New Technology for Quieter Blocks in the Future

The problem with cast iron blocks is not so much the squealing when braking, but more the rumble of the rolling noise, caused by metal wear debris particles becoming welded onto the wheel.

The K-block material, produced using plastic composite technology, leaves no material deposits on the running surface of the wheel, thus preventing a rumbling noise.

The noise levels of wheels braked using K-blocks are reduced by up to 8 dB(A), slashing perceived rolling noise by half.

Firmly in the Green on Ecology and Economy

The JURID 816M K-block with reduced noise emissions is a significant contribution by Federal-Mogul Motorparts towards protecting the environment.

Additionally, it also offers several economic benefits. K-blocks from Jurid not only minimize wheel wear, they also reduce wear on the brake block by up to 80 % compared with GG-blocks. From the user’s perspective, JURID 816M K-block last up to five times longer and therefore increase maintenance intervals by a factor of four.

In anticipation of the impending legal requirements, the first freight train operators have already launched innovation programs to convert their freight cars from cast iron blocks to K-blocks. Careful scheduling of maintenance intervals makes the conversion process very cost effective. Operators who have already made the switch are experiencing a significant competitive advantage.

The JURID 816M K-Block as an Alternative

Not only can the JURID 816M K-block can not only be fitted as original equipment or when converting existing freight cars with cast iron brakes, it can also be used in place of other composite block products. After all, the JURID 816M K-block is approved for all major standard applications. Federal-Mogul Motorparts engineers will be happy to assist you on any applications not covered by these standards.

JURID 816M as Original Equipment

Since UIC approval was granted, and with EU emissions regulations imminent, K-blocks are being fitted to new freight cars as original equipment.

In light of glowing references and convincing life cycle cost arguments, more and more JURID 816M K-blocks are finding their way into the brake systems of leading freight car manufacturers.

Old GG Blocks in the Line of Fire of new EU Directives

Reducing CO2 emissions is of paramount importance to European Union authorities, as is encouraging a shift from road to rail for the transport of freight. However, more rail traffic also leads to a considerable increase in noise emissions along rail routes. A Catch-22 situation? No, thanks to a new friction material technology!

Federal-Mogul Motorparts Friction Materials: A BMWi Partner in the LäGiV* Research Project

Against a backdrop of impending legal regulations on noise reduction for freight trains, and in agreement with the German Federal Ministry of Transport, Building and Urban Development (BMVBS), the German Federal Ministry of Economics and Technology (BMWi) initiated the LäGiV* project to study and develop suitable measures. Federal-Mogul Motorparts is a major contributor to this project, and is even able to offer an immediate product solution – the JURID 816M K-Block.
