Abstract: A method of making a seal of the type which includes a rigid case, a first seal portion of an elastomeric material and a second seal portion of a low friction material. The method includes placing the rigid case, a wafer of low friction material and two elastomeric blanks into a mold, closing the mold to maintain the aforementioned case, blanks and wafer in position and thereafter further closing the mold to form the seal.

Abstract: A self-aligning clutch release bearing assembly including a tubular bearing carrier and a anti-friction bearing assembly encircling the bearing carrier and supported thereon by means of an annular spring washer which enables relative restricted shifting movement of the axis of the bearing relative to the axis of the bearing carrier to compensate for eccentricity in the axis of rotation of a clutch assembly and a guide member on which the clutch release bearing assembly is mounted. In addition, the spring washer permits restricted angular displacement of the axis of the bearing assembly relative to the axis of the bearing carrier to compensate for angular misalignment between the clutch assembly and axis of reciprocation of the clutch release bearing assembly.
