[!] Key materials are not included.

[!]Specify an alteration position to be 2 mm or more away from the stepped part. (Refer to the diagram in Caution (1))
[!] When adding multiple alterations, there must be 2 mm or more clearance between each machined part. (Refer to the diagram in Caution (2))
[!]When flat machining, wrench flats, square chamfering and keyway alterations are combined with each other, their orientations will be random. (Refer to the diagram in Caution (3))
[!] Do not specify multiple alterations in such a way that they overlap with each other in the rotating direction on the same shaft. (Refer to the diagram in Caution (4))
[ ! ] When two or more alterations are specified on a shaft, they may not be machined due to correlation.

Caution (1)
Specify the alteration portion to be 2 mm or more away from the stepped part
.
Lead Screws - For Support Units: Related Image
Caution (2)
2 mm or more is required for the clearance between multiple alterations
.
Lead Screws - For Support Units: Related Image
Caution (3)
When the multiple alterations are combined with each other, their orientations are random and thus, are not always aligned in a linear arrangement. (One example of this is shown in the diagram below.) 
Lead Screws - For Support Units: Related Image
For Alterations A and B added to the same shaft, as shown in the diagram above, their orientations are random and thus, there are some cases where they are not aligned in a linear arrangement.
Caution (4)
Do not specify multiple alterations in such a way that they overlap with each other on the same shaft.

Outline and specifications

App. Example

■Slide Base Transfer Unit
■Recommended Configuration
This unit allows the slide base for workpiece/fixture loading to be position-adjusted
by manually rotating its lead screws. A dedicated lead screw, bearing unit and stopper clamp are combined
in a set.
The unit can support radial and axial loads, and can be constructed more economically in a compact manner
. Also, position indicators can be easily mounted.
