Frequently Asked Questions
Q: Which pallet jack models is the 0000-203/210-1-A-D compatible with?
A: The 0000-203/210-1-A-D is designed for Mobile ML55 newer model pallet trucks and Ultra UL 5500 equipment. For earlier ML55 variants or other brands, verify bearing pin diameter and hub width specifications match before ordering.
Q: What are the key specifications of this load roller?
A: This roller features a ultra-polyurethane tread bonded to a machined 6061-T6 aluminum hub with sealed steel ball bearings. The aluminum hub reduces weight while maintaining strength, and the sealed bearings prevent contamination.
Q: Why is aluminum used for the hub material?
A: 6061-T6 aluminum offers high strength-to-weight ratio, reducing overall roller weight compared to steel hubs. This lowers rolling resistance and operator fatigue. Aluminum resists corrosion better than steel and is machined to precision tolerances, making it ideal for high-use warehouse environments.
Q: What part numbers does this load roller cross-reference or supersede?
A: The 0000-203/210-1-A-D supersedes MO 203/210-1-A and is equivalent to UL 1227-D and MO 120X205-A-D. It replaces RL WHL-5013-TPTUM. Always verify bearing pin size and hub width match your equipment before substituting.
Q: What is the expected service life of this roller?
A: Sealed steel ball bearings and ultra-polyurethane tread typically deliver 3-5 years of service in normal warehouse conditions. The low rolling resistance of the aluminum hub reduces bearing stress, extending component life. Service life depends on load weight, frequency of use, and floor cleanliness. Monitor for rolling resistance increases or audible bearing noise as signs of wear.
Q: Is this roller better for high-capacity or high-frequency applications?
A: The sealed bearing design and lightweight aluminum hub excel in high-frequency, continuous-use environments with reduced maintenance requirements. Confirm your pallet jack weight rating matches your intended load capacity.
Q: How should this load roller be stored when not in use?
A: Store in a cool, dry location away from direct sunlight and moisture. Keep sealed bearings protected from contamination. Store uprights to prevent flat-spotting the tread. Inspect periodically for corrosion on the aluminum hub or bearing surfaces.
