Data and Dimensions

Lightweight Beam

The DLS3 lightweight beam is half the weight of the standard version. This is a valuable benefit for any system, such as the Y-axis of a multi-axis system and any cantilever axis, where the beam moves. It has the same external dimensions as the standard beam, but is less stiff. This will increase deflection which may be significant in long unsupported spans. See page 19 for deflection calculations.

The lightweight beam is compatible with the standard fixing clamps and both quick-fit and heavy duty T nuts, although a reduction in the material thickness means that the quick-fit T nut can bruise the T slots if fully tightened. It is therefore recommended that the alternative heavy duty T nuts are used for high load fixing.

Fixing Clamps

75 (DFC-3-L)

The fixing clamps are designed to hold the DLS beam or end units to a flat surface. The long clamps have two holes spaced to suit the customer mounting holes on the appropriate size of carriage (see application example 1 on page 7.)

The DFC-3-S/L (for use with DLS3) are counterbored to suit M6 socket cap head screws and the DFC-4-S/L (for use with DLS4) are counterbored to suit M8 socket cap head screws.

In many applications (e.g. on page 7) it is necessary to connect two parallel DLS axes together to work in tandem. In these cases a drive shaft should be specified. The drive shaft has been specially selected to have excellent torsional stiffness to ensure that "wind up" of the shaft and the consequent following error of one carriage to the other is minimized. The drive shaft is also designed to enable it to be fitted with both DLS units in position, as the shaft can be radially removed from the couplings without the need to separate the components axially.

In high speed applications where long shafts are used it may be necessary to support the shaft with a pillow block type bearing to prevent "whipping". See the table below for when to specify.
