Series R118

Here you can configure your Energy Chain System® individually. All entries will be copied to the Bill of Materials shown at the bottom of this page.

Series R118 - snap-open on both sides in the outer radius

1. Effective chip protection, even against hot metal chips
2. Smooth, chip-repellent exterior
3. Double stop dog for strong unsupported length
4. Snap-open from the side, covered pin/bore connection
5. Lateral glide surfaces for side-mounted operation
6. Snap-open lids along the inner or outer radius
7. Universal KMA mounting brackets with attachment capability on all sides
8. Space-efficient with optimized ratio of inner to outer dimension

Inner widths Bi: 0.79 up to 3.94 (20 - 100 mm)
Bending radii R: 2.48 up to 7.09 (63 - 180 mm)
Pitch: 1.2 (30.5 mm) per link = 11 links/ft (33/m)

When to use Series R118

If snap-open accessibility along inner or outer radius is required
If price is an issue
If flush attachment is required

When not to use Series R118

If accessibility along the sides of the radius is required
System E4/100, Series R760
For smoother running and smaller pitch
Energy tubes E2, series R48

Unsupported length

Dependency of the unsupported length on the additional load
X axis: Unsupported length in ft FLB/FLG
Y axis: Additional load in lbs/ft
Lower scale: Length of travel S in ft
FLB = unsupported with permissible sag
FLG = unsupported with straight upper run
