ENTRY AND EXIT ROLLERS
Frequently Asked Questions
Q: What are entry and exit rollers in a manual pallet jack?
A: The entry and exit rollers 00591-43217-81 are small guide wheels mounted on the jack frame sides or ends. They reduce friction as the jack enters and exits beneath a pallet deck, allowing smoother insertion and withdrawal. They protect the main load wheels from binding and distribute side loading.
Q: Which manual pallet jack models use the 00591-43217-81 entry and exit rollers?
A: The 00591-43217-81 entry and exit rollers fit standard manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, Clark, and similar manufacturers. Confirm your jack frame design and mounting location before ordering, as roller diameter and axle configuration vary by model.
Q: When should entry and exit rollers be replaced?
A: Replace the 00591-43217-81 entry and exit rollers if they no longer spin freely, are cracked or flat-spotted, or if you experience grinding or binding when inserting the jack under a pallet. Worn rollers increase friction and make the jack harder to control, particularly when handling skewed loads.
Q: What material are the entry and exit rollers made from?
A: The 00591-43217-81 entry and exit rollers are typically fabricated from polyurethane or nylon with an internal axle bushing or ball bearing. Polyurethane provides good grip on wet floors and cold storage surfaces while offering wear resistance. Nylon variants are lighter and suitable for dry warehouse conditions.
Q: Do entry and exit rollers need regular maintenance?
A: Inspect the entry and exit rollers 00591-43217-81 quarterly and clear any dirt or debris from the axle and surrounding frame. Spin each roller by hand to confirm free rotation. In wet storage or outdoor use, apply a light grease to the axle bushing to prevent rust and binding. Replace if rolling motion is sluggish.
Q: Can entry and exit roller performance affect load handling safety?
A: Yes. Worn or seized entry and exit rollers 00591-43217-81 force the main load wheels to bind or slip sideways when entering and exiting pallet positions. This creates instability, uneven load distribution, and increases the risk of pallet tipping or jack failure. Properly functioning rollers ensure safe and smooth jack maneuvering under all load conditions.
