Sealing strips and end deckles made of rubber graphite
In 1994, Röchling Industrial expanded its product range to include rubber graphite strips to keep apace of the increasing demands within suction roll technology. With the constant enhancement in our in-house suction roll test bench, we have developed the world's best sealing strip material.
Supplying a full sealing strip package
Röchling Industrial is the only supplier to offer all the components and materials suitable for use as suction roll seals. The sealing strip alone does not provide a functional sealing unit for suction rolls. Only the right loading tube and sealing strip holder with a sufficient amount of flexibility and chemical resistance ensure the level of protection required.
As we supply a complete unit, our customers find the ordering and stock processes much easier and are assured of flawless sealing units. The flexible modular system also ensures rapid turnaround times. Why not experience the unrivaled quality of this solution for yourself? Take a look at our ROBASEAL sealing strips and end deckles made of rubber-graphite.
ROBASEAL-S
Premium rubber graphite-based material for heavy-duty sealing strips. ROBASEAL-S together with highly temperature-resistant silicone oil considerably reduces the amount of water lubrication required while significantly increasing service life and ensuring functionality for the entire usage period.
- Increased service life (less friction, less wear)
- Reduced amount of water lubrication
- Longer service cycles
- Lower energy consumption
Application
All suction rolls. Saving energy and water lubrication and increasing service intervals.
Doubled service life
ROBASEAL-S can increase the service life by up to 100% compared with ROBASEAL-A while maintaining the same operating parameters (spray water volume, loading pressure, vacuum).
Reduction in water lubrication
Suction rolls require approx. 10 m³ water lubrication for each meter in width over 24 hours in order to lubricate the sealing strips. The unique silicone admixture in ROBASEAL-S enables the water lubrication volume to be reduced by 30% – with no impact on service life.
1/3 reduction in water lubrication means a 30% reduction in the risk of remoistening with no impact on endurance and also lowers production costs!
ROBASEAL-A
Sealing strips made from rubber graphite with outstanding mechanical characteristics and emergency running properties for increased endurance.
- Increased service life (low wear, temperature resistance)
- Low coefficient of friction = low energy consumption
- Excellent emergency running properties
Application
All suction rolls with a speed of up to 2,000 mpm.
ROBASEAL-L
This material blend is the perfect compromise between a pure rubber graphite and a thermoplastic strip. It has precisely the same characteristics as a graphite strip at production speeds of up to 800 m/min. Despite the thermoplastic element of the material blend, it demonstrates good emergency running properties.
- Breakproof and flexible sealing strip
- Outstanding emergency running properties thanks to the incorporated graphite
- Energy-saving – low coefficient of friction compared with thermoplasts
Application
All suction rolls with a speed of up to 800 mpm. Strips and end caps available.
ROBASEAL SeaLencer
A unique patented solution combining friction energy and effective noise reduction for suction rolls. ROBASEAL-S/-A/-L can be used as the basic material.
- Sound pressure halved
- Less wear
- Minimum running in
- Lower energy consumption (friction surface reduced by 90%!)
Special feature
Reduced friction surface: An effective solution for reducing friction energy as well as noise and sound for suction rolls.
| Conventional sealing strip | ROBASEAL SeaLencer |
| Wide friction surface | Reduced friction surface |
| • Significant wear | • Reduced friction resistance |
| • Higher energy consumption | • Shorter running-in times |
| • Less endurance | • Lower energy consumption |
| • Greater pull | • Less wear |
Application
In the suction roll on any type of paper machine
ROBASEAL Energy Saver Light
This product line is the link between ROBASEAL-S and the SeaLencer. This version only reduces the sound level slightly but uses the reduced surface area to save drive energy and can be used in the position reserved for the wide sealing strip without any modification, which is a bonus for many customers.
- Noise-reducing
- Friction surface reduced by 80%
- Lower energy consumption
- No modification required
Application
In the suction roll on any type of paper machine
ROBASEAL end deckles
Suitable for all ROBASEAL sealing strips.
Arrange technical advice
The performance and reliability of components used for paper machines are influenced by a variety of factors. These criteria need to be considered in order to make the right choice. Examples:
- Mechanical loading
- Thermal loading
- Operating temperature
- Design requirements
- Dimensions and tolerances
