Execution guidance
Standard design and inspection
Design function
A fixed axial roller supports combined radial and side load in a compact mast-guide envelope.
Installation and adjustment
Set running clearance through the mating profile and mounting position; the axial roller itself is not eccentric-adjustable.
Inspection focus
Verify radial OD, overall height, axial-roller position, stud geometry and smooth rotation.
Application
Application and RFQ checklist
Material-handling masts, lifting columns, AS/RS systems and steel guide profiles.
Information required for selection
