3311-BD-XL-2Z – double-row angular contact ball bearing for smooth running under cutting data load
Quality that safeguards processes
Double-row angular contact ball bearings are designed for combined loads and transmit axial forces in both directions. The two rows of balls create a compact alternative to paired single-row bearings, offering smooth running, high speed capability, and reproducible results with defined axial guidance.
Design and manufacturing quality
The double-row geometry with staggered raceways and a defined contact angle concentrates rigidity in a compact installation space and replaces a bearing pair. Precise cage guidance, finely machined raceways, and low friction contribute to smooth running. Double-sided shields (2Z) reduce particle ingress and improve lubricant retention with low friction. Furthermore, a precisely guided cage facilitates assembly. Accurate alignment is essential; the angular adjustability is limited by the design.
Convincing in everyday life
In everyday operation, this results in a clearly defined stiffness and a consistent temperature and vibration level – even with frequent start/stop cycles and increased cutting data. For predominantly radial heavy loads, other bearing designs are the more suitable option.
Summary
Speed-resistant, axially guiding and dimensionally stable – for stable processes and reliable results.
