Frequently Asked Questions
Q: What are the specifications for the YL 754959401-A tandem load wheel assembly?
A: The YL 754959401-A is a tandem (dual-wheel) load wheel assembly with polyurethane tread bonded to cast iron core. Tread hardness is 95 Shore A. The wheel diameter ranges 3.25 to 3.94 inches, width 3 to 3.5 inches, with 0.78 inch bore diameter. Includes steel axle with zinc plated finish and precision shielded ball bearings.
Q: What is the load capacity of the YL 754959401-A?
A: The YL 754959401-A is rated for a 2500 lbs load at 24 inch center. This is the combined capacity for the tandem wheel assembly as a unit. The dual-wheel design distributes load evenly across both wheels for reduced per-wheel stress during operations.
Q: How does the YL 754959401-A differ from the standard YL 754959401?
A: The YL 754959401-A features 95 Shore A polyurethane hardness, while the non-A version is 93A. The -A variant provides a slightly harder tread compound for increased durability in demanding applications. Both are tandem configurations for Yale electric pallet trucks. Verify your equipment manual to confirm which hardness specification is required.
Q: What core material and construction is used in the YL 754959401-A?
A: The YL 754959401-A features a cast iron core with polyurethane tread bonded to the machined surface. Cast iron provides strength and precision fit. The steel axle has a zinc plated finish for corrosion resistance. Precision shielded ball bearings reduce friction and extend service life.
Q: Is the YL 754959401-A suitable for cold storage or wet floor operations?
A: The YL 754959401-A features standard 95A polyurethane. For cold storage environments below freezing or sustained wet floor operations, verify tread grip performance with your Yale equipment manufacturer. Cold temperatures may reduce polyurethane flexibility. Alternative wheel specifications may be recommended for extreme environments.
Q: What bearing type is included in the YL 754959401-A assembly?
A: The YL 754959401-A includes precision shielded ball bearings integrated into the tandem wheel assembly. Shielded construction protects the bearing race from floor contamination. Bearings require periodic lubrication during equipment operation. Check for axle play and unusual noise as indicators of bearing wear.
