Structure and FeaturesWith the Return-Pipe Nut, balls under a load roll around the circumference of the screw shaft,

while receiving an axial load on the ball raceways formed between the screw shaft and the ball

screw nut, then pass through the return pipe incorporated in the ball screw nut and circulate

back to the loaded area, thus to achieve infinite motion. Being the most common type is the

series with the broadest range of variations, it can be used in a wide array of applications.

Standard-LeadPrecisionBallScrew

Types and FeaturesOffset-Preload Type Model BIF

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). This compact

model is capable of smooth motion.

The most common type with a preload pro-

vided via a spacer between the two com-

bined ball screw nuts to eliminate backlash.

It can be mounted using the bolt holes

drilled on the flange.

Double-nut Preload Type Model BNFN

The simplest type with a single ball screw

nut. It is designed to be mounted using the

bolt holes drilling on the flange.

Since mounting screw holes are machined

on the square ball screw nut, this model

can compactly be mounted on the machine

without a housing.

Non-preload Type Model BNF Non-preload Type with a Square Ball Screw Nut Model BNT

Note The rigidity values in the table represent spring constantseach obtained from the load and the elastic displacementwhen providing a preload 10% of the basic dynamic load rat-ing (Ca) and applying an axial load three times greater thanthe preload. These values do not include the rigidity of the componentsrelated to mounting the ball screw nut. Therefore, it is normal-ly appropriate to regard roughly 80% of the value in the tableas the actual value.If the applied preload (Fa0) is not 0.1 Ca, the rigidity value (KN)is obtained from the following equation.

Note The rigidity values in the table represent spring constantseach obtained from the load and the elastic displacementwhen providing a preload 10% of the basic dynamic load rat-ing (Ca) and applying an axial load three times greater thanthe preload.These values do not include the rigidity of the componentsrelated to mounting the ball screw nut. Therefore, it is normal-ly appropriate to regard roughly 80% of the value in the tableas the actual value.If the applied preload (Fa0) is not 0.1 Ca, the rigidity value (KN)is obtained from the following equation.

Note The rigidity values in the table represent spring constants eachobtained from the load and the elastic displacement when providinga preload 10% of the basic dynamic load rating (Ca) and applyingan axial load three times greater than the preload. These values do not include the rigidity of the components relatedto mounting the ball screw nut. Therefore, it is normally appropriateto regard roughly 80% of the value in the table as the actual value.If the applied preload (Fa0) is not 0.1 Ca, the rigidity value (KN) isobtained from the following equation.

whereNote The rigidity values in the table represent spring constantseach obtained from the load and the elastic displacementwhen providing an axial load 30% of the basic dynamic loadrating (Ca). These values do not include the rigidity of thecomponents related to mounting the bal l screw nut.Therefore, it is normally appropriate to regard roughly 80% ofthe value in the table as the actual value.If the axial load (Fa) is not 0.3 Ca, the rigidity value (KN) isobtained from the following equation.

whereNote The rigidity values in the table represent spring constantseach obtained from the load and the elastic displacementwhen providing an axial load 30% of the basic dynamic loadrating (Ca). These values do not include the rigidity of thecomponents related to mounting the bal l screw nut.Therefore, it is normally appropriate to regard roughly 80% ofthe value in the table as the actual value.If the axial load (Fa) is not 0.3 Ca, the rigidity value (KN) isobtained from the following equation.
