Standard types according to DIN 3760, with outer elastomer sleeve, with and without additional dust lip (SL) to protect against light to medium levels of exterior soiling. Available in various designs and materials.
Product Advantages
- Broad range of applications in every sector of industry
- Reliable sealing of the housing bore, even with increased roughness of the bore, thermal expansion and split housings, thus a sealing of low viscosity and gaseous media also possible
- Additional dust lip as additional seal against moderate and medium dust and dirt ingress from outside (BA…SL). (Note: can lead to temperature increase from frictional heat)
Standard types with reinforced outer metal sleeve for easy fitting. With or without dust lip (SL) to protect against exterior soiling.
Product Advantages
- Broad range of applications in every sector of industry
- For larger dimensions and with rough fitting in the locating bore (Note: limited static sealing on the outer casing for low viscosity and gaseous media)
- Additional dust lip as additional seal against moderate to medium dust and dirt ingress (B2…SL) (Note: can lead to temperature increase from frictional heat)
Pressure-resistant type for use without back-up ring in pressurised units such as hydraulic pumps and motors as well as hydrodynamic couplings. With additional dust lip to protect against exterior soiling.
Product Advantages
- Used preferably in pressurised units
- Reliable sealing of the housing bore, even with increased roughness of the bore, thermal expansion and split housings
- Advantages when sealing low viscosity and gaseous media
- Increased thermal stability and chemical resistance
- Additional dust lip as additional seal against moderate to medium dust and dirt ingress from outside
- Small axial dimensions (Note: can lead to temperature increase from frictional heat)
Two-piece Merkel seal set made of PTFE profile ring with one O-ring as a pre-load component.
Product Advantages
Rod seal used in particular in a sealing system.
- Very high resistance to pressure
- Good thermal conductivity
- Very good extrusion resistance
- High resistance to abrasion
- Low friction, free of stick-slip
The V-packing set SDS 01 3/2 is a sealing system with 3 fabric and 2 elastomer sealing rings. This combination guarantees minimal leakage. The V-packings are, due to their geometrical composition, always used used in conjunction with the support ring and pressure ring. V- packing sets are used in extreme application areas.
Merkel polyurethane U-ring with asymmetrical profile, shortened inner lip and second support edge and sealing edge as well as press fit at the outside diameter.
Product Advantages
Single-acting rod seal, also for standardised housings according to ISO 5597.
- Highly wear-resistant
- Good media resistance
- Wide operating temperature range
- Very good static and dynamic tightness
- (Note: low deformation value, therefore not suitable for sealing systems)
Five-piece Merkel compact seal L 43 comprising one profile ring, two back-up rings and two angled bushes.
Product Advantages
The Merkel Piston Seal L 43 is used for sealing pistons with pressure on both sides. The angled rings guide the piston on the cylinder bore.
- No extrusion into the radial sealing gap
- Suitable for rapid pressure change
- Sealing component protected against twisting
Two-piece Merkel seal set for sealing pistons, consisting of one PTFE profile ring and an O-ring as a pre-load component.
Product Advantages
Merkel Omegat OMK-MR is used where a piston has pressure on both sides. OMK-MR is provided with pressure-compensation grooves for rapid pressure change.
- Very high resistance to pressure and hardness
- Good thermal conductivity
- Very good protection against extrusion
- High resistance to abrasion
- Low friction, free of stick-slip
Combination wiper seal without metal reinforcement with special pneumatic sealing edge.
Product Advantages
- Combination seal with minimal space requirements, which seals inwards and wipes outwards
- The component needs no additional element (circlip) for axial fixing within the housing
- Long service life
- Robust design
Compact combination wiper seal without metal reinforcement with special pneumatic sealing edge.
Product Advantages
- Combination seal with minimal space requirements, which seals inwards and wipes outwards
- The special pneumatic sealing edge gives very good tightness with low friction and maintains an effective lubricating film.
- Material with high wear resistance
Merkel complete piston with steel base plate and vulcanised sealing lips with special pneumatic sealing edges.
Product Advantages
- Ready to fit complete piston to which pressure can be applied on both sides with integrated guide
- Easily fastened to the piston rod without additional sealing components
- Long service life
- Constant good sealing behaviour over a wide pressure range (to 1,2 MPa)
- Simple provisioning
Compact Merkel U-ring with asymmetrical profile and special pneumatic sealing edge on the dynamic sealing lip.
Product Advantages
- The asymmetrical profile with the longer and thicker static sealing lip ensures secure seating in the bottom of the groove
- The special pneumatic sealing edge gives very good tightness with low friction and maintains an effective lubricating film.
- Large range
- Minimal axial space requirements
- Integrated pressure relief to prevent an intermediate pressure build-up
Dirt wiper with metal housing; wiper lip protruding.
Product Advantages
Single-acting wiper for the protection of cylinders against ingress of dirt, use in standardised housings, amongst others, according to ISO 6195 Type B.
Dirt wiper without metal reinforcement, protruding wiper lip and base face support.
Product Advantages
Single-acting wiper for the protection of cylinders against ingress of dirt, use in standardised housings according to ISO 6195 Type A.
Using the WSH R to repair the shaft ensures that complete functionality is restored quickly and lastingly. The shaft repair sleeve is used as a counter surface to the rotary shaft seal in the tribological rotation seal system, i.e. in addition to the rotary shaft seal and the lubricant used, the WSH R is the third important component.
O-Rings are endless round sealing rings of circular cross section. They are mainly used to seal stationary machine components – static case – against fluid and gaseous media. In certain conditions, they can also be used as a dynamic sealing component for axial, rotating and oscillating movement.
