Frequently Asked Questions
Q: What does SU 2377-A include?
A: SU 2377-A is a complete load wheel assembly that includes the SU 2377 wheel bonded to a bearing compatible with 20mm bore axles. The assembly is pre-assembled and ready to slide onto your pallet jack drive axle. Do not disassemble the wheel and bearing, as this will damage both components. Secure the assembly with the retaining clip or lock nut specified for your equipment.
Q: What bearing is included in SU 2377-A?
A: SU 2377-A assembly includes a bearing rated for the SU 2377 wheel specifications and standard 20mm bore electric pallet jack applications. The bearing type and specifications are optimized for the 1,000 lb load rating and 100,000 cycle service life of SU 2377. If you need a bearing-only replacement or a different bearing type, contact our technical support with your pallet jack model number.
Q: Can I use SU 2377-A as a direct replacement for my current wheel assembly?
A: Yes, if your pallet jack has a 20mm bore axle and your current wheel assembly dimensions match the SU 2377 specification. Measure or verify your axle bore and wheel pocket size before ordering. Remove the old assembly by unclipping or unbolting it from the axle. Slide SU 2377-A onto the axle and resecure with the retaining clip or lock nut. If your axle bore or equipment configuration differs, SU 2377-A will not fit correctly.
Q: Is SU 2377-A compatible with both electric and manual pallet jacks?
A: SU 2377-A is designed for electric pallet jack applications only. The wheel and bearing specifications are engineered for powered drive axles. Manual hand-pump jacks have different load ratings and duty cycles and require different wheel assemblies. Do not use SU 2377-A on manual equipment as this violates the load rating and shortens wheel life.
Q: How do I remove and replace SU 2377-A on my pallet jack?
A: Unclip or unbolt the assembly from the axle shaft. If stuck due to corrosion, tap the axle end gently with a soft mallet to help release the bore. Do not pry sideways as this damages the bearing. Clean the axle shaft with a wire brush if corroded. Slide the new SU 2377-A assembly onto the axle shaft and secure with the retaining clip or lock nut. Verify the assembly spins freely and does not wobble before operating the jack.
Q: What is the expected lifespan of SU 2377-A in heavy-use applications?
A: Under normal conditions within the 1,000 lb load rating, SU 2377-A is rated for 100,000 cycles per ANSI MH27.1. Heavy continuous use, high temperatures, rough or contaminated floors, or loads above 1,000 lbs reduce actual lifespan. Inspect the wheel monthly in high-use environments. Replace SU 2377-A when the polyurethane tread wears flat or through to the steel core, when the bearing becomes noisy, or when the wheel does not roll freely.
