3311 A-2Z/C3MT33 – Angular contact ball bearing (double row) for high system stiffness with axial mounting on both sides.
Quality that safeguards processes
As bearings for combined loads, angular contact ball bearings offer defined guidance. Double-row designs guide 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
Offset raceways in each row with a defined contact angle enhance axial stiffness. Precision-machined raceways reduce friction and promote smooth running. Furthermore, the cage is made of sheet steel. Double-row versions combine the function of a bearing pair in a compact design. Depending on the application, the 2Z version with protective discs on both sides shields against coarse contaminants. For mounting, the outer ring features a groove with a snap ring (NR). Manufacturing is designed to tolerance class P0. Angular adjustability is limited; precise alignment is recommended.
Convincing in everyday life
In operation, this translates into defined stiffness, 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
In short: speed-resistant, axially guiding and dimensionally stable – for stable processes and reliable results.
