FIELD: sealing technology; sealing-up rods and pistons of hydraulic and pneumatic machines.
SUBSTANCE: proposed sealing unit includes bearing part and collar in form of elastic sealing member having circular body and sealing tabs with working edges. Bearing part is made in form of cylindrical bush for linear motion bearing with anti-friction self-lubricating material applied to its sliding surface; bearing part and circular body of collar are connected together forming permanent structure. Device enhances operational reliability and increases service life of sealing unit of cylinder pair (cylinder-piston, cylinder-rod, cylinder-slide block) by excluding bearing function of collar from its working functions and leaving its sealing function only.
EFFECT: enhanced operational reliability; increased service life of sealing unit.
