Product Description
GW 225 cup, bearing is a hardened steel bearing race manufactured for manual pallet jack load wheel assemblies. Designed for compatibility with GW225, GP 225, and GP225 part numbers, this component serves as a direct replacement for standard manual pallet jack bearing cups. Precision machined for industry-standard fit, the GW 225 cup, bearing withstands typical intermittent load cycles experienced in manual pallet jack operation.

Frequently Asked Questions
Q: What is GW 225 and what does it do?
A: GW 225 is a hardened steel bearing cup (bearing race) used in manual pallet jack load wheel assemblies. It serves as the stationary race that supports the rolling ball bearings in the load wheel hub. The bearing cup is pressed or installed into the wheel bore and works with a matching axle to create a sealed bearing assembly.
Q: What are the equivalent part numbers for GW 225?
A: GW 225 is equivalent to GW225, GP 225, and GP225. All four part numbers refer to the same hardened steel bearing cup. Use any of these part numbers when ordering; they are direct interchanges. Confirm the part number on your existing wheel before purchasing to ensure proper fit.
Q: How is GW 225 finished and what is its material composition?
A: GW 225 is manufactured from hardened steel and features a machined, polished bearing cup finish. The polished surface reduces friction and wear on the ball bearings during rotation. The hardened steel resists rolling contact fatigue and provides long-term durability under repetitive load cycles typical of manual pallet jack operation.
Q: How do I install or replace a GW 225 bearing cup?
A: Remove the load wheel assembly from the pallet jack frame. Press or tap out the worn GW 225 cup using a bearing cup removal tool or soft-face hammer. Clean the wheel bore thoroughly. Press the new GW 225 bearing cup into the bore using a bearing press or appropriate installation tool, ensuring it sits fully and squarely. Do not allow the cup to tilt or become misaligned during installation. Reassemble the load wheel and test rotation.
Q: What axle shaft size works with GW 225?
A: GW 225 bearing cups are designed to accept a specific axle shaft diameter determined by the pallet jack manufacturer. Do not assume the cup size without verification. Measure your existing bearing cup bore or consult the wheel and jack documentation to confirm the correct axle size. Installing a mismatched axle will result in loose or binding wheel operation.
Q: Why does a GW 225 bearing cup need replacement?
A: Replace GW 225 if the bearing cup develops visible spalling (pitting), scoring, or wear grooves on the polished surface. Signs of failure include grinding or squeaking sounds from the load wheel, loss of wheel smoothness, or play between the cup and axle. A worn cup cannot be repaired and must be replaced to restore proper wheel function and prevent bearing damage.
