Why are there different versions?
 
The bearing arrangement has to fulfil the principle of clarity. Furthermore, the bearing must ensure the defined control of the force flow. If it does, the bearing is considered statically determined. There are various bearing options, such as the fixed floating bearing and the double-sided floating bearing.
 

Fixed floating bearing:
the fixed bearing clearly positions the shaft in an axial direction. The fixed bearing must therefore absorb both radial and axial forces and guide them into the surrounding structure. This can basically be fulfilled by a single bearing. The floating bearing corrects parallelism errors minimally and offers thermal expansion capability, which means that the cable is not stressed.
 
Advantages of fixed floating bearing
► No axial clearance
► Non-critical shaft expansion (due to  such factors as temperature)
► Suitable for changing axial loads
► Clarity of forces applied 
 

Double-sided floating bearing:
in a double-sided floating bearing, the lead screw is not clearly fixed in the axial direction. This means that without stressing the bearing, mechanical or thermal differences in length can be absorbed, but the lead screw is not protected against drifting. This has to be considered in particular when dealing with positioning applications.
 
Advantages of double-sided floating bearings:
► Cost-effective
► Low design cost
► Non-critical shaft expansion (due to  such factors such factors as temperature) in the area of clearance
 
Disadvantages:
► Not clearly fixed in the axial direction
► Not suited to changing axial loads
► Only if axial clearance does not impair function

Versions 
 
Fixed bearing version (FL)
Depending on thread dimensions, this version has the clamping ring clamped into the lead screw itself or to the lead screw's outer diameter. For high helix lead screws, it is always the outer diameter that it is clamped to.
 
► Note: you can also choose a bearing block for your application that uses the measurement d1 for clamping onto the turned machined end.
 

Floating bearing (FL):
depending on the lead screw's dimensions, a machined end must be turned to the value d1. You can see below which dimensions this applies to. The floating bearing block merely supports the lead screw. This type does not prevent the lead screw from drifting.
 

Ball bearing type (BB):
this bearing block should always be used in case of highly dynamic applications, e.g. when a motor is involved
