European railcars began using Miner TecsPak® buffer and drawgear springs in 1979. Buffer springs can be used either as a retrofit replacement in existing housings or as the spring in new buffer constructions.
Miner TecsPak® buffer springs comply with EN-15551 and EN-15566 require no maintenance or adjustments after installation.
They resist exposure to dirt and chemicals including lubricants, diesel fuel, gasoline, hydraulic fluids and most solvents that would seriously damage or destroy rubber or urethane, even through temperature fluctuations ranging from –40° C to + 50° C.
The TecsPak buffer springs have been rail-tested throughout Europe on freight wagon and passenger coach applications for nearly 30 years.
