The bearing assembly includes a bearing housing mounted to the crank shaft housing and including a bore; and a pair of spaced bearings mounted in the bore of the bearing housing and receiving the crank shaft.
One end of the piston is provided with at least one bearing element and a bearing housing.
The rotary target assembly is configured such that when a torque between a bearing housing (403) and a vacuum housing exceeds a predetermined torque, the bearing housing rotates relative to the vacuum housing.
The bearing housing defines a lubricant reservoir (42) in a volume of the bearing housing not occupied by the rolling element bearing (38).
The invention is characterised in that the fixed bearing housing (15) and the moveable bearing housing (16) are connected together by means of a guide rod (17) in each roller.
The bearing receptacle is designed to be locked and unlocked by means of a different drive, said the bearing receptacle comprising a pivotable retaining clip designed for locking the bearing receptacle.
The bearing holder has at least three axial tensioning fingers, between which the bearing holder is received.
A bearing enclosure portion (42) containing bearings (44 and 46) and having a bearing enclosure flange portion (40) is provided.
The bearing assembly provides projections adjacent the bearing seat that engage with an exterior surface of the bearing to restrict the movement of the bearing relative to the bearing seat.
An additional bearing receiving element is arranged upstream from the final bearing receiving element (27) in the direction of the assembly of fibres.
