Quick Install Ball Screw Assemblies

How to select a configured ball screw assembly: Identify the minimum required parameters and answer a couple basic questons: a. Load – Amount of force that will be applied axially to a ball screw b. Speed – RPM or linear travel rate c. Mounting requirement – base or flange mount d. Life requirement e. Inch or metric? f. Is backlash acceptable?

Here is an example to demonstrate the ease and simplicity of the process: For these given values: a. Load = 1,500 lbs b. Speed = 500 in/min and 1,200 RPM maximum c. Mounting = Flange supports required d. Life = 1 million inches of travel e. Travel length = 48 inches f. Lash = Backlash is acceptable Step 1 – Select ball screw diameter based on load capacity and mounting configuration

Go to Table 1 and select the FK-FK column and find the cell that exceeds the load requirement. In this example, a Ø1.000 screw has a rating of 1,875 lbs and is acceptable.

Step 2 – Select lead and ball nut p/n

Since lead = linear rate / RPM, the lead is 500 in/min / 1200 rotations/min = .417 inches / rotation. Select a lead from Table 2 that is greater than the calculated amount. In this example, select .500 lead which equates to 500 / .500 = 1,000 RPM. Since backlash is acceptable in this application, choose a 1.000 x .500 standard ball nut (p/n 8110-448-022).

Step 3 – Verify life requirement of ball nut and end support.

Use Table 3 to find dynamic capacity rating of the ball nut (Cam = 3,950 lbs) and the end support selection (Cam = 2,270 lbs).



Calculate the life of the ball screw assembly using standard L10 life equation. L10 = (Cam/Load)3, L10 = (3,950/1,500)3 = 18.3 million inches of travel = 36.6 million revolutions.



Calculate the life of the end supports using standard L10 life equation. L10 = (Cam/Load)3, L10 = (2,270/(1,500/2))3 = 27.7 revolutions.

Step 4 – Verify screw meets critical speed limitation

Use critical speed graph for FK-FK support and verify that assembly is below the critical speed curve. Use calculated RPM (1,000) and travel length (48in) and verify that the intersect point is below and to the left of the Ø1.000 curve.

Step 5 – Build configured part number

The configured part number for this example is therefore: 1000x0500S 48.000 FK-FK SSFW

Step 2 - Select lead

• Select preload if zero lash is required • Select lead based on required speed • Linear speed (in/min) = (RPM) x (Lead)

Step 3 - Verify life requirement of ball nut and end support

• Calculate life of ball screw assembly using L10 = (Cam / Load)3 million inches • Calculate life of end supports using L10 = (Cam / Load per support)3 million revolutions i.e. : Divide load by 2 if using 2 BK-BK, FK-FK, MK-BK, or WK-WK.

Did you know… • Ball screw selection needs to be based on load rating of the ball screw AND the end supports. The end supports are typically the limiting component in regards to axial capacity. • Ball screws are case hardened to a minimum of 56 HRC and typically above 60 HRC. Machining of the ends requires specialized tooling and processes to save tool life, and prevent excessive run-out and poor surface finishes. • Ball screw components are typically shipped with only a rust preventative coating. Improper lubrication of ball screws can reduce life by 90%. • Improper transfer of the ball nut unto the screw can result in trapped balls that can destroy a ball screw in minutes. • Improper transfer of the ball nut unto the screw can result in lost balls that can reduce the life of the assembly. • Improper installation of bearing supports may damage seals and angular contact bearings of the end supports causing rough operation and premature failure. • Poor system alignment is among the leading causes of ball screw failure.

Thomson advantages and benefits… • Engineered systems to meet demanding applications. • Full spectrum of tools to help select the correct product. • Experienced assemblers trained to correctly build ball screw systems. • Quality components that will perform and last. • Plug-and-play assemblies ready to be installed in your machine.
