Product Description
43204-TT is a precision sealed ball bearing assembly engineered for manual pallet jack wheel applications. Manufactured to strict tolerances from SAE 52100 hardened chromium steel, this bearing measures 20 mm inner diameter by 47 mm outer diameter by 14 mm width. It is double-sealed for durability in warehouse conditions and supports both load and steer wheel functions on most major pallet jack brands.

Frequently Asked Questions
Q: What are the exact dimensions of the 43204-TT bearing?
A: The 43204-TT is a precision sealed ball bearing with a 20 mm inner diameter, 47 mm outer diameter, and 14 mm width. These dimensions are consistent with manual pallet jack wheel hub requirements from Crown, Toyota, Raymond, Yale, and Hyster equipment.
Q: What is the material grade of the 43204-TT bearing races and balls?
A: The 43204-TT uses SAE 52100 hardened chromium steel for both the inner and outer races and the rolling balls. This premium material grade provides high compressive strength and wear resistance in warehouse loading conditions.
Q: How is the 43204-TT sealed and what protection does it provide?
A: The 43204-TT features double seals on both sides that retain bearing lubricant and exclude moisture, dust, and contaminants. Double-sealed design extends bearing life significantly in wet storage facilities, cold storage areas, and humid warehouse environments compared to single-shield designs.
Q: Can the 43204-TT be used for both load wheel and steer wheel applications?
A: Yes, the 43204-TT is engineered for both load wheel and steer wheel functions on manual pallet jacks. It supports the radial and axial loads required for steering control and load support across major pallet jack brands.
Q: What is the expected service life of the 43204-TT bearing?
A: Under normal warehouse conditions with consistent use, the double-sealed design typically provides extended service life compared to single-shield bearings. Replace when you observe dragging, steering resistance, wheel wobble, or grinding noise that indicates internal wear.
Q: How does the 43204-TT compare to the open 43204 bearing?
A: The 43204-TT is sealed while the standard 43204 is single-shield. Both share the same 20 mm x 47 mm x 14 mm dimensions and fit the same pallet jack wheel hubs. The 43204-TT provides superior protection in wet or cold storage environments and typically lasts longer before requiring replacement.
