Q: What are the specifications for the AT Z-1133 bearing?
A: The AT Z-1133 is a deep groove bearing with a 20 mm bore diameter. It features rubber shielding for contamination protection and is designed for use in Atlas manual pallet jack assemblies. The rubber-shielded design provides basic protection in typical material handling environments.

Q: Which Atlas pallet jack models use the AT Z-1133 bearing?
A: The AT Z-1133 bearing is compatible with Atlas manual pallet jacks, specifically model AT Z1133 and alternate model ATZ1133. Verify your equipment model before ordering to ensure compatibility.

Q: Is there a cross-reference part number for the AT Z-1133?
A: The AT Z-1133 bearing has an alternate model designation of ATZ1133. Both the manufacturer part number and OEM part number are AT Z-1133. Use these designations when ordering replacement parts.

Q: What type of failure symptoms indicate the AT Z-1133 bearing needs replacement?
A: Signs of bearing wear include audible grinding or squeaking during jack operation, increased friction in the mast assembly, or visible corrosion on the bearing surfaces. Rubber shielding degradation may allow moisture entry, accelerating internal corrosion and bearing failure.

Q: How does the rubber shielding on the AT Z-1133 affect durability?
A: Rubber shielding provides moderate protection against dust and light moisture ingress but is not a complete seal. In wet environments or outdoor storage, the rubber material can deteriorate over time. Regular inspection is recommended for equipment used in cold storage or wet floor applications.
