RUBBER COMPOSITION FOR RUBBER BEARING AND RUBBER BEARING
PROBLEM TO BE SOLVED: To provide a rubber composition for a rubber bearing showing a high modulus and excellent tear resistance after vulcanization, low in viscosity and excellent in scorch resistance, and a rubber bearing using the rubber composition for a rubber bearing.SOLUTION: Provided is a rubber composition for a rubber bearing including diene rubber and carbon black, and in which the diene rubber includes natural rubber and modified isoprene rubber obtainable by being modified by a nitrone compound, in which the content of the modified isoprene rubber in the diene rubber is 15 to 60 mass%.
【課題】加硫後に高いモジュラスおよび優れた耐引裂き性を示し、粘度が低く、耐スコーチ性に優れたゴム支承用ゴム組成物、および、上記ゴム支承用ゴム組成物を用いたゴム支承を提供する。【解決手段】ジエン系ゴムと、カーボンブラックとを含有し、上記ジエン系ゴムが、天然ゴムと、イソプレンゴムをニトロン化合物によって変性することで得られる変性イソプレンゴムとを含み、上記ジエン系ゴム中の上記変性イソプレンゴムの含有量が、１５〜６０質量％である、ゴム支承用ゴム組成物。【選択図】なし
