The object of roller bearings (and ball bearings) is the substitution of pure rolling motion for plain sliding friction.
Rigid single row roller journal bearing.- Basic type of roller bearing commonly used for heavy radial loads. No thrust
can be taken, for although one track of the race is lipped, the other race is plain and the bearing does not locate the shaft
axially.
Lipped roller bearing.- This bearing has either one or two lips on both races and will locate axially in one or both
directions but will not take appreciable thrust.
Loose side plate bearing.- This type of bearing has a lip on one side and a loose plate on the other to simplify
assembly ans dismantling of components and to locate the shaft axially.
Aligning roller bearing.- To correct initial misalignment but not deflection under load.
Needle roller bearing.- Provide a small diameter, light bearing load for assemblies in which space and weight
are restricted.
Taper roller bearings.- These bearings will take appreciable radial loads and thrust loads in one direction (single row)
or both directions (double row). Single row bearings can be used in pairs to take thrust in both directions. This arrangement has the
advantage that by providing adjustment to the clamping of the inner races the internal clearance of the bearings can be regulated
while also providing a means of taking up wear.
Spherial roller bearing.- For applications where high load capacity is required together with the capability to absorb
slight deflections when rotating.
This bearing provides the needle roller bearing with a means of taking axial loads, thus enabling the combination of small outside diameter and the facility of taking thrust in one direction.
