Precision Sealed Bearing Assembly for Pallet Jacks

Frequently Asked Questions

Q: What are the exact dimensions and load rating of the 2I6972 bearing assembly?
A: The 2I6972 is a sealed radial ball bearing with a 20mm bore diameter, 47mm outside diameter, and 14mm width. It is rated for manual pallet jacks with loads up to 5,500 lbs. Chrome steel construction (AECI 52100 equivalent) with ABEC 1 tolerance ensures durability and precision fitment.

Q: What applications and equipment does the 2I6972 support?
A: The 2I6972 is engineered for load and steer wheel assemblies on manual pallet jacks from Crown, Toyota, Raymond, Yale, and Hyster models with 20mm axles. It is suitable for standard warehouse duty cycles including indoor and light outdoor use at rated 5,500 lb capacity.

Q: How do the double rubber seals on the 2I6972 protect the bearing?
A: Double rubber seals on the 2I6972 create a dual barrier against dirt, moisture, and debris ingress. The inner and outer seals minimize contamination of the bearing raceways and lubrication, extending service life in warehouse environments. Sealed construction reduces maintenance requirements compared to open bearings.

Q: Is the 2I6972 factory lubricated and what is the maintenance requirement?
A: Yes, the 2I6972 arrives factory lubricated with grease suitable for standard manual pallet jack duty. The sealed design minimizes re-lubrication needs. In normal warehouse use, bearing lifespan is typically 18 to 36 months depending on floor conditions and equipment cycles. Replace bearings if you observe noise, rough rotation, or play in wheels.

Q: Can the 2I6972 be used interchangeably with the 2I7187?
A: Both the 2I6972 and 2I7187 share identical dimensions (20mm bore, 47mm OD, 14mm width) and are compatible with the same pallet jack axles and wheel assemblies. Both use chrome steel construction and rubber seals. Either bearing will function in equivalent applications, though verify your equipment OEM part number to confirm the specified bearing for your model.
