Bearings and Bushings
When purchasing bearings and bushings ask yourself the following:
- How do you know the will-fit bearings and bushings have been purchased from a trustworthy manufacturer?
- Do you have the confidence in the bearings and bushings once installed on your Toro machine?
- Are you getting the exact, high-quality bearing designed specifically for the application?
With Toro there's absolutely no question that the bearing or bushing you order is designed for the specific application.
There are two types of bearings Toro uses in most of their machines depending upon the application: Sealed and Unsealed. Sealed bearings require no maintenance while unsealed bearing need to be greased on a regular basis.
As with all our parts, Toro conducts continuous and extensive bearing tests to assure they will not fail for specific applications and mechanisms. The difference between Toro and will-fitters is not so much the bearing themselves but how they are protected.
That's where the big difference is. Toro bearings and bushings are designed and manufactured to stand up too much more load capacity and speed than they are specifically designed for to provide an extra margin of safety.
Bearings most often fail because of contamination - either water or dirt. Period.
Bushing and bearing specifications are based on a PV ratio (Pressure versus Velocity). Different loads and speeds determine which type of bearing or bushing will work best for a particular application.
Bearings are generally used for applications that have no impact or shock. Bushings are used for applications that feature more shock (such as caster wheel assemblies).
Bushings are normally installed in specific areas for three reasons:
- A bearing would be too expensive.
- Load perimeters might be too heavy for a bearing to support.
- The mechanism requires a reciprocating motion.
