3311 ATN9/C3 – Angular contact ball bearing (double row) for high system stiffness with axial mounting on both sides.
Quality that safeguards processes
Angular contact ball bearings reliably transmit combined loads. Double-row designs carry axial loads in both directions while simultaneously absorbing radial forces. They compactly replace a bearing pair, saving installation space. The focus is on smooth running, high speed capability, reproducible results, and defined axial guidance.
Design and manufacturing quality
In each row, staggered raceways and a defined contact angle ensure axial stiffness. Finely machined raceways reduce friction and promote smooth running. The cage is made of fiber-reinforced polyamide. Double-row designs combine the function of a bearing pair in a compact form. Depending on the requirements, the open design remains low-friction and simplifies lubrication. The outer ring features a groove with a snap ring (NR) for axial stops. Dimensional accuracy corresponds to tolerance class Normal (P0). Angular adjustability is limited; precise alignment is recommended.
Convincing in everyday life
In everyday use, this results in smooth running, consistent temperature and vibration levels, and predictable quality even with frequent start/stop cycles and high cutting data. Other bearing designs are better suited for purely radial heavy loads.
Summary
Conclusion: speed-resistant, axially guiding and dimensionally stable – for stable processes and reliable results.
