Frequently Asked Questions
Q: What Raymond equipment models is the RA 442-210 designed for?
A: The RA 442-210 is an OEM radial roller bearing specified for Raymond 8300, 8400, and 8500 Series electric lift trucks. It is engineered for axle and wheel assembly applications in these series. Confirm your equipment model matches the 8300, 8400, or 8500 Series designation before ordering this bearing.
Q: What is the material composition of the RA 442-210?
A: The RA 442-210 is constructed from hardened alloy steel designed to withstand the combined radial and axial loads of lift truck wheel and axle assemblies. The hardened steel provides superior wear resistance and load capacity compared to standard bearing steel, ensuring durability in the demanding 8300, 8400, and 8500 Series operating environment.
Q: Why is the RA 442-210 a radial roller bearing instead of a ball bearing?
A: The RA 442-210 radial roller bearing design handles higher combined radial and axial loads than ball bearings. The roller configuration distributes load across a larger contact area, reducing stress concentration and enabling longer service life in 8300, 8400, and 8500 Series wheel and axle assemblies where sustained heavy loads occur.
Q: What does the double seal configuration on the RA 442-210 accomplish?
A: The double seal design on the RA 442-210 provides dual protection against contamination and moisture while retaining the factory lubricant. This sealed architecture is critical for wheel assembly applications exposed to wet floors and outdoor conditions common in electric lift truck operations. The seals extend bearing life by preventing water and dirt ingress.
Q: Is the RA 442-210 pre-lubricated, or does it require greasing during assembly?
A: The RA 442-210 arrives pre-lubricated with the double seals intact. Install the bearing directly into the 8300, 8400, or 8500 Series axle or wheel assembly without additional greasing or disassembly. The sealed lubricant supports operational life without maintenance intervention.
Q: What is the typical service life of the RA 442-210 in a Raymond 8300, 8400, or 8500 Series lift truck?
A: Service life depends on load conditions, duty cycle, and maintenance practices. The hardened alloy steel and double seal design typically support 2-4 years of continuous industrial material handling use. Monitor the bearing for noise, vibration, excessive play, or heat increases, which indicate wear requiring replacement.
