Allowable Side Load

JWB・JWH(Ball screw type ・High lead ball screw type )

Ball screw type and high-lead ball screw type cannot withstand loads other than those in the axial direction.

If side load applies, make consideration so that it does not directly apply the jack by installing a guide as shown below.

Guide

JWM(Trapezoidal screw type )

Guides are typically used for trapezoidal screw types as shown in the diagram below. However, if the shaft projection distance (L) beyond the housing surface is relatively short (when the jack is stationary), a certain amount of side load is acceptable.

Note) L represents the distance of screw shaft projection that affects side load. (Not a stroke distance )
