Frequently Asked Questions
Q: What is CL 993967 and how does it differ from standard open bearings?
A: CL 993967 is a sealed bearing engineered for Clark manual pallet jacks, specifically designed for load roller and wheel assemblies. The synthetic polymer seals provide maintenance-free operation and exclude moisture and contamination from internal bearing races and rolling elements.
Q: What material is CL 993967 constructed from?
A: CL 993967 features heat-treated chrome steel bearing races and rolling elements for high load capacity and durability. Synthetic polymer seals are integrated to eliminate the need for periodic lubrication and extend service life in warehouse and material handling applications.
Q: Which Clark manual pallet jack models use CL 993967?
A: CL 993967 fits Clark model 6600 manual pallet jacks. It is designed for load roller and wheel assemblies that experience continuous rotation during pallet movement and stacking operations.
Q: Why are sealed bearings like CL 993967 preferred over open bearings in material handling?
A: Sealed bearings eliminate scheduled maintenance and re-lubrication in warehouse environments. The synthetic polymer seals protect internal races from dust, moisture, and debris, providing longer service intervals and reduced total cost of ownership compared to open bearings that require periodic cleaning and lubrication.
Q: What is the expected service life of CL 993967 in continuous pallet jack operation?
A: CL 993967 is rated for continuous rolling duty typical of manual pallet jack operation. Sealed bearing lifespan depends on load cycles, operating conditions, and storage environment. The sealed design extends service life by reducing contamination exposure. Replace if bearing noise or rolling resistance increases.
Q: Are there cross-reference or equivalent part numbers for CL 993967?
A: CL 993967 is the original Clark part number. Use this exact SKU to ensure compatibility with Clark model 6600 pallet jacks and proper load rating for sealed wheel bearing applications.
