Frequently Asked Questions
Q: What type of bearing is the KO 301821-005?
A: The KO 301821-005 is a cylindrical roller bearing designed for manual pallet jack applications. This bearing type handles radial loads while maintaining low friction, critical for smooth pump and hydraulic valve operation in manual lift equipment.
Q: What manual pallet jack models is the KO 301821-005 compatible with?
A: The KO 301821-005 bearing is used in standard manual pallet jack assemblies across multiple OEM brands including Crown, Toyota, Yale, and Raymond. Verify equipment model and bearing bore diameter before ordering to confirm compatibility.
Q: What is the bearing cage material for KO 301821-005?
A: The KO 301821-005 uses a roller bearing cage designed to maintain roller spacing and alignment under load. The cage material is engineered to withstand repeated cycling in manual pallet jack pump and valve assemblies without excessive wear.
Q: How long does the KO 301821-005 bearing typically last?
A: Bearing lifespan depends on load frequency and maintenance. In normal warehouse manual pallet jack service, the KO 301821-005 lasts 2-4 years with regular oil lubrication. Insufficient lubrication or contamination accelerates wear and bearing failure.
Q: What are the symptoms of KO 301821-005 bearing failure?
A: Failed or failing KO 301821-005 bearings produce noise, grinding, or squealing during pump operation. Load raising becomes rough or jerky. Inspect for metal particles in hydraulic oil, a clear sign of bearing wear or internal damage.
