Where Is SFR3 Bearing Used?
You’ll often spot SFR3 Bearing in hobbyist projects, such as RC cars or 3D printers, where precision and corrosion resistance matter. The lightweight design (just 2.5g) won’t bog down delicate movements.
Built for Versatility: SFR3 Bearing
From lab equipment to small fans, SFR3 Bearing’s wide temperature range (-86 to 230°F) handles varied environments. The stainless steel balls and rings resist wear, even with frequent use.
Light-Duty vs Heavy-Duty: Best Uses for SFR3 Bearing
While SFR3 Bearing excels in low-force applications like optical devices, it’s not suited for heavy machinery. Its 224 lbf dynamic load rating makes it ideal for precision over brute strength.
