RoHS (“Restriction of Hazardous Substances”) is an EU directive that limits specific hazardous materials in electrical and electronic products to protect human health and the environment.
RoHS-compliant plain bearings either exclude or contain only permissible levels of substances such as lead, mercury, cadmium, hexavalent chromium, and certain brominated flame retardants.
Most modern plain bearings, especially those used in electrical or electronic equipment, meet RoHS standards, but it is advisable to confirm with the manufacturer or supplier.
All self-lubricating bearing materials with this mark comply with RoHS directive requirements.
**RoHS (2011/65/EU)**
On June 4, 2015, the European Union issued Directive (EU) 2015/863, amending Annex II of RoHS 2.0 (2011/65/EU). This update introduced four phthalate esters—DEHP, BBP, DBP, and DIBP—with a maximum concentration of 0.1% in homogeneous materials. Appendix II now lists ten restricted substances, including four heavy metals, two brominated flame retardants, and four o-benzene plasticizers.
**ELV (2000/53/EC)**
The ELV Directive (2000/53/EC) mandates the recycling of end-of-life vehicles to protect the environment and reduce waste. It prohibits lead, cadmium, mercury, and hexavalent chromium in cars manufactured after July 2003, setting maximum limits as follows:
– Cadmium (Cd): ≤100 ppm (0.01%)
– Mercury (Hg): ≤1000 ppm (0.1%)
– Lead (Pb): ≤100 ppm (0.1%)
– Hexavalent Chromium (CrVI): ≤1000 ppm (0.1%)
RoHS, meaning “Restriction of Hazardous Substances,” regulates unwanted components in electrical and electronic equipment within the EU. Due to technical limitations, specific thresholds are set for substances commonly used in electronics, such as lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE. Examples include lead in solder and metallic bearings, and PBB as a flame retardant. These substances are also frequently found in metallic alloys.
Self-lubricating bearings positively impact environmental protection in several ways. They reduce lubricant consumption by eliminating the need for external lubrication, resulting in fewer chemicals released into the environment. Maintenance and waste are decreased as regular upkeep and lubricant changes are no longer necessary, minimizing waste products like used oils and greases. These bearings often have a longer service life, leading to fewer replacements and reduced waste over time. Additionally, their lower friction levels contribute to energy savings across various applications.
Incorporating self-lubricating bearings supports sustainable industrial practices by reducing material use and energy consumption through lightweight designs. They enable oil-free lubrication, further decreasing environmental pollution. Their smooth, low-friction surfaces lower equipment energy consumption and extend maintenance cycles, reducing costs and pollution. Composites of metal and non-metal materials enhance mechanical strength and wear resistance, prolonging equipment lifespan. These bearings can withstand harsh conditions such as dust, vacuum, extreme temperatures, and radiation, simplifying equipment design and manufacturing. They comply with environmental standards like RoHS and REACH, and their simplified processing techniques reduce energy consumption and manufacturing costs compared to traditional bearings.
