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".

Product Details
Ruland Oldham Style Couplings
Paradrive™ couplings are ideal for motion control applications, especially those utilising stepper or servo motors. Their low inertia design is ideally suited to higher speed applications and where electrical isolation is also required. Small angular and axial misalignments may be accommodated.
Torque Discs
Nylon discs (resilient) - help dampen vibration and noise,Acetal discs (backlash-free) - designed for precise applications requiring zero backlash and higher torque capacity
Note
Size 13 discs not suitable for use with clamp style couplings
Securing: 13mm and 19mm anodised aluminium hubs are secured to the shafts with one set screw on each end. 33mm, 35mm and 41mm hubs have 2 set screws set 90° apart
