SFE1616 One Turn Feed Screw

Product Details

The model number describes two different dimensions. The first "16" is the nominal screw diameter; the second is the lead. They must both appear in an inquiry because a 16 mm shaft can also be produced with other travel-per-revolution values.

 

This assembly uses one flanged ball nut. Recirculating balls transfer the shaft rotation into nut movement, while seals fitted at both nut ends help keep grease inside and loose contamination away from the return path.

 

The page does not state a preload grade, axial clearance or accuracy class. These values cannot be inferred from the SFE1616 designation and must be added separately when they matter to the machine.

 

Product Description

Linear feed can be estimated directly from motor speed:

Linear speed = screw speed × 16 mm

 

At 1000 rpm, the calculated feed is 16,000 mm per minute. This is only a motion ratio, not the permitted operating speed. Screw length, support arrangement, shaft vibration, load and acceleration may impose a lower limit.

 

The same relationship also affects command resolution. Before considering gearbox ratio or electronic subdivision, one degree of screw rotation corresponds to approximately 0.044 mm of linear travel. Control settings should be calculated around the actual motor and transmission arrangement.

 

Shaft-end machining is not defined by the 1616 code. Bearing journals, locknut threads and the coupling end must follow the selected support units.

 

Features

16 mm Feed Per Revolution

The equal diameter and lead make SFE1616 suitable where a relatively large carriage movement is required from each motor revolution.

Single Nut Layout

One nut keeps the assembly shorter than a double-nut arrangement. Required clearance or preload must be stated separately.

Sealed Nut Ends

Dust seals are fitted at both ends of the nut to protect the internal ball-return area and retain lubricant during operation.

 

FAQ

What does SFE1616 mean?

It identifies a 16 mm nominal screw diameter and a 16 mm lead.

Is 16 mm the thread pitch or total travel?

It is the nominal linear movement produced by one complete screw revolution.

Is this a double-nut ball screw?

No. The page identifies it as a single-nut assembly.

Does the model number define the accuracy grade?

No. Accuracy, preload and axial-clearance requirements must be specified separately.

Can the shaft ends be supplied ready for installation?

We build to customer drawings under OEM/ODM, and accept orders as small as a single piece for standard sizes.
