7228 BCBM – Angular contact ball bearings for smooth running and fast cycle times.
Quality that safeguards processes
This bearing design is intended for combined loads. Single-row versions primarily carry radial loads and axial forces in one direction; as a bearing pair, they handle both directions. The focus is on smooth running, high speed capability, reproducible results, and defined axial guidance.
Design and manufacturing quality
Axial stiffness is achieved through offset raceways and a defined contact angle (e.g., 15°/25°/40°). Precision-machined raceways reduce friction and stabilize running behavior. The cage guide is made of solid brass. Single-row bearings can be paired in O-, X-, or tandem configurations. In this configuration, the open design 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. Due to the limited angular adjustability, 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.
