BTW 75 CTN9/SP – Axial angular contact ball bearing (double-sided) for symmetrical axial mounting of tool spindles
Quality that safeguards processes
The double-acting design transmits axial loads in both directions with high rigidity and remains speed-stable. Thanks to the carefully optimized ball/raceway geometry, it runs smoothly and positions precisely. Limited radial load components can be absorbed; however, larger radial forces are generally transmitted separately.
Design and manufacturing quality
The design incorporates offset raceways with a large contact angle (e.g., 60°) to ensure axial stiffness. Simultaneously, a defined cage guide and finely machined raceways keep friction low. The double-acting unit forms a compact, double-sided guide without a second bearing, thus saving installation space. Since the angular adjustability is limited, precise contact surfaces for the shaft and housing are essential.
Convincing in everyday life
In operation, the rigid, double-sided guide ensures reproducible quality even with high cutting data and frequent start/stop cycles, while maintaining stable temperature and vibration levels. This results in predictable processes with a compact design.
Summary
In short: axially strong, speed-resistant and repeatable – for stable processes in precision drives.
