Q: What are the wheel dimensions for CR 813129?
A: CR 813129 features a 3.50 inch outside diameter, 2.00 inch tread width, and 2.17 inch inside diameter bore. These dimensions are truck-specific for Crown ST 3000 Series fitment. The wheel accepts integral bearing assemblies and must be measured during inspection to confirm correct replacement sizing.
Q: What material composition and hardness is CR 813129 manufactured with?
A: CR 813129 is manufactured with Durarun 95A polyurethane compound, rated 95A on the Shore A hardness scale. This polyurethane formulation is engineered for heavy-duty warehouse and industrial environments. The 95A durometer provides load-carrying capability and wear resistance in material handling applications.
Q: What cross-reference part numbers apply to CR 813129?
A: CR 813129 cross-references as 813129 and CR813129. No superseded or prior designation numbers are documented. When searching supplier inventory or OEM databases, request the part by any of these three numbers: CR 813129, 813129, or CR813129.
Q: How long does CR 813129 polyurethane wheel typically last before replacement?
A: Durarun 95A polyurethane wheels typically provide 18 to 30 months of service in normal warehouse conditions. Actual lifespan depends on floor surface, truck load capacity utilization, and daily runtime hours. Inspect regularly for uneven wear, flat spots, or cracking. Replace when tread depth drops below 2mm or wheels develop noise or binding during rotation.
