| Finished Shaft Ends Model BNK |
A Ball Screw with a screw shaft end standardized according to the support unit. |
| Offset Preload Model BIF |
With this Ball Screw, the right and left screws are provided with a phase in the middle of the ball screw nut to achieve a below-zero axial clearance (under a preload). |
| Slim nut Model DIK |
A deflector-type Ball Screw in which the right and left screws are provided with a phase in the middle of the ball screw nut, and an axial clearance is set at a below-zero value (under a preload). |
| Rotary nut Model DIR |
A nut-rotating Ball Screw in which a defector-type ball screw nut is integrated with a support bearing. |
| Double-nut Preload Model BNFN |
The most common type with a preload provided via a spacer between the two combined ball screw nuts to eliminate backlash. |
| Slim nut Model DKN |
A deflector-type Ball Screw in which a preload is provided via a spacer between the two combined ball screw nuts to achieve a below-zero axial clearance (under a preload). |
| Large Lead Model BLW |
Since a preload is provided through a spacer between two large lead nuts, this Ball Screw model is capable of high-speed feed without backlash. |
| Single nut Model BNF |
The simplest type with a single ball screw nut. |
| Square Nut Model BNT |
Since mounting screw holes are drilled on the square ball screw nut, this model can compactly be mounted on the machine without a housing. |
| Slim nut Model DK |
ボThe most compact Ball Screw with the outer diameter of its ball screw nut being 70 to 80% of that of the return-pipe type. |
| Miniature Model MDK |
A miniature type with a screw shaft diameter of φ4 to φ14 mm and a lead of 1 to 5mm. |
| Miniature Model MBF |
A miniature type with a screw shaft diameter of φ4 to φ14 mm and a lead of 1 to 4mm. |
| Large Lead Model BLK |
With this Ball Screw, the shaft diameter is the same as the lead dimension. |
| Super Lead Model WGF |
With this Ball Screw, the lead length is 1.5 to 3 times greater than the shaft diameter. |
| Large Lead Rotary nut Model BLR |
A nut-rotating ball screw that has an integrated structure consisting of a ball screw nut and a support bearing. |
