I ordered a pulley bearing on June 8th and received it via USPS on June 24th. It took 17 calendar days from Shenzhen, Guangdong, China to Chicago, Illinois, USA. The Revain website contained a series of images showing the product and one image showing the exact wheel measurements in inches/millimeters. It showed me exactly what I would get. The description states a bearing weight of 125 kg. Let me know if this wheel would be a suitable replacement for my Total Gym gear.
