Frequently Asked Questions
Q: What equipment is the RA 442-140 bearing compatible with?
A: The RA 442-140 is an OEM ball bearing designed for Raymond electric industrial lift trucks. Equivalent part numbers include RAY-442-140 and RA442140 for cross-reference purposes. This is a genuine Raymond component manufactured to OEM specifications for precision fit in Raymond equipment.
Q: What materials are used in the RA 442-140 bearing?
A: The RA 442-140 uses high carbon chromium steel for the races and balls, providing superior hardness and load capacity. The bearing features stainless steel double metal shields for corrosion resistance and contamination protection. This material combination ensures durability in industrial material handling environments.
Q: How do the double metal shields protect the bearing?
A: The stainless steel double shields on the RA 442-140 provide a sealed enclosure that prevents dirt, moisture, and debris from entering the bearing cavity. The shields also retain the pre-applied lubricant, extending service life. This design is critical for lift truck axle and wheel assembly applications exposed to wet and dusty conditions.
Q: Is the RA 442-140 pre-lubricated?
A: Yes, the RA 442-140 arrives pre-lubricated and sealed. The double shield design traps the lubricant inside, supporting radial load performance throughout the bearing lifecycle. The bearing requires no additional lubrication and should not be disassembled for re-greasing.
Q: What load capacity does the RA 442-140 support?
A: The RA 442-140 is engineered to support radial loads typical of electric lift truck axle, wheel, and hydraulic system applications. Consult your equipment documentation for specific load ratings. The high carbon chromium steel construction handles sustained loads without premature failure when properly installed.
Q: What are the equivalent part numbers for the RA 442-140?
A: The OEM part number is RA 442-140. Cross-reference equivalent part numbers include RAY-442-140 and RA442140. When ordering, use the RA 442-140 designation to avoid confusion with similar bearing models.
