CR 74602

Frequently Asked Questions

Q: What is the CR 74602 bearing and where does it fit?
A: The CR 74602 is a sealed deep groove ball bearing for manual pallet jack assemblies made by Crown. It is a 25mm bore diameter bearing manufactured from chrome alloy steel with synthetic rubber (NBR) seals.

Q: What material is the CR 74602 bearing made from?
A: The CR 74602 uses chrome alloy steel (bearing grade) races and balls with synthetic rubber (NBR compound) seals. The races are precision ground steel with anti-corrosion treatment to resist rust and wear.

Q: Is the CR 74602 bearing sealed for life?
A: Yes. The CR 74602 is factory pre-lubricated and sealed for life. The rubber seals are permanent; the bearing cannot be disassembled or re-lubricated. It is designed for high-impact manual material handling without maintenance.

Q: How long does the CR 74602 bearing typically last?
A: Sealed deep groove ball bearings like the CR 74602 typically last 3-5 years in manual pallet jack service, depending on load, environment, and operation frequency. Wet, cold, or corrosive environments may reduce lifespan.

Q: What are symptoms of CR 74602 bearing failure?
A: Watch for grinding or squealing noise from the jack wheels, rough or gritty rotation when moving the jack, or visible seal damage. These indicate internal wear or seal failure and mean the bearing must be replaced.
