3002729

Frequently Asked Questions

Q: What are the exact specifications for bearing assembly 3002729?
A: Bearing assembly 3002729 features a 20 mm inner diameter, 47 mm outer diameter, and 14 mm width. It is a sealed ball bearing with dual metal shields and case-hardened steel construction. The design includes machined, uncoated race surfaces that provide precise load distribution. This sealed bearing assembly is rated for high-load material handling applications including manual pallet jack load wheel and drive wheel positions.

Q: What equipment is bearing 3002729 compatible with?
A: Bearing 3002729 fits manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Clark, Mitsubishi, and CAT. The 20 mm x 47 mm x 14 mm dimensions make it suitable for both load wheel and drive wheel applications. Always verify dimensions on your equipment before ordering to confirm compatibility.

Q: Why does bearing 3002729 have dual metal shields?
A: The dual metal shields on bearing 3002729 provide multi-stage protection against moisture, dust, and debris in warehouse and dock environments. Metal shields are superior to rubber seals for material handling equipment because they withstand temperature extremes and do not degrade in wet or cold storage conditions. This design extends bearing life in harsh operating environments.

Q: Is bearing 3002729 suitable for wet floor or cold storage use?
A: Bearing 3002729 is well-suited for wet floor and cold storage applications. The sealed ball bearing design with dual metal shields prevents water and ice from compromising internal race surfaces. The case-hardened steel material remains stable at temperatures below 0 degrees Celsius. For optimal performance in cold storage below negative 10 degrees, verify that the jack is rated for this temperature range.

Q: How long should bearing assembly 3002729 last before replacement?
A: Bearing assembly 3002729 typically provides 3 to 5 years of service life under normal warehouse operation. Heavy continuous use, wet environments, or irregular maintenance may reduce this timeframe. Inspect the bearing quarterly for noise, lateral movement, or resistance. If grinding sounds occur or the wheel feels rough when turning, replacement is needed.

Q: Does bearing 3002729 require any special maintenance?
A: Bearing 3002729 is sealed and does not require relubrication. No tools or special procedures are necessary for routine maintenance. Perform visual inspections quarterly to confirm the shields are intact and the bearing races are free from visible corrosion. Keep the bearing area clean and dry. If water or salt accumulates around the bearing, clean it promptly to prevent long-term damage.
