Legislation and Compliance
RoHS Certificate of Compliance
EU Directives 2011/65/EU and 2015/863 restrict the use of the 10 substances below in the manufacture of specified types of electrical equipment.
Whilst this restriction does not legally apply to components, it is recognised that component “compliance” is relevant to many customers.
RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
| Substance | Concentration |
| Lead | 0.1% |
| Mercury | 0.1% |
| PBB (Polybrominated Biphenyls) | 0.1% |
| PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
| Hexavalent Chromium | 0.1% |
| Cadmium | 0.01% |
| DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
| BBP (Benzyl butyl phthalate) | 0.1% |
| DBP (Dibutyl phthalate) | 0.1% |
| DIBP (Diisobutyl phthalate) | 0.1% |
The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".
RS Components has taken all reasonable steps to confirm this statement. Information relates only to products sold on or after the date of this certificate.

Product Details
Aluminium Flexible Shaft Couplings
Designed to perform where higher speeds, greater misalignment, and limited lubrication would exceed the capabilities of other couplings. Each coupling is manufactured as one piece, thereby eliminating mechanical joints and possible failure points.Two fixing styles available:,Typical applications include encoders, stepper motors, robotics, measuring instruments, servo systems, pumps, valves, fans etc., (i) Set Screw style is secured using one grub-screw per shaft (staggered at 120°) , (ii) Clamp style fixing uses one socket head cap screw per shaft.
Note
The coupling illustrated shows the Clamp style fixing.
Constant velocity couplings with high torque capacity and zero backlash
Torsionally rigid one-piece construction
Not temperature sensitive
High or low speed operation and reversible
No lubrication required
Up to 3° of axial misalignment allowable
