Frequently Asked Questions
Q: What are the dimensions of the YL 055076400 bearing cup?
A: The YL 055076400 tapered roller bearing cup has an outer diameter of 59.15 mm, inner diameter of 48.65 mm, and width of 11.82 mm. These precision dimensions are critical for proper steer axle and drive unit assembly fit.
Q: Which Yale electric truck models use the YL 055076400?
A: The YL 055076400 is compatible with Yale MPW050EC802, ERC040RG, ERC040ZG, ERC050RG, ERC050ZG, ERC060RG, ERC060ZG, ERC065RG, ERC065ZG, MPW045EB802, MPB040EB827, MPB045EB827, MP040AC, and MPB040AC models. Verify your exact model number before ordering.
Q: What superseded part numbers does the YL 055076400 replace?
A: The YL 055076400 replaces and supersedes part number 0550764-00. When ordering replacement bearing cups, reference the YL 055076400 SKU to ensure you receive the correct current production part.
Q: Why is the YL 055076400 designed for steer axle applications?
A: Steer axle bearing cups experience combined radial and significant axial loads during turning and load shifts. The YL 055076400 tapered design and precision tolerances distribute these loads evenly across the race, improving stability, reducing wear, and extending steer mechanism lifespan.
Q: How should the YL 055076400 be maintained?
A: Bearing cups should be replaced when paired with new cone assemblies using proper bearing preload procedures. Regular greasing of the bearing assembly and inspection for play or noise are essential. Replace immediately if corrosion, spalling, or race damage is detected.
Q: What is the expected service life of the YL 055076400 bearing cup?
A: In normal material handling service, the YL 055076400 typically lasts 3000 to 10000 operating hours. Steer axle bearing cups wear faster than fixed wheel bearings due to increased loading during turns. Proper lubrication, load management, and timely cone replacement extend cup life.
