20MM x 47MM x 14MM Sealed Ball Bearing Assembly for Manual Pallet Jack

Frequently Asked Questions

Q: What are the exact dimensions of the NA013435 bearing assembly?
A: The NA013435 is a sealed deep groove ball bearing with a 20 mm bore, 47 mm outer diameter, and 14 mm width. These dimensions are critical for load wheel fitment on manual pallet jacks. Verify your equipment uses these exact measurements before ordering.

Q: What material is the NA013435 bearing made from?
A: The NA013435 is constructed from high-carbon chrome steel, typically SAE 52100 or equivalent grade. This material provides superior hardness and wear resistance for extended service life in load-bearing wheel applications on manual pallet jacks.

Q: What seal type does the NA013435 use and why?
A: The NA013435 features a rubber contact seal in 2RS (two rubber seal) configuration. These seals keep contaminants out and lubrication in, protecting the bearing races and rolling elements from dirt, moisture, and debris common in warehouse environments.

Q: Which manual pallet jack brands is the NA013435 compatible with?
A: The NA013435 fits multiple manual pallet jack models from Crown, Toyota, Raymond, Yale, Hyster, and similar OEMs. Always verify your equipment model and serial number match this bearing size before purchasing to ensure proper fitment.

Q: How long will the NA013435 bearing last under typical use?
A: Service life depends on load weight, floor condition, and maintenance. With regular inspection and lubrication, the NA013435 typically performs for thousands of operating hours. Replace when you notice grinding noise, wheel wobble, or excessive play in the load wheel.

Q: What are common failure symptoms that indicate the NA013435 needs replacement?
A: Common failure symptoms include grinding or squealing noise from the load wheel, lateral play or wobble when the wheel is spun by hand, flat spots or uneven wear on the wheel surface, and resistance or grinding when pumping the pallet jack handle.
