How Does SFR4 Bearing Reduce Friction?
SFR4 Bearing features stainless steel rings and balls, ensuring smooth operation with minimal friction.
Its precision design includes eight balls for even load distribution, enhancing performance in radial applications.
The ABEC1 tolerance class ensures consistent quality, while the MC3 radial clearance allows for optimal movement.
With a maximum speed of 34,200 rpm, SFR4 Bearing is suitable for high-speed miniature applications.
The flanged design provides secure mounting, reducing misalignment risks during operation.
Its temperature range of -86 to 230°F makes it adaptable to various environmental conditions.
Common Applications of SFR4 Bearing
SFR4 Bearing works well in small machinery, especially where space is tight, like in compact fans or miniature motors. Its stainless steel build keeps it rust-free, even in damp conditions.
What Makes SFR4 Bearing a Preferred Choice?
With its flanged design, SFR4 Bearing stays securely in place, making it great for lightweight robotics or small conveyor systems. The open seal allows for easy lubrication, extending its lifespan.
Built for Versatility: SFR4 Bearing
You’ll often spot SFR4 Bearing in medical devices like handheld surgical tools, where precision and hygiene matter. The inch sizing fits neatly into many North American and UK-made instruments.
Light-Duty vs Heavy-Duty: Best Uses for SFR4 Bearing
While SFR4 Bearing handles light loads in office printers smoothly, it’s also reliable in delicate lab equipment. The ABEC1 tolerance ensures consistent performance without overcomplicating maintenance.
