Frequently Asked Questions
Q: What equipment types does the PLT-P0021-PY polyurethane wheel assembly fit?
A: The PLT-P0021-PY is designed for lift trucks, pallet jacks, and industrial caster applications. The polyurethane tread bonded to either cast iron or polypropylene core construction makes it suitable for diverse material handling equipment requiring precision load wheels.
Q: What are the dimensions and bearing specifications of the PLT-P0021-PY?
A: The PLT-P0021-PY features a sealed precision ball bearing with 8 mm bore, 35 mm outer diameter, and 12 mm width. The bearing is constructed from GCr15 high-strength steel, providing durability and smooth operation in industrial material handling environments.
Q: What wheel materials and load capacities does the PLT-P0021-PY offer?
A: The PLT-P0021-PY uses polyurethane tread bonded to either cast iron or polypropylene core. Typical load capacities range from 600 lbs for smaller versions up to 1200 lbs for larger assemblies, depending on the specific application and wheel diameter configuration.
Q: What is the durometer hardness and operating temperature range for the PLT-P0021-PY?
A: The PLT-P0021-PY polyurethane tread has a durometer hardness of 75 Shore A, providing balanced traction and wear resistance. The assembly operates reliably from minus 40 degrees Fahrenheit to plus 180 degrees Fahrenheit, making it suitable for standard warehouse and cold storage environments.
Q: What is the core material difference in PLT-P0021-PY wheel options?
A: The PLT-P0021-PY is available with either a cast iron core for heavy-duty load handling applications or a polypropylene core for lighter-duty service. Cast iron provides maximum load capacity and durability, while polypropylene offers reduced weight and is suitable for standard pallet jack and caster applications.
Q: What bearing material does the PLT-P0021-PY use?
A: The PLT-P0021-PY bearing is constructed from GCr15 high-strength bearing steel, sealed to protect against contamination and moisture. This material provides excellent durability and precision performance in industrial material handling service.
