The boot is tubular in shape with cylindrical end fixing zones (4, 5, 6, 7, 8) and a central corrugated bellows section (1). The lateral surfaces of the bellows' corrugations are inclined asymmetrically relative to the boot's lengthwise axis - at an angle of 10 - 30 degrees towards the larger diameter end and an angle of 60 - 80 degrees towards the smaller diameter end. This is designed to shift grease contained in the boot towards the articulated joint as a result of rotation and flexion. The boot is molded e.g. from a supple material resistant to lubricants. |
