BT 49748-00

Frequently Asked Questions

Q: What are the dimensions of the BT 49748-00 bearing?
A: The BT 49748-00 is a sealed deep groove ball bearing with the following dimensional profile: 17 mm inner diameter (ID), 47 mm outer diameter (OD), and 14 mm width. These precision dimensions ensure proper fitment in BT manual pallet jack load wheel assemblies.

Q: What materials are used in the BT 49748-00 bearing?
A: The BT 49748-00 features high-carbon steel precision-ground races, AISI 52100 chromium steel balls, and a steel cage for ball retention. The bearing includes double-lip rubber seals (2RS) to protect against contamination and retain lubricant in warehouse and dock environments.

Q: What is the BT 49748-00 bearing designed for?
A: The BT 49748-00 is a precision replacement bearing for BT manual pallet jack load wheels. It is engineered to handle continuous rotational stress, load transfer, and environmental exposure typical in material handling applications including dock, warehouse, and yard operations.

Q: Why does the BT 49748-00 have double-lip rubber seals?
A: The double-lip rubber seals (2RS) provide dual protection: the outer lip excludes moisture, dust, and debris from the bearing races, while the inner lip retains factory grease lubrication. This design maximizes bearing lifespan in contaminated dock and warehouse environments.

Q: When should I replace the BT 49748-00 bearing?
A: Replace the BT 49748-00 if you observe load wheel wobble, grinding noise during operation, increased friction, or visible scoring on the races. Worn bearings reduce load wheel performance and compromise safe pallet handling.

Q: What BT pallet jack models use the BT 49748-00?
A: The BT 49748-00 is compatible with BT manual pallet jacks using BT load wheel assemblies. Verify your equipment model and wheel assembly configuration before ordering to ensure this bearing is the correct replacement for your lift truck.
