INA Insert Ball Bearings (Y-Bearings) and Belt Tension Pulleys form a purpose-engineered ecosystem that eliminates alignment errors, reduces installation space by 40%, and extends belt life by 200%. This integrated approach solves critical challenges in power transmission systems:
Insert Bearings: Combine housing, sealing, and locking in one unit
Tension Pulleys: Auto-adjust belt tension to compensate for wear/stretch
Unified Advantage: Plug-and-play installation with zero shimming required
Engineering Breakthroughs
- Locking Security System
Eccentric Collar Physics:
1:15 taper ratio generates 850 MPa radial pressure
Zero-slip up to 600 Nm shaft torque
Anti-Vibration Design:
DynaGrip™ thread geometry prevents self-loosening
