Claim:
1. A shock absorber comprising a tubular first portion in the form of a shock absorber casing telescopically receiving a tubular second portion in the form of a piston, said first portion comprising an alignment member which encapsulates a friction element wrapped around said second portion and which is longitudinally movable in between a first stop bearing and a second stop bearing such that friction occurs in between the friction element and the piston during the oscillatory relative movement of said first and second portions, wherein the friction element is entrapped within a closed volume the outer ends of which are defined by the two stop bearings and wherein the friction element has a plurality of tips which extend, parallel to the longitudinal direction of said piston, towards at least one of the two bearings and which hit either of said bearings during the oscillatory back and forth movement of said alignment member during operation, and wherein the inner diameter of the alignment member is larger than the outer diameters of the two stop bearings whereby it is ensured that at least one of the tips of the friction element contacts at least one of the two stop bearings during use of the shock absorber.
