Rotary seals
Industrial radial seals
Industrial radial profiles, including fabric-reinforced designs and seals with clamping or multiple sealing elements. Housing geometry and retention must match the selected design.
View profiles and technical sheets · 12Rotary seals
Cassette and combination seals
Units combining sealing with additional protection elements. Designs differ in lip arrangement, running surface and installation method.
View profiles and technical sheets · 8Rotary seals
Axial seals and V-rings
Lip rings running against an axial counterface. Match the profile to the shaft diameter, available space and counterface position.
View profiles and technical sheets · 5Rotary seals
Shaft repair sleeves
Thin sleeves for restoring the running surface of a radial seal. Check shaft size and condition, lip contact position and installation procedure.
View profiles and technical sheets · 1Rotary seals
Sealing end caps
Closure elements for housing bores. Select the design according to bore diameter, installation depth, coating and reinforcement.
View profiles and technical sheets · 3Hydraulics
Hydraulic rod seals
Profiles sealing the rod of a cylinder or actuator. Distinguish single- and double-acting designs, energising systems and extrusion support elements.
View profiles and technical sheets · 42Hydraulics
Hydraulic piston seals
Seals separating cylinder chambers at the piston diameter. Match the design to pressure direction, groove geometry and any support rings.
View profiles and technical sheets · 41Hydraulics
Symmetrical seals
Profiles with symmetrical lip geometry. Suitability for rod or piston sealing must be confirmed for the individual design and installation conditions.
View profiles and technical sheets · 8Hydraulics
Wipers
Elements removing contamination from the rod surface during retraction. Profiles differ in lip geometry, housing fit and reinforcement.
View profiles and technical sheets · 18Hydraulics
Double wipers
Profiles combining a wiping lip with an additional functional edge. Fluid film control and intermediate pressure must be checked with the rod seal arrangement.
View profiles and technical sheets · 12Hydraulics
Rod guide rings
Rod guiding elements supporting transverse loads. They do not replace a seal: check material, bearing length and installation clearance.
View profiles and technical sheets · 5Hydraulics
Piston guide rings
Rings guiding the piston within the cylinder bore. Select material and bearing area according to loads and sliding conditions.
View profiles and technical sheets · 6Hydraulics
Guide bands
Guiding strips supplied, depending on design, cut to size or as band material. Define thickness, width, cut length and end gap for the groove.
View profiles and technical sheets · 4Hydraulics
V-packing sets
Sets of V-shaped sealing elements with support or pressure rings. The number, orientation and preload of the elements form part of the assembly specification.
View profiles and technical sheets · 12Hydraulics
Swivel seals
Profiles separating circuits in swivelling or oscillating joints. Assess pressure, relative speed, medium and groove geometry together.
View profiles and technical sheets · 6Pneumatics
Pneumatic rod seals
Rod seals for pneumatic cylinders, including designs with an integrated wiping function. Assess the profile against lubrication, friction and motion conditions.
View profiles and technical sheets · 9Pneumatics
Pneumatic piston seals
Seals and compact assemblies for pneumatic pistons. Designs may integrate guidance, cushioning or sensing elements: check the actual configuration.
View profiles and technical sheets · 15Pneumatics
Cushioning seals
Elements used in pneumatic end-of-stroke cushioning systems. Geometry, flow passages and valve behaviour depend on the selected design.
View profiles and technical sheets · 3Static seals
O-rings
Circular-section sealing rings identified by inside diameter and cross-section diameter. Select compound, hardness and groove design for the application.
View profiles and technical sheets · 7Static seals
X-rings
Four-lobed rings for static or dynamic applications compatible with the profile. Check groove dimensions and installed preload.
View profiles and technical sheets · 1Static seals
Sealing cords and strips
Cord and strip sealing materials for application-specific arrangements. Specify the section and any joint: a joined ring is not automatically equivalent to a moulded ring.
View profiles and technical sheets · 3Static seals
Back-up rings
Support rings limiting seal extrusion into the clearance gap. Check the section, pressure direction and whether support is needed on one or both sides.
View profiles and technical sheets · 5Static seals
Flange and cover seals
Profiles for static sealing between flanges, covers and mating surfaces. Groove shape, compression and the clamping arrangement form part of the selection.
View profiles and technical sheets · 5Static seals
Metal-elastomer bonded seals
Washers combining a metal support with an elastomer element for sealing screwed connections. Lip position and centring vary between designs.
View profiles and technical sheets · 6Static seals
Clamp connection seals
Gaskets for clamp connections with specific profiles and dimensional series. Nominal size alone does not always identify the connection geometry.
View profiles and technical sheets · 1Special components
Diaphragm accumulators
Components separating gas and fluid by a diaphragm. Volume, pressure, precharge and assembly requirements must be specified for the complete component.
View profiles and technical sheets · 1Special components
Bellows
Flexible protection and connection elements with defined attachment areas. Specify working length, stroke, connection diameters and expected movements.
View profiles and technical sheets · 3Special components
Diaphragms and coated fabrics
Flexible diaphragms and reinforced materials for fluid separation or motion transmission. Drawing, retention and duty cycle guide the selection.
View profiles and technical sheets · 2Packings
Stuffing box packings
Braided stuffing box packings differing in yarn, impregnation and application. Define the section, number of rings and gland adjustment alongside service conditions.
