Product Description
Built for large industrial equipment requiring high rigidity and
stable rotation.
Our 1797 series crossed roller bearings are widely used in cranes,
offshore machinery, rotary platforms, port equipment, tunnel
machines, and heavy-duty engineering systems.
This range includes:
1797/2460G2, 1797/2500G2, 1797/2600G2K, 1797/2635G2 and other
large-size models.
The crossed roller structure allows one bearing to support axial
load, radial load, and tilting moment simultaneously, helping
reduce installation space while improving rotational accuracy.
