Frequently Asked Questions
Q: What are the dimensions and material specifications for the JU 51237318 caster wheel assembly?
A: The JU 51237318 is a 4.00 inch diameter caster wheel with a 2.50 inch tread width. The wheel is constructed from high-performance polyurethane rated at 95A Shore durometer hardness, mounted on a machined steel core with powder coat finish. The polyurethane tread provides durable contact surface suitable for standard material handling applications.
Q: Which Jungheinrich equipment models does the JU 51237318 fit?
A: The JU 51237318 is an OEM part designed for Jungheinrich electric pallet trucks and designated for Millennium Standard caster applications. Verify your equipment documentation to confirm compatibility before ordering, as fitment depends on specific model year and caster position.
Q: What does the 95A Shore hardness rating mean for this wheel?
A: The 95A durometer hardness indicates a firm, high-performance polyurethane compound designed for rigorous use in material handling. This hardness level provides good load-bearing capacity and wear resistance while maintaining traction on typical warehouse floors. The compound is not optimized for wet or cold storage environments.
Q: What is the difference between JU 51237318 and JU 51237318-SG?
A: The JU 51237318-SG variant includes polymer composite string guards in addition to the standard wheel assembly. Both share the same 4.00 inch diameter, 2.50 inch width, and 95A polyurethane construction. The string guards provide edge protection and reduce debris accumulation on the caster. Select the -SG variant if your equipment has string guard provisions.
Q: What maintenance is required for the JU 51237318 caster wheel?
A: The wheel features sealed bearings that require no lubrication. Periodically inspect the polyurethane tread for embedded debris or wear. Clean the wheel surface with a damp cloth as needed. The 95A durometer compound is durable and does not require special conditioning. Replace the wheel when tread wear becomes visible or diameter loss affects equipment performance.
