Execution guidance
High load axial support design and inspection
Design function
A separate hardened axial support carries higher side load than the compact standard arrangement.
Installation and adjustment
Confirm support orientation, available structural clearance and the specified washer or mounting arrangement.
Inspection focus
Inspect the hardened support, contact face, axial position, washer stack and both load paths.
Application
Application and RFQ checklist
Heavy steel handling, large lifting columns, crane guides and severe-duty linear guide structures.
