Series R118

Here you can configure your e-chain system? individually. All entries and changes are taking over to the part list which is situated at the end of the page.

Series R118, tube openable along the outer radius, from both sides

1. Effective swarf protection, even hot hot swarf
2. Smooth chip-repellent outer contour
3. Double stop-dog system for large unsupported length
4. Side opening lids and covered pin/bore connection
5. Lateral gliding surfaces for side-mounted operation
6. Lids openable along inner or the outer radius
7. KMA mounting bracket with attachment options from any side
8. Good ratio of outer to inner dimensions

R118 Series is suitable for the following types of applications:

Vertical: Hanging applications, standing applications
Horizontal: Unsupported applications �� 1.2 m
Circular movement: Rotating applications possible, may require machining (machining rework is always required from rotation angles of 180��)

When to use Series R118

If a chip-repellent e-tube with 21?mm inner height is required
If an inner width up to 100mm is required
For unsupported lengths up to 1.2m and fill weights up to 1.5kg/m
If an affordable e-tube is required that is openable from the inside or outside
If front attachment is required
For small bend radii

When not to use Series R118

For quiet run and smaller pitch
Energy tubes E2, Series R48

The required clearance height HF = H + 25 mm , which should be observed in all types of applications. Please contact us if you have particularly confined space requirements.
** The calculated length corresponds to the chain length without mounting brackets.

A=moving end, B=fixed end
Pitch: 30.5 mm
Chain links per m: 33
Travel: S
Tube length = S/2 + K

Unsupported length

The unsupported length depends on fill weight
X axis: unsupported length in m FLB/FLG
Y axis: fill weight in kg/m
Lower scale: travel S in m
FLB = unsupported with permissible sag
FLG = unsupported with straight upper run
