Rubber Shield
Bearing shields are traditionally hard plastic or metal, but modern innovation has introduced the rubber shield as the most popular choice. The rubber creates an excellent seal against moisture, and will not crack or corrode with age. They are also easy to remove and re-install for cleaning and lubrication.
Nylon Retainer
A retainer is for keeping the balls in place at equal distance from each other. While there are a few different types of retainers in the bearings market, all Rush bearings use the "TW" type molded nylon cage. Nylon retainers are superior to metal types for several reasons. They are are lighter than metal, and have the flexibility to withstand impact, i.e not crack or deform under pressure. They are heat resistant and do not corrode from dirt and moisture. Lastly, nylon retainers have little friction in comparison to metal retainers and and therefore are the most suitable for high speeds.
Inner and Outer race, or, Casing
Our casings are made of titanium coated steel or stainless steel, depending on the line of bearing. We only use the highest grade steel available, so you won't have to worry about warps or dings. The deep grove inside the outer race is specially designed to support high load and hard impact. Because of the precise build of our bearings, the inner race and outer race act as one component (though not connected) even when the retainer is removed, holding the balls securely in place. This is especially helpful for those meticulous people who like to remove the retainer when cleaning, as the bearings will stay intact and not roll of the table and into oblivion.
7 balls
Whether steel, stainless steel or ceramic, all of our bearing balls are polished to perfection with a micro-finish and then lubricated with a specialized combination of lube and grease, so they're ready to roll right out of the package.
