I couldn't be more pleased! The bearings on my central vacuum motor went out and I was facing a bill of $200 to replace the motor. Figured I'd try to replace the bearings myself, but after disassembling the motor I found that the bearings were mixed dimension - metric OD and width, but 5/16" ID for the shaft. Wasn't able to locate a suitable replacement until I found your website. The Dimension Search page made it quite easy to find what I was looking for. Also appreciate that you provided free 1st Class USPS shipping and no additional handling charge - many companies add excessive charges for these items. The bearings shipped out the next day, and I received them 2 days later. Installed them this morning and the motor works like new! Thanks very much for the quality service and the user-friendly website. I'll be sure let my DIY friends know about your company.
