igus® plastic bearings for the bicycle industry

40% lower costs, 80% less weight and 100% less maintenance

Change bearing now: plastic instead of metal

What began in 1817 with the Draisian running machine with oiled brass bushes evolved over the years to become a low-weight lifestyle accessory with dry-operating plastic bearings. The "digital bike" and "the bicycle as vehicle" are two important trends in today's bicycle world, where electrification is expanding the range of possible uses of the bicycle in everyday life. This is also changing the requirements placed on the components installed in the bike. Whereas mountain bikes have to cope with impacts and shocks acting on the bearings used in the components when the bike is ridden over rough terrain, the focus in the case of the e-bike is on achievement of the greatest possible range with one battery charge. The bike must therefore be as light as possible although the longer distances travelled lead to greater stress on the individual bicycle components compared to the conventional bike. Save weight, increase service life and minimise maintenance intervals with igus®. Dry operating iglidur® plain bearings made of high-performance plastics are lightweight, extremely wear-resistant and characterised by very low friction values. They defy shocks and bumps and are more resistant than metallic bearings - especially in extreme environmental conditions. Thus dirt, temperature, detergents and humidity are not challenges any more. Due to the elimination of external lubricants and the maintenance often associated with them, the amount of care and repair needed is minimised. Overall three-fold savings: in weight, in maintenance, and also in price.

Advantages of igus® high performance polymers for the bicycle industry:

Self lubricating dry operation

Insensitive to impacts and shocks (no elongation, no displacement)

Very light compared to metallic bearings

Resistant to corrosion and chemicals

Extremely strong and wear-resistant

Vibration-dampening properties

igus® products used successfully in the bicycle industry

Here, you can see some examples of our customers' applications.
Crank Brothers pedals  
Long service life under the most adverse conditions

Crank Brothers, a company in the USA, relies on premium components from igus® for its pedals, among other things. Weight-reducing iglidur® plastic bearings withstand even the most extreme conditions.

SRAM derailleur  
Precision and durability

iglidur® G plastic bearings from igus® used in SRAM derailleurs work extremely precisely and, in contrast to aluminium or metal bushes, are characterised by low weight and high wear resistance.

igus® in suspension forks  
Low-cost, light and low-maintenance

Weight plays a crucial role in bike sport. iglidur® J bearings from igus® are around five times lighter than metal bearings and are ideal for suspension forks. Not only weight but also manufacturing costs were reduced.

Freight bicycle  
Cost-effective and space-saving

For this freight bicycle, robust iglidur® bearings are used in the handlebars, among other things. Apart from the price-reduction and space-saving factors, the plastic solutions from igus® are also lubrication-free and maintenance-free.
