Compared to ball screws, lead screws are less susceptible to dirt. However, the accumulation of dirt on the screw should of course be avoided. If dirt works its way into the nut, wear usually increases. In combination with lubrication, this can lead to the dirt particles combining with the lubricant and creating an “abrasive paste”.<\/p>\n
Ideally, the spindle should be completely protected with a bellows or another design measure.<\/p>\n
For applications where this is not possible for reasons of space or cost, the use of a wiper for trapezoidal threaded spindles is a conceivable alternative.
\njunaspin wiper for trapezoidal threaded spindles
\nCast metal wiper with rubber wiper lip<\/p>\n
Material:
\nWiper made of NBR70 (+-5 Shore)
\nOther sealing materials (Cr, FKM, EPDM, VMQ etc.) on request<\/p>\n
Housing made of steel
\nOther housing materials (aluminum, V2A, V4A) on request<\/p>\n
junaspin will be happy to help you select a wiper. Based on our experience, we can also assess whether the use of a dry-running system is possible in your application.<\/p>\n","protected":false},"excerpt":{"rendered":"
