3313 ANR

3313 ANR – Angular contact ball bearings (double row) for limited installation space and defined stiffness.

Quality that safeguards processes
This bearing design is intended for combined loads. Double-row versions carry axial loads in both directions and simultaneously absorb radial forces. They compactly replace a bearing pair and save 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. The cage is constructed of sheet steel. Double-row designs combine the functions of a bearing pair in a compact form. In this design, the open construction maintains low friction and simplifies lubrication. The outer ring features a groove with a snap ring (NR) for positioning. Tolerances are within 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.
