The silicone rubber composition contains (a) an organopolysiloxane having an alkenyl group, (b) a peroxide cross-linking agent, and (c) a heat stabilizer, wherein (c) includes a compound represented by general formula (1). In formula (1), R1 represents hydrogen or a methyl group, R2, R3, R4, and R5, each independently represent a C1-9 alkyl group, and R6 represents hydrogen or a methyl group.

A bearing (1) is provided, comprising an inner sleeve (6), an outer sleeve (2), and an elastomer body (24), which resiliently interconnects the inner sleeve (6) and the outer sleeve (2), wherein the outer sleeve (2) comprises a circumferential portion (8) and at least one deformation portion (10) that is recessed radially inwards from the circumferential portion (8), and wherein the deformation portion (10) comprises a support-surface portion (12) arranged so as to be offset radially inwards relative to the circumferential portion (8) of the outer sleeve (2), wherein the support-surface portion (12) extends substantially perpendicularly to the radial direction (Ra). A method for producing a bearing is also provided.
