Frequently Asked Questions
Q: What is the 90368-19037 tapered roller bearing cup?
A: The 90368-19037 is a precision tapered roller bearing cup used in manual pallet jack load wheel assemblies and Toyota axle systems. This component is the outer raceway of a tapered roller bearing set and must be paired with a matching cone assembly (90363-17050 or equivalent) for proper operation. The cup supports both radial and axial loads in pallet jack steering and drive wheel applications.
Q: What are the cross-reference and equivalent part numbers for 90368-19037?
A: The 90368-19037 is equivalent and interchangeable with LM11949/10 series bearing cups manufactured by FAG, FBJ, and Koyo. The part also supersedes IRB-IR2030 and Honda part number 91052-671-004. When ordering, confirm that the cone assembly part number matches your chosen cup reference. Cross-reference: Toyota 90368-19037, LM11949/10 (FAG, FBJ, Koyo).
Q: What is the material composition of the 90368-19037 bearing cup?
A: The 90368-19037 is manufactured from through-hardened ASTM-grade bearing steel. This alloy steel composition provides the hardness, wear resistance, and fatigue strength required for tapered roller bearing applications. The precision-ground raceway surface maintains dimensional accuracy and proper rolling element contact under load.
Q: Which pallet jack models use the 90368-19037 bearing cup?
A: The 90368-19037 is used in select Toyota manual pallet jack models as well as compatible Honda and aftermarket equipment using LM11949/10 bearing sets. Compatibility depends on axle design and load wheel diameter. Verify your equipment model, serial number, and current bearing cup part number before ordering to confirm fit.
Q: How long does the 90368-19037 bearing cup last in service?
A: Bearing cup lifespan depends on operational load, lubrication, and maintenance practices. Under normal warehouse use with proper lubrication and maintenance, a tapered roller bearing cup typically lasts 2-5 years. Failure signs include grinding noise, wheel drag, or visible spalling on the raceway. Inadequate lubrication and contamination accelerate wear and failure.
Q: Can I use the 90368-19037 cup with a non-matching cone assembly?
A: No. Tapered roller bearing cups and cones must be matched pairs for proper load distribution and alignment. Mixing cups and cones from different manufacturers or part numbers causes misalignment, edge loading, and rapid failure. Always replace cups and cones as matched sets. Verify the cone part number matches before installation.
