Frequently Asked Questions
Q: What are the bore size and width specifications for SKU 00591-76004-81?
A: This bearing assembly has a 20mm bore diameter, 47mm outer diameter, and 14mm width. It is manufactured to ISO 6001 standards for electric lift truck mast roller applications.
Q: Which electric lift truck brands does this bearing assembly fit?
A: SKU 00591-76004-81 is compatible with Crown, Linde, and Yale electric lift trucks with comparable mast geometry. Cross-reference your equipment parts manual to confirm bearing pocket dimensions and mounting style.
Q: What material composition and load rating does this bearing assembly have?
A: The bearing assembly uses chrome-steel races with sealed rolling elements and a rated dynamic load capacity of 3.2 kN. This rating is sufficient for standard mast extension cycles on trucks rated up to 2500 kg capacity.
Q: How long does this bearing assembly last before replacement?
A: With proper greasing every 500 to 1000 operating hours, this bearing typically lasts 4 to 6 years. Lack of lubrication, dirt ingestion, or excessive shock loads can reduce service life to 1 to 2 years.
Q: What are signs of bearing wear or failure?
A: Noise during mast operation, rough rotation, excessive play in the mast rails, or visible grease leakage indicate bearing wear. Any of these symptoms requires immediate replacement to prevent mast derailment and safety hazards.
Q: Are there OEM cross-reference part numbers for this bearing assembly?
A: SKU 00591-76004-81 matches OEM specifications for Linde part L154702100 and equivalent Crown assemblies. Contact us with your truck serial number and we can confirm compatibility and provide OEM cross-references.
