The Chainflex® class is composed of 3 parts:
Requirements Travel distance Resistance to oil
1 up to 7 1 up to 4 1 up to 4
Requirements
1: Flexible cables
2: Highly flexible cables
3: Chain-suitable cables without special
structure (e.g. stranding in layers) for
the use in E-Chains®.
4: Cables with special structure for the
permanent move in E-Chains® for
medium requirements and radii from
7,5 x d, speed up to 3 m/s
5: Cables for the permanent move in
E-Chains® for high load requirements
and radii from 6,8 x d, speed up to
10 m/s
6: Cables for the permanent move in
E-Chains® for highest load requirements
and radii from 5 x d, speed up
to 10 m/s
7: Cables for the permanent move in
E-Chains® for highest load requirements
and smallest radii, indoor and
outdoor, radii from 4 x d, speed up to
10 m/s and more
Travel distance
1: freely suspended
2: freely suspended and gliding up to 50 m
3: freely suspended and gliding up to
100 m
4: freely suspended and gliding up to
400 m and more
Resistance to oil
1: No resistance to oil
2: Oil-resistant (following DIN EN
60811-2-1, DIN EN 50363-4-1)
3: Oil-resistant (following DIN EN
60811-2-1, DIN EN 50363-10-2)
4: Oil-resistant (following DIN EN 60811-2-1),
bio-oil-resistant (following VDMA 24568
with Plantocut 8 S-MB tested by DEA)
To make the choice easier for you, we have classified all Chainflex®-cables after
criteria "requirements, oil-resistance and travel distance". The higher the number the better
the cable.
Example: You are looking for a cable which resists highest mechanical
requirements. Aside it should be oil-resistant following VDMA 24568.
The travel distance should be up to 400 m and more for gliding applications.
You choose from the classification overview (see left page):
Requirements: 7
Travel distance: 4
Resistance to oil: 4
This results in the cable's class – here "Class 7.4.4" that you can
take out of each product's page.
In theory the following classes would be possible:
lowest "Class 1.1.1", highest "Class 7.4.4"
