Fixed side End-journal profile and dimension are standardized, so KSS Compact Support-Unit can be installed.
●Accuracy Grade & Axial play
Whole threaded type is a high cost performance type and end-journal machining is available in accordance with your request. The Axial play is set at 5um or less, but Zero backlash is possible based on your request.
The grade of PSR/PSRT series（Standardized Precision Rolled Ball Screws）is C5（JIS B-1192）. Axial play of this series is 0.005mm or less, but zero backlash（pre-load）type is available by your request. ●Material & Surface hardness
The material and hardness of PSR/PSRT series
（Standardized Precision Rolled Ball Screws）are as follows.
Products
We have 2 types of Precision Rolled Ball Screws, which are Integrated type with larger journal（PSRT）and whole threaded length type（PSR）. Precision Rolled Ball Screws （PSR series ）

A335 A337 A336 A338 A341 A342
For Integrated end-journal type, Fixed side end-journal can be set larger than nominal diameter of Screw Shaft, so there is no need to use Collar by press fit.
Since supported-side end-journal is unfinished, it is possible to do additional end machining with your requested thread length.

We have 2 types of Precision Rolled Ball Screws, which are Integrated type with larger journal and whole threaded type. So it provides wide variety of design choices.

Shaft dia.
The conventional type of Rolled Ball Screws can reach the Accuracy grade of Ct10 or Ct7. KSS newly developed the high grade accuracy of Rolled Ball Screw, which can achieve JIS C5 grade.

Note : Material Name is based on JIS : Japanese Industrial Standards.
●Lubrication
Standardized Precision Rolled Ball Screws whole threaded length type（PSR Series）will be supplied with anti-rust oil. This oil is not lubricant, when Ball Screw operates, lubricant should be applied. If there is no specific instruction, KSS would recommend our original grease（MSG No.2）as standard lubricant. Please feel free to contact us. ●Others
PSR/PSRT series（Standardized Precision Rolled Ball Screws）provide 3 types of Ball Nut profile. Return-plate style and End-cap style are our standard. In addition Internal-Deflector style as Compact Ball Nut is also in stock. So you can pick one of them based on your design.

Model number notation of PSR type（whole threaded type）is as follows. Please designate end-journal profile with your simple sketch.
It will be the customized if you need special specifications like below, please ask KSS representative. 1）Non‐standard profile or dimension on Shaft end‐journal. 2）Non‐standard profile or dimension on Ball Nut or Flange. 3）Zero backlash（Pre‐loaded）type Ball Screw. 4）Longer length of Ball Screw Shaft than standard product. Fig. A-27：Nut Flange direction
X：Fixed side
●Note 1）Zero backlash is possible by your request, please ask KSS representative. 2）We recommend additional end-journal machining is done by KSS.
We do not guarantee accuracy after re-works done by other than KSS. 3）Please send us drawing with end-journal profile when you request end-journal maching. 4）Additional machining is not applied to the Nut. Please design flange configuration according to our standard dimension. 5）In Ball Screws use, lubricant should be applied on them. Please note that anti-rust oil is not lubricant.
A-type：Free
B-type：Journal with snap ring groove
Y：Supported side C-type：Journal only D-type：Other than the above
●Note 1）The detail of end-journal dimension for each size is shown from next page. 2）KSS does not make additional Nut machining. 3）The specification is subject to change without notice. 4）If the other configuration except（A,B,C）is requested, please contact KSS. 5）KSS will not be responsible for quality, in case re-work is done by other than KSS.

Fixed side End-journal profile and dimension are standardized, so KSS Compact Support-Unit can be installed.
●Accuracy Grade & Axial play
Whole threaded type is a high cost performance type and end-journal machining is available in accordance with your request. The Axial play is set at 5um or less, but Zero backlash is possible based on your request.
The grade of PSR/PSRT series（Standardized Precision Rolled Ball Screws）is C5（JIS B-1192）. Axial play of this series is 0.005mm or less, but zero backlash（pre-load）type is available by your request. ●Material & Surface hardness
The material and hardness of PSR/PSRT series
（Standardized Precision Rolled Ball Screws）are as follows.
Products
We have 2 types of Precision Rolled Ball Screws, which are Integrated type with larger journal（PSRT）and whole threaded length type（PSR）. Precision Rolled Ball Screws （PSR series ）

For Integrated end-journal type, Fixed side end-journal can be set larger than nominal diameter of Screw Shaft, so there is no need to use Collar by press fit.
Since supported-side end-journal is unfinished, it is possible to do additional end machining with your requested thread length.

We have 2 types of Precision Rolled Ball Screws, which are Integrated type with larger journal and whole threaded type. So it provides wide variety of design choices.

Shaft dia.
The conventional type of Rolled Ball Screws can reach the Accuracy grade of Ct10 or Ct7. KSS newly developed the high grade accuracy of Rolled Ball Screw, which can achieve JIS C5 grade.

Note : Material Name is based on JIS : Japanese Industrial Standards.
●Lubrication
Standardized Precision Rolled Ball Screws whole threaded length type（PSR Series）will be supplied with anti-rust oil. This oil is not lubricant, when Ball Screw operates, lubricant should be applied. If there is no specific instruction, KSS would recommend our original grease（MSG No.2）as standard lubricant. Please feel free to contact us. ●Others
PSR/PSRT series（Standardized Precision Rolled Ball Screws）provide 3 types of Ball Nut profile. Return-plate style and End-cap style are our standard. In addition Internal-Deflector style as Compact Ball Nut is also in stock. So you can pick one of them based on your design.

Model number notation of PSR type（whole threaded type）is as follows. Please designate end-journal profile with your simple sketch.
It will be the customized if you need special specifications like below, please ask KSS representative. 1）Non‐standard profile or dimension on Shaft end‐journal. 2）Non‐standard profile or dimension on Ball Nut or Flange. 3）Zero backlash（Pre‐loaded）type Ball Screw. 4）Longer length of Ball Screw Shaft than standard product. Fig. A-27：Nut Flange direction
X：Fixed side
●Note 1）Zero backlash is possible by your request, please ask KSS representative. 2）We recommend additional end-journal machining is done by KSS.
We do not guarantee accuracy after re-works done by other than KSS. 3）Please send us drawing with end-journal profile when you request end-journal maching. 4）Additional machining is not applied to the Nut. Please design flange configuration according to our standard dimension. 5）In Ball Screws use, lubricant should be applied on them. Please note that anti-rust oil is not lubricant.
A-type：Free
B-type：Journal with snap ring groove
Y：Supported side C-type：Journal only D-type：Other than the above
●Note 1）The detail of end-journal dimension for each size is shown from next page. 2）KSS does not make additional Nut machining. 3）The specification is subject to change without notice. 4）If the other configuration except（A,B,C）is requested, please contact KSS. 5）KSS will not be responsible for quality, in case re-work is done by other than KSS.
