Load wheel bearings reduce rolling friction, allowing the wheels to spin freely and smoothly while supporting the weight of the pallet jack and its load. This is achieved using small metal balls or rollers that minimize the contact area with the surfaces they roll on, thus reducing resistance.

Why Choose Pallet Jackson for Load Wheel Bearings
Purpose and Function Load Wheel Bearings?
Load wheel bearings serve the primary function of reducing friction and supporting the radial and axial loads exerted by the weight of the load on the pallet jack. The quantity and size of load wheel bearings vary depending on the pallet jack's design and capacity.
Load wheel bearings are especially important in pallet jacks due to the manual handling involved in maneuvering the equipment. They must be robust enough to handle the thrust loads of high-speed cornering, hard acceleration, and braking. Proper maintenance and timely replacement of these bearings are essential to prevent downtime and ensure the safety and efficiency of the pallet jack's operation.
Types of Load Wheel Bearings
These types of load wheel bearings are commonly used in pallet jacks:
Ball Bearings
Ball bearings are the most common type used in pallet jack wheels. They are designed to handle both radial and thrust loads, making them suitable for carrying heavy weights while allowing for smooth motion.
Roller Bearings
Roller bearings are designed to carry heavy radial loads. They are ideal for applications where the movement is linear. Their cylindrical shape allows for a larger contact area, distributing the load more evenly.
Tapered Roller Bearings
Tapered roller bearings are engineered to handle large radial and thrust loads. Their unique design efficiently manages forces in radial and axial directions, which is beneficial when a pallet jack changes direction.
Needle Roller Bearings
Needle roller bearings are a type of roller bearing with slender and long rollers. They are used in pallet jacks where limited space and a high load capacity are required. Despite their small diameter, they can still support high loads.
Plain Bearings
Plain bearings, also known as bushings, are the simplest. They are used in pallet jacks for applications that require sliding motion rather than rolling. They are cost-effective and can operate under high-load conditions.
Thrust Bearings
Thrust bearings are designed to handle axial loads. While not typically used in pallet jack wheels, they can be found in the lifting mechanism, where they help manage the forces when raising and lowering loads.
Two Common Materials of Load Wheel Bearing
These two materials are common;y used for the construction of load wheel bearings:
Chrome Steel
Chrome steel, known for its high strength and durability, is a traditional material used to manufacture load wheel bearings. It is favored for its cost-effectiveness and high load-bearing capacity, making it suitable for heavy-duty applications such as pallet jacks. However, it is heavier than other materials and prone to corrosion if not properly protected.
Stainless Steel
Stainless steel is another common material for load wheel bearings, offering a balance between strength and resistance to corrosion. This material is less prone to rusting, which makes it a reliable choice for applications where the bearings are exposed to moisture or corrosive elements. The added benefit of stainless steel is its maintenance of integrity over time, ensuring longevity in performance.
Factors to Consider Before Buying Load Wheel Bearing
By considering these factors, you can ensure that you select the right load wheel bearings for your pallet jack.
Load Capacity
The load-bearing capacity of the wheel bearings is paramount. Ensure the bearings can withstand the maximum weight of the loads typically handled by your pallet jack.
Material Quality
Wheel bearings are available in various materials, each with different durability and performance levels. Choose a material that offers a balance between longevity and cost-effectiveness.
Compatibility
Check the wheel bearings' compatibility with your pallet jack model. Incorrect sizing or type can lead to inefficient operation or damage.
Environmental Conditions
Consider the pallet jack's working environment. Bearings must be suitable for the conditions, whether in cold storage or a dusty warehouse.
Price vs. Performance
While budget is an important consideration, investing in higher-quality bearings can reduce long-term costs associated with repairs and downtime.
Warranty and Support
Look for products with a warranty that covers defects and provides support for any issues that may arise during usage.
How to Replace an Electric Pallet Jack Load Wheel Bearing
Replacing the load wheel bearings on an electric pallet jack is a task that can significantly extend the life of your equipment.
Here are the steps::
Tools Required
-
Socket set
-
Screwdrivers (flathead and Phillips)
-
Pliers
-
Hammer
-
Bearing puller
Step 1: Prepare the Pallet Jack and Work Area
Ensure the pallet jack is powered off and the battery is disconnected. Clear the work area of any obstacles and lay down a protective mat to prevent damage to the floor and the equipment.
Step 2: Remove the Wheel Assembly
Use the appropriate socket to loosen the bolts securing the wheel assembly. Carefully remove the assembly and set it aside on a flat surface.
Step 3: Extract the Old Load Wheel Bearing
With the wheel assembly removed, locate the bearing retainer clips or caps. Use pliers to remove these, then gently tap out the old bearing with a hammer, applying even force to avoid damage.
Step 4: Install the New Load Wheel Bearing
Clean the bearing housing to remove any debris. Place the new bearing into the housing, ensuring it is seated evenly. Use the bearing puller to press it firmly into place.
Step 5: Reassemble
Reverse the disassembly process to reattach the wheel assembly. Ensure all bolts are tightened securely.
