Customized Products
In order to meet the needs of customer's requested design, we offer customized products.
To reduce design process at customer, each Nut type is standardized.
*Single Nut with Flange
|
It is most simple Single Nut type. Normally Ball Screws are used with small Axial play, but using oversized Balls allows for the application of light preloading and eliminates backlash (only Precision grade). Nut should be mounted using bolt holes in Flange. FBS (Return-plate), FKB (Internal-deflector), FDB (End-deflector), FEB (End-cap) circulation system can be distinguished. |
|---|
*Sleeve type Single Nut
|
It is Cylindrical Single Nut which is compact. Alike Single Nut with Flange, Axial play can be eliminated (only Precision grade). The Nut should be mounted by clamping on the keyway on the Nut outer and Nut end surface. |
|---|
*Single Nut with M-thread
|
The Cylindrical type with M-thread at the Nut end. The Nut should be mounted using M-thread. It is suitable for mounting with cylinder. |
|---|
*Square type Single Nut
|
The square Nut is finished with a large mounting face parallel to the Nut center. Nut itself has Housing function. This allows for a more compact design compared to Flange type. |
|---|
*Double Nut with Flange
|
A Spacer is inserted between the two Nuts to eliminate Axial play. Preloading can also be applied to increase Nut Rigidity. The Nut should be mounted using bolt hole in Flange. |
|---|
*Sleeve type Double Nut
|
This uses two Cylindrical Nuts with a Spacer inserted between them to apply Preload. The Nut should be mounted by clamping on the Keyway on the Nut outer and Nut end surface. |
|---|
*Bi-directional Nut with Flange
|
Since there are both Right-handed thread and Left-handed thread on a Shaft, it has Bi-directional function. Single Nut with Flange type is standardized, but it is also possible to manufacture Sleeve type Nut. In addition, absolute position control for both Nuts is available. |
