Frequently Asked Questions
Q: What Yale lift trucks or pallet jacks use the YL 27078800 bearing?
A: The YL 27078800 bearing is specified for Yale material handling equipment load-bearing assemblies. Application may include caster assemblies, wheel hubs, or mast roller systems. Verify your equipment model and application location before ordering.
Q: What are the bore diameter, outer diameter, and width dimensions?
A: Contact us with your equipment model or assembly location for exact bore size, OD, width, and internal clearance class. Using an oversized or undersized bearing will cause premature failure and may damage the mounting assembly.
Q: What bearing type is this: ball bearing, roller bearing, or needle bearing?
A: Confirm bearing type and internal design with us based on your specific Yale assembly. Different bearing types handle radial and axial loads differently. The wrong bearing type will fail quickly under equipment loads.
Q: What is the typical service life and what causes premature bearing failure?
A: Bearing life depends on load cycle, speed, lubrication, and alignment. Improper sealing, contamination, lack of grease, misalignment, and overload cause premature wear. Replace bearings showing noise, vibration, or rough rotation.
Q: What does this bearing need for maintenance?
A: Most Yale truck bearings require periodic grease lubrication. Check your equipment manual for grease type, relubrication intervals, and purge procedures. Over-greasing and under-greasing both reduce bearing life.
Q: Are there cross-reference bearing numbers from other manufacturers?
A: The YL 27078800 is the Yale OEM part number. Equivalent bearings from SKF, FAG, NTN, or Timken may be available if dimensions and load ratings match exactly. We recommend OEM or OEM-equivalent bearings for critical load-bearing applications.
