Frequently Asked Questions
Q: What is the MU 51071189 support wheel?
A: The MU 51071189 is a support wheel assembly for Multiton electric and manual pallet trucks. It features a polyurethane tread, ball bearing, and either steel or nylon core depending on model configuration.
Q: Which Multiton models are compatible with the MU 51071189?
A: The MU 51071189 support wheel fits Multiton M, J, TM, and TM55 series pallet trucks. These models span both electric lift and manual pallet jack platforms used in warehouse and industrial applications.
Q: What is the difference between nylon and steel cores?
A: The MU 51071189 may have either nylon or steel core depending on model year and truck configuration. Nylon cores are lighter and corrosion-resistant; steel cores offer higher load capacity. Verify your equipment specifications to confirm which version your truck requires.
Q: What is the purpose of the ball bearing in the MU 51071189?
A: The ball bearing allows the support wheel to rotate freely under the truck, distributing weight and reducing rolling resistance. Proper bearing function is critical for smooth truck operation and directional control.
Q: How long do polyurethane support wheels typically last?
A: Polyurethane support wheels typically last 1,500 to 3,000 operating hours. Lifespan varies based on floor surface, load cycles, and bearing maintenance. Inspect quarterly and replace if tread is worn or the wheel no longer rolls freely.
Q: What should I inspect to determine if this support wheel needs replacement?
A: Check for visible tread wear, hardening of the polyurethane material, flat spots on the wheel, bearing noise or resistance to rotation, and any cracks in the core. Replace the wheel if any of these conditions are present to maintain truck safety and performance.
