When purchasing bearings you can trust that Toro has the integrity of your specific piece of equipment in mind. You can have confidence that a Toro bearing will perform as it was designed to do to keep your equipment running for years. Toro conducts continuous and extensive bearing tests to assure they will not fail for specific applications and mechanisms. That’s where the big difference is between Toro and will-fitters. Toro bearings are designed and manufactured to stand up to much more load capacity and speed than they are specifically designed for to provide an extra margin of safety.
