Our latest Slideway improvement...

It's more compact!

The HV Type is a major and compatible improvement of our SV Type.

• Reduces unit size while keeping the equivalent performance
• Improves durability

Seven Critical Steps Before You Order

1. Pre-select the size and number of linear systems

Pre-select the size and number based on balance of machinery and other equipment as well as past experience.

2. Calculate applied load

Calculate applied load on each system. Calculate average variable load.

Refer to Engineering Information [ Method for Determining Applied Load ] ]

3. Determine static load

Determine basic static load rating and allowable static moment by applying static safety factor.

* When neither a point to be checked nor a calculation result fulfills conditions in this stage, it is necessary to return to [2:Decide system type] and to do selection again.

Refer to Engineering Information [Allowable Load]

4. Compute rated life

Checking Hardness Coefficient, Temperature Coefficient, Contact Coefficient and Applied Load Coefficient, please compute the rated life in cosideration of the applied load (No.4) and the basic dynamic load rating (Pre-selection).

* When conditions are not fulfilled as compared with [1:Determine the application conditions], it is necessary to return to [2:Decide system type] or [3:Pre-select the size and number of linear systems] and to do selection again.

Refer to Engineering Information [Life].

5. Determine preload and accuracy

Determine preload and accuracy based on the operating conditions. (refer to each product description for preload and accuracy)

* When neither a point to be checked nor a calculation result fulfills conditions in this stage, it is necessary to return to [2:Decide system type] or [3:Pre-select the size and number of linear systems] and to do selection again.

Refer to Engineering Information [Rigidity and Pre-Load]

6. Select Lubrication and dust prevention method

Select lubrication and dust prevention method. (seals, bellows, covers)

Refer to Engineering Information [Operating Environment]

7. Confirm the space needed in the equipment

Confirm space and installation dimensions in consideration of the machine size and ease of maintenance.

* When neither a point to be checked nor a calculation result fulfills conditions in this stage, it is necessary to return to change system type or the size and number of linear systems.

If you have any questions, please contact NB.

See why the interior corners of your slidewaymounting surfaces need to be forgiving ...

For the shoulder shape, provide relief at the corner as shown, so that it does not interfere with the reference corner of the rail. See Page G-7

Flange Bush Speeds Mounting &

Eliminates Bulky Housings

NB’s round, square or two-side cut Flange Slide Bush lines offer the best of both worlds - the benefits of a slide bush with the mounting ease of a flange. When your application calls for ease of assembly, you can select a completely integrated system. The flange bush product lines include single, double-wide, or center mount configurations. Flange types are available in inch, Asian or European metric dimensions. 

There is tremendous variety of flange bush combinations in inch dimensions that are immediately available. There are three shaft grades. They have diameters ranging from .125 - 2 inches. Slide bush lengths range from .5 - 8 inches.

NB can fulfill your orders faster because we only use air transport – not ships.
