Salah satu bagian dalam part shock absorber adalah oil seal shock absorber. Fungsi dari oil seal tersebut adalah untuk meredam kejutan atau getaran akibat kondisi jalan yang tidak rata untuk memberikan kenyamanan bagi pengendara. Kondisi saat ini oil seal shock absorber yang diproduksi mudah aus dan rusak. Beberapa keluhan konsumen tentang oil seal shock absorber adalah mudah mengeras, mudah aus, mudah sobek, tidak tahan oli dan suhu tinggi. Tujuan dari penelitian ini adalah mendapatkan formulasi oil seals shock absorber tahan oli dan tahan panas serta mempelajari teknologi proses pembuatan oil seal shock absorber. Bahan baku yang digunakan untuk membuat oil seal shock absorber adalah Nitrile Butadiene Rubber (NBR) dan campuran NR/NBR sebagai bahan pengisi digunakan 2 (dua) jenis carbon black (CB) berdasarkan ukuran partikel yaitu N 330 dan N774. Proses pembuatan komposit menggunakan alat two roll mill dan proses pencetakan produk dengan mesin hydraulic press pada suhu 150ºC dan tekanan 150 kg/cm2. Pengujian komposit dilakukan berdasarkan sifat mekanik dan kimia. Hasil penelitian menunjukkan bahwa oil seals shock absorber yang dibuat dari komposit NBR dengan bahan pengisi campuran N330/N774 mempunyai sifat mekanik unggul dan sifat ketahanan oli lebih baik dari produk oil seals shock absorber yang diperoleh dari pasaran. Sifat mekanik vulkanisat oil seals shock sabsorber dari campuran NR/NBR mengalami penurunan bila dibandingkan vulkanisat dari bahan NBR. </div> <!--[if gte mso 9]><xml> <w:WordDocument>
