Product Description
BEARING assembly (SINGLE SHIELD)
Frequently Asked Questions
Q: What does single shield mean on a bearing assembly?
A: Single shield means the bearing assembly has one metal or rubber guard cover on one side only, allowing grease to be applied from the opposite side. This design is common on manual pallet jack load wheels and ride wheels where periodic lubrication is required during normal maintenance.
Q: What is the difference between single shield and double shield bearings?
A: Single shield bearings have one protective cover and allow for grease relubrication. Double shield bearings have seals on both sides and are sealed-for-life, requiring no maintenance but cannot be relubricated. SKU W8012961 is single shield and requires periodic greasing in normal operation.
Q: Which manual pallet jack brands and models use this bearing assembly?
A: This single shield bearing assembly is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, and other OEM manufacturers using standard load wheel or drive wheel specifications. Confirm bearing dimensions and bore size match your equipment before ordering to ensure correct fitment.
Q: What are the specifications of bearing assembly SKU W8012961?
A: Key specifications include bearing bore diameter, outer diameter, width, and load rating. Verify the exact dimensions from your equipment manual or the bearing itself. Single shield design indicates it requires periodic lubrication and can be serviced without wheel removal in many applications.
Q: How long do single shield bearing assemblies typically last?
A: With proper greasing every 500 to 1000 operating hours, single shield bearing assemblies typically last 2 to 5 years in normal material handling service. Lifespan increases with regular maintenance and decreases significantly under heavy-duty use or inadequate lubrication.
Q: What are the failure symptoms of a worn bearing assembly?
A: Worn bearing assemblies produce grinding or squealing noise, rough rotation, play or wobble in the wheel, or visible wear on races and balls. If a wheel becomes difficult to rotate smoothly or noise occurs during normal operation, the bearing assembly likely needs replacement.
