CMAK equips its travel wheels with SKF brand 21000, 22000, and 23000 series bearings, offering superior load capacity and durability compared to the 6000 series bearings commonly used by competitors.
- Handles Lateral Loads – Unlike standard 6000 series bearings, CMAK’s bearings are specifically engineered to withstand lateral forces, ensuring safe, stable crane travel even under side stresses.
- Heavy-Duty Design – Available with 45 HRC surface hardness for extreme wear resistance.
- Flexible Mounting Options – Torque-arm or flanged connection configurations available for seamless integration.
This design choice means longer service life, fewer failures, and greater reliability — especially in high-capacity bridge and gantry crane applications where side forces are inevitable.
These components are the backbone of crane travel mechanisms in:
- Bridge cranes
- Gantry cranes
- Warehouse crane systems
- Ceiling cranes & underslung cranes
- Container handling systems
- Factory floor cranes
- Electric wire rope hoists
- Electric chain hoists
- Manual hoists and trolleys
- Single girder or double girder cranes
- Custom crane builds
