Question:<\/strong><\/p>\n

Dear MISUMI Engineering Team,<\/p>\n

What is the difference in the single and double type? Why is the “Maximum Stroke” so much different between the two types?<\/p>\n

Thank you,<\/p>\n

Eric<\/p>\n

Answer<\/strong>:<\/p>\n

Hello Eric,<\/p>\n

I assume you are referring to Stroke bushings.\u00a0Typically our linear bushings<\/a> are designed with a return mechanism, where balls recirculate back into the system which allows limitless stroke.<\/p>\n

The advantage of using double bushings is having more ball bearings (double amount) in contact with shaft. This allows for great improvement of static and dynamic load, drastically increases your moment load ratings and system\u2019s stability.<\/p>\n

The construction of a Stroke Bushing is very different.<\/p>\n

There is no ball return mechanism. The balls are embedded into a sleeve and they roll on the shaft\u2019s outside diameter and the housing\u2019s inside diameter while the sleeve is suspended between the two, providing solid lubrication to the ball bearing .<\/p>\n

\"Sleeve\"<\/a>

So if the shaft is stationary, while moving the housing, the sleeve with bearing balls will also move, but at different (slower) rate in relation to the shaft, but the sleeve\u2019s travel\u00a0 will be limited by surface length of the housing\u2019s Inside Diameter.<\/p>\n

Please, see the single and double Stroke Bushings<\/a>:<\/p>\n

Again, by having double amount of ball bearings \u00a0you will still benefit from better load ratings, but it will limit your stroke. I\u00a0hope I answered\u00a0your questions,\u00a0but feel free to comment below or contact us at engineering@misumiusa.com<\/a> with any additional questions!<\/p>\n

Thank you,<\/p>\n
