O-rings - Import export

Orings are universal sealing elements used to seal against liquid or gaseous median. They are suitable for static and minor dynamic applications. Orings can be used for radial and axial sealing. The sealing occurs during installation by the radial or axial compression of the crosssection. During operation, the median pressure increases the deformation of the Oring and so increases the sealing effectiveness. For best sealing effectiveness, the Oring should have the largest possible crosssection. During installation the correct groove size, compaction, elongation/compression should be ensured. By static use the compaction should be 15 30% of the crosssection. By dynamic use it should be 10 18% (hydraulic), 4 12% (pneumatic). With regard to the ID, when installed the Oring should be stretched max 6% compressed max 3%

Self-aligning pads are used to support and clamp unmachined and machined workpieces. They also serve as stops, supports and thrust pads in fixtures and toolmaking. Ball secured against rotation. Form O: The abrasive diamond surface is bonded firmly to the ball. It is ideally suited to supporting smooth or slippery applications with a minimum of clamping pressure. This allows the diamond particles to get a firm grip on a very small area with minimum damage to the surface. The diamond surface offers excellent wear resistance. Form P: The polyurethane surface is vulcanised firmly to the ball. It is abrasion-resistant and does not discolour. It offers optimum protection against damage to delicate surfaces. The pearl-like surface gives a firm grip and allows air to escape so as to prevent any suction effect between the contact surface and the self-aligning pads. Advantages: The built-in O-ring holds the ball in place and keeps dirt and foreign particles out, ensuring uniform movement.

Body tempered, black oxidised. Ball hardened, bright. Inserts: Form C, F hardened, black oxidised. Form M with carbide serrations, black oxidised. Form K white. Form E hardened, bright. Form O diamond impregnated surface comparable to 100 grade abrasive grit. Form P polyurethane surface, hardness 60 Shore. Note: Self-aligning pads are used to support and clamp unmachined and machined workpieces. In addition, they serve as stops, supports and thrust pads in fixtures and toolmaking. The ball can be removed from the housing by applying light pressure to the socket head screw. Ball secured against rotation. Advantages: Highly cost-effective as inserts can be exchanged. The built-in O-ring holds the ball in place and keeps dirt and foreign particles out, ensuring uniform movement. Drawing reference: Form C: flattened steel insert, smooth Form E: flattened stainless steel insert, smooth Form F: gripper face Form K: flattened POM insert, smooth
