A bearing is a component made of one or two concentric rings that support a rotating shaft. At Ruedas Alex we use four different kinds of bearings depending on the required use for each wheel.
We will show you below the differences between a plain bearing, a ball bearing, a roller bearing and a tapered roller bearing.
This bearing is made of hardened balls held between an inner and an outer races. The majority of our ball bearing wheels use a double ball bearing. It is used for heavy duty applications where ease of movement is a prime concern.
One of its main advantages is the low friction movement. This bearing is sealed to prevent loss of lubrication and to keep out dust and dirt.
This is the simplest form of bearing, with a plain hub. Where is this bearing most commonly used? For light duties in domestic and transport castors but only for short distances and low speeds. They are impact and corrosion-resistant and require very little maintenance, apart from occasional lubrication.
Needle Roller bearing
This bearing for industrial wheels has steel rollers fitted into steel or plastic cages. One of its main advantages is the low rolling resistance, which makes it one of the best options for heavy loads.
This bearing is pre-greased, so there is no need for further lubrication unless used with heavy loads.
Tapered roller bearing
These are the sturdiest bearings and are used for very heavy duty applications. How do they work? Two bearings are mounted on both ends of the axle in an inverted position in front of each other.
This industrial bearing requires periodic lubrication, due to its higher friction movement compared to that of ball or roller bearings.
You already know the differences between our bearings, and now, we invite you to check our Ruedas Alex catalogue of industrial castors & wheels, with more than 4.000 references.
