Frequently Asked Questions

Q: What are the complete specifications for the CA PO-0423-A caster assembly?
A: The CA PO-0423-A is a 4.00 inch diameter caster assembly with a 1.25 inch tread width. It features a polyolefin core with soft thermoplastic rubber tread, zinc plated steel mounting plate with 2.625 x 3.625 inch bolt pattern, annular bearing, double ball raceway swivel, and a 260 lbs rated load capacity. The wheel durometer is 65 Shore A with operational temperature range from -45°F to 180°F.

Q: What is the wheel material composition and what does the 65 Shore A durometer mean?
A: The CA PO-0423-A has a polyolefin core with soft thermoplastic rubber tread. The 65 Shore A durometer indicates the rubber hardness is soft and flexible, providing good traction and shock absorption. This material composition offers a balance between grip, durability, and floor protection. Soft rubber wheels are suitable for various floor types and absorb vibration better than harder compounds.

Q: What is the load rating for the CA PO-0423-A and what cart applications does it support?
A: The CA PO-0423-A has a 260 lbs rated load capacity per caster. This makes it suitable for light to medium-duty cart applications. Confirm your cart requires a 4 inch wheel and can accommodate the zinc plated mounting plate with a 2.625 x 3.625 inch bolt pattern. For heavier loads or larger wheels, specify equipment requirements and select an appropriate alternative.

Q: What are the mounting specifications and how does it attach to equipment?
A: The CA PO-0423-A mounts via a zinc plated steel plate with a 2.625 x 3.625 inch bolt pattern. This configuration is standard for cart caster applications and accepts mounting bolts at specified spacing. Verify your equipment has matching bolt hole spacing and plate height clearance before ordering. The zinc plating provides corrosion resistance.

Q: What is the operational temperature range and does this wheel have a maintenance fitting?
A: The CA PO-0423-A operates reliably from -45°F to 180°F, making it suitable for indoor environments from cold storage to standard room temperature. The assembly includes a factory grease fitting, allowing for periodic lubrication to extend bearing and swivel life. The double ball raceway swivel supports smooth directional movement and load distribution.

Q: Does the CA PO-0423-A come with bearing and swivel pre-installed?
A: Yes. The CA PO-0423-A is a complete caster assembly with annular bearing and double ball raceway swivel pre-installed. The wheel, mounting plate, bearing, and swivel are ready for direct attachment to your cart. No additional bearing or swivel installation is required.
