Frequently Asked Questions
Q: What is the HY 3003676 roller column and which trucks use it?
A: The HY 3003676 is an OEM roller column for Hyster electric lift truck masts. It is designed for high-capacity truck mast guide channels and includes a sealed deep-groove bearing with hardened steel construction. This component is compatible with Hyster H300XD, H330XD, H360XD, and H210XD48 series trucks. Verify compatibility by confirming your truck serial number and mast type match these model designations.
Q: What are the exact dimensions of the HY 3003676 roller column?
A: The HY 3003676 has a bore of 1.25 inches and an outer diameter of 3.50 inches. These dimensions are critical for proper fitment in the mast channel. Confirm these measurements match your mast before ordering, as similar-looking rollers from other manufacturers or series may have different bore and outer diameter combinations.
Q: What material and hardness does the HY 3003676 roller column have?
A: The HY 3003676 is manufactured from machined alloy steel with a hardened raceway minimum Rockwell hardness of C45. This hardness specification ensures the raceway resists indentation and spalling under the concentrated contact stresses from the mast channel guide surfaces. The hardened construction extends service life in high-capacity lift applications.
Q: How long does the HY 3003676 roller column typically last?
A: Under normal warehouse duty (30 to 50 lift cycles per hour), the HY 3003676 sealed bearing typically lasts 3 to 5 years before replacement is needed. Lifespan depends on load capacity utilization, mast extension frequency, and environmental conditions. Failure is indicated by grinding noise, binding mast movement, or visible debris in the mast channel.
Q: Is the HY 3003676 bearing sealed and what is the maintenance requirement?
A: The HY 3003676 includes a sealed deep-groove bearing that requires no field lubrication. The sealed design protects against warehouse dust and hydraulic mist. If bearing noise develops or the roller does not spin freely, replace the entire roller column assembly. Do not attempt to disassemble, clean, or relubricate the sealed bearing unit.
Q: What is the difference between the HY 3003675 and HY 3003676 roller columns?
A: The HY 3003676 is a variant of the HY 3003675 with identical bore (1.25 inch) and outer diameter (3.50 inch) dimensions. Differences may include bearing type, hardness specification, or manufacturing tolerance. Always verify the exact SKU required for your truck model and mast class. Do not interchange without confirming dimensional and bearing compatibility.
