Weight Capacity of 1-3/4 Inch Square Tube Axle

Updated 03/25/2021 | Published 03/22/2021

Question:

What would be the weight capacity of a square axle, 1 3/4 inch square. The inner bearing is a Timkin LM 48548. The outer bearing is a Bower L44649. The spindle where the inner bearing rides is 1 3/8 inch diameter, and where the outer bearing rides is 1 1/16inch diameter my calipers only measure in inch fractions not inch decimals. Regards

We don't offer any axles or hubs that are compatible with that wheel bearing set, but a 1-3/4 inch square axle would typically carry a 1000-2000 lb capacity.

If you were needing a replacement axle, I'd be happy to look through our offerings of off-the-shelf axle sizes and check if we have anything that would be compatible. I'd need to know the hub face to hub face distance and the center to center spacing of the spring seats. I'd also need to know the wheel bolt pattern.
