The purpose of the present invention is to provide an HNBR composition and HNBR crosslinked body having excellent abrasion resistance and pressure resistance, and this purpose can be achieved by means of an HNBR composition characterized by containing 3-20 parts by weight of carbon fibers or wollastonite as a hard filler relative to 100 parts by weight of a hydrogenated nitrile rubber and containing 72-87 parts by weight of a carbon black having an average particle diameter of 40-50 nm, an iodine adsorption amount of 35-49 g/kg, and a DBP absorption amount of 100-160 ml/100 g, as well as by means of an HNBR crosslinked body obtained by crosslinking the HNBR composition. |
