I was leery because of online reviews but was pleasantly surprised.

I received quality parts quickly at a great price and without hassle. I had read some bad reviews so I had suspicions. More good reviews than bad so I gave them a try and was not disappointed. Thanks.

Fair price and fast free shipping! Most other sites charge more for the shipping than the cost of the items. Will use this company for future bearing purchases.

Have purchased the Isostatic sintered bronze items instead of Symmco and they work just as well, but cost less $.

How do I choose the right type of bearing for my application?

Start with the load and how it’s applied. You need to know if you’re dealing with radial loads, axial loads, or a mix of both. Then look at speed, operating environment, and space constraints. For example, ball bearings are great for high speed and lighter loads, while roller bearings handle heavier loads but usually at lower speeds. If there’s contamination, moisture, or heat involved, you may need sealed bearings or specific materials. In most cases, the right choice comes down to matching load type, speed, and environment to the bearing design.
