Common purchasing and maintenance references include 4.055 · MR0022 · JD70.1-44 · 400-0055 · TR070.0200.
Suffixes, seals, lubrication, OD variants and mounting plates can change fit. Send the complete marking and a controlled drawing for confirmation.
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
Forklift masts, pallet stackers, conveying frames and vertical lifting guides.
