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
Bowex M Tooth Gear Coupling Hub
BoWex® Curved-tooth gear couplings® are flexible shaft connections for a positive torque transmission and used to compensate for axial, radial and angular shaft misalignment. Using curved-tooth gear couplings® avoids any edge pressure in the spline plus angular and radial displacements are avoided so that BoWex® couplings are almost free from wear.
The material combination of steel hubs and polyamide sleeves allows for maintenance free continuous operation with low friction on the teeth. While any metallic materials tend to "corrode" in case of dry running, slide combinations with polyamide and steel are operative without any lubrication or maintenance.
Due to the double cardanic operation of BoWex® couplings, restoring forces can be neglected in case of angular and radial displacements. Periodic fluctuations in angular velocity do not arise.
BoWex® couplings can be assembled both vertically or horizontally with no need for any special assembly tools.
The smooth and hard surface plus the high thermal stability and resistance to lubricants, fuels, hydraulic fluids, dissolvents, and so on, make polyamide an ideal material for components stressed by sliding, particularly for the coupling production.
Note
Hubs are supplied unbored, it is down to the customer to machine to finish, within the couplings parameters.
Each coupling comprises of three parts (sold separately) two coupling hubs and a gear coupling sleeve.
