2 Precision For TK Precision s, a wide array of precision-ground screw safts and ball screw nuts are available as standard to meet diversifi ed applications. Structure and Features Combinations of Various saft Diameters and Leads You can select te combination of a saft and a lead tat meet te intended use from te various nut types and te screw saft leads. Tose nut types include te return-pipe nuts, wic represent te most extensive variations among te series, te compact simple nuts and te largelead end-cap nuts. Standard-stock Types (wit Unfinised Saft Ends/Finised Saft Ends) are vailable Te unfi nised saft end types, wic are manufactured by cutting te standardized screw safts to te standard lengts, and tose wit fi nised saft ends, for wic te screw saft ends are macined to matc te corresponding te support units, are available as te standard. ccuracy Standards Compliant wit JIS (ISO) Te accuracy of te is controlled in accordance wit te JIS standards (JIS ).

3 Structure and Features of Offset Preload Type Simple-Nut Te Simple-Nut is an offset preload type in wic a pase is provided in te middle of a single ball screw nut, and an axial clearance is set at a below-zero value (under a preload). Te Simple-Nut as a more compact structure and allows smooter motion tan te conventional double-nut type (spacer inserted between two nuts).

4 Precision Simple-Nut Te preload adjustment wit Simple Nut Ball Screw is performed according to te ball. Tis eliminates te inconsistency in te contact angle, wic is te most important factor of te performance. It also ensures te ig rigidity, te smoot motion and te ig wobbling accuracy. Rotational Performance Conventional Double-Nut Type Te use of a spacer in te double-nuts tends to cause inconsistency in te contact angle due to inaccurate fl atness of te spacer surface and an inaccurate perpendicularity of te nut. Tis results in a non-uniform ball contact, an inferior rotational performance and a low wobbling accuracy. Since Simple-Nut is based on apreloading mecanism tat does not require a spacer, te overall nut lengt can be kept sort. s a result, te wole nut can be ligtly and compactly designed. 53 Dimensions Simple-Nut Double-Nut

Tis causes differential slip and spin to increase te rotational torque, resulting in an accelerated wear and a eat generation. Terefore, te accuracy deteriorates in a sort period. 2 point contact structure 4 point contact structure d2 d1 B Contact widt d2 d1 B Contact widt Ball rotational axis B d1 d2 Ball rotational axis Differential slip B π d1 π d2 B d2 Differential slip B π d1 π d2
6 Precision Types and Features Preload Type Model BIF Te rigt and te left screws are provided wit a pase in te middle of te ball screw nut, and an axial clearance is set at a below-zero value (under a preload). Tis compact model is capable of a smoot motion. Specification Table Model DIK Te rigt and te left screws are provided wit a pase in te middle of te ball screw nut, and an axial clearance is set at a below-zero value (under a preload). Tis compact model is capable of a smoot motion. Specification Table Model BNFN Te most common type wit a preload provided via a spacer between te two combined ball screw nuts to eliminate te backlas. It can be mounted using te bolt oles drilled on te flange. Specification Table Model DKN preload is provided via a spacer between te two combined ball screw nuts to acieve a below-zero axial clearance (under a preload). Specification Table
7 Model BLW Since a preload is provided troug a spacer between two large lead nuts, ig-speed feed witout by backlas is ensured. Specification Table No Preload Type Model BNF Te simplest type wit a single ball screw nut. It is designed to be mounted using te bolt oles drilled on te flange. Specification Table Model DK Te most compact type, wit a ball screw nut 70 to 80% of tat of te return-pipe nut. Specification Table Model MDK miniature type wit a screw saft of 4 to 14 mm and a lead of 1 to 5mm. Specification Table
8 Precision Model WF Tis for ig-speed feed acieves a DN value of 120,000 by using a new circulation structure. Since te nut outer and te mounting oles of tis model are dimensionally intercangeable wit te previous model WGF, model WGF can be replaced wit tis model. (WF1530, WF2040 and WF2550) Specification Table Models BLK/WGF Wit model BLK, te saft is equal to te lead dimension. Model WGF as a lead dimension 1.5 to 3 times longer tan te saft. Specification Table Square Nut Model BNT Since mounting screw oles are macined on te square ball screw nut, tis model can compactly be mounted on te macine witout a ousing. Specification Table
