Frequently Asked Questions
Q: What material is the HY 87905 Roller Column made from?
A: The HY 87905 Roller Column is precision-machined from SAE 1045 steel and induction hardened with a black oxide finish for corrosion resistance and extended durability in continuous mast guide duty.
Q: Which Hyster electric lift truck models use the HY 87905 roller column?
A: The HY 87905 is compatible with multiple Hyster electric lift truck models. Verify your mast assembly configuration and model number before ordering to confirm fitment.
Q: What are the cross-reference and superseded part numbers for the HY 87905?
A: The HY 87905 supersedes Hyster part numbers 4080650, 4055608, 320344, and replaces 1395172 and 1333649. It also cross-references to 4080649, 1395174, 1333396, 1343010, and 1336088 across different Hyster models and service bulletins.
Q: What bearing type and construction does the HY 87905 use?
A: The HY 87905 incorporates a sealed radial bearing engineered for continuous mast guide duty, providing smooth roller operation while protecting against contamination and reducing maintenance requirements.
Q: How long does the HY 87905 roller column typically last in service?
A: The HY 87905 is engineered for extended industrial duty. Lifespan depends on duty cycle intensity, load handling frequency, preventive maintenance, and environmental conditions. Sealed bearing construction reduces wear and extends service life compared to older open designs.
Q: What is the surface finish and corrosion resistance of the HY 87905?
A: The HY 87905 has a black oxide finish applied after induction hardening, providing corrosion resistance and protecting the SAE 1045 steel against rust and surface degradation in indoor and outdoor warehouse environments.
