Frequently Asked Questions
Q: What is the function of exit roller bolt 50137105?
A: An exit roller bolt secures the guide roller or load wheel assembly to the mast or load carriage on manual pallet jacks. The bolt passes through the roller hub and brackets to create a fixed pivot point. Bolt 50137105 is sized for the standard exit roller assembly on manual pallet trucks.
Q: Which manual pallet jack brands use exit roller bolt 50137105?
A: Exit roller bolt 50137105 is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Clark, CAT, and Mitsubishi. Confirm the bolt diameter, length, and thread pitch match your equipment. Check the mast exit roller assembly to verify the correct bolt specification.
Q: What material is exit roller bolt 50137105?
A: Exit roller bolts are typically made from zinc-plated steel for corrosion protection or stainless steel for wet and harsh environments. The bolt carries shear load from the exit roller weight and load arm geometry. Material selection affects durability in wet storage or outdoor use.
Q: What torque or tightness level should exit roller bolt 50137105 have?
A: Refer to the equipment manufacturer service manual for the correct torque specification. The bolt must be tight enough to prevent roller play, which causes uneven mast travel and binding. A loose exit roller bolt causes the load arm and mast to bind during lifting, which stresses other components.
Q: When should exit roller bolt 50137105 be replaced?
A: Replace the exit roller bolt if it becomes loose despite tightening, shows visible cracks or deformation, or exhibits corrosion that weakens the bolt. During routine inspection, check that the exit roller rotates freely without resistance and the bolt does not allow lateral movement. Replace worn bolts before they fail completely.
