Frequently Asked Questions
Q: What is the CL 746624 Roller Column and what does it do?
A: The CL 746624 Roller Column is an OEM mast guide bearing assembly for Clark electric lift truck mast systems. It ensures precise alignment and smooth vertical mast movement while handling high lateral and axial loads during lifting and lowering cycles.
Q: Which Clark electric lift truck models use the CL 746624 Roller Column?
A: The CL 746624 is compatible with Clark electric lift truck models that utilize this part number in their mast assembly. Verify your truck model, serial number range, and mast configuration before ordering to confirm compatibility.
Q: What are the precision specifications for the CL 746624 bearing surface?
A: The CL 746624 bearing surface is ground to precision tolerance with a roughness average (Ra) of 0.8 micrometers. This tight tolerance ensures proper mast column guidance and minimizes side-sway during load handling.
Q: What symptoms indicate the CL 746624 Roller Column needs replacement?
A: Replace the roller column if the mast exhibits excessive side-sway, binding during extension, grinding or squealing noises, or visible wear on the bearing surface. These symptoms reduce load safety and mast control.
Q: How does the CL 746624 Roller Column maintain mast alignment?
A: The roller column uses precision-ground bearing surfaces to guide the mast column vertically while constraining lateral movement. High-load capacity design distributes wear evenly across multiple contact points for extended service life.
Q: Can the CL 746624 be cross-referenced to mast bearings from other manufacturers?
A: The CL 746624 is a Clark-specific OEM component. While equivalent mast guide bearings exist for Toyota, Raymond, Yale, Hyster, and Jungheinrich electric lift trucks, dimensions and specifications vary. Verify exact fitment before substituting with aftermarket alternatives.
