Key Features
● Stable inner ring structure
Fixed central rib on the inner ring effectively absorbs axial forces, maintaining stable operation under continuous vibration and avoiding axial displacement.
● Optimized cage performance
Precision-guided dual-direction cage keeps consistent internal clearance, reduces friction and wear, dampens shock and helps extend service life.
● Flexible bore choices
Available in cylindrical and tapered bores for easy installation and better compatibility with various vibrating machinery shafts.
Key Advantages
● Strong resistance to vibration and impact, suitable for vibrating screens, crushers and feeders
● High load and shock capacity to handle heavy repeated loads in mining and construction equipment
● Low friction and stable operating temperature, reducing overheating damage
● Longer service life and less frequent replacement
● Good adaptability to dusty, humid and heavy-duty working sites
