Oz Seals manufactures large seals for applications that would require superior materials and unique seal profiles. We have a vast experience and knowledge of precision machining for large custom seals. Never compromising on quality, we have been manufacturing a huge number of large custom seals with no limit in diameter. At Oz Seals, we are dedicated to manufacturing large seals for the challenging and critical industries. With our fast, precise and advanced Oz Machines, Oz Seals is able to formulate any special seal profile with large seal dimensions according to your drawings provided in no time at all.    

Special seal form­­


 

Precision manufacturing for large seals

Step 1: CASTING

The material is determined by the application. If seal is subjected to routine failures,  a better grade material can be considered. Oz seals has formulated a range of Super Polymers – superior materials with excellent temperature characteristics that have proven itself in tough application situations.

 

Step 2: PROGRAMMING

Oz Seals CAD/CAM software processes seals automatically within minutes. Select from over 250 profiles covering all seal types and adjust the required parameters on a graphical interface.  Seals are automatically generated through the CNC machine to be cut in an instant.

Step 3: MANUFACTURING

Once  a CNC program sheet is processed, the manufacturing of the large seal can begin. At any point, engineers can change the specified dimensions and customize a standard profile to suit the needs of our customers. All necessary operations, tools, cutting feeds and speeds can be modified if required.

 

Step 4: PACKAGING

Due to its elasticity and flexibility of Oz Super Polymers,  Oz large seals are easily packed and shipped to our customers.

Step 5: DELIVERY

At Oz Seals, we understand the importance of seals and the immense costs a breakdown can cause to a business – that is why our emphasis is placed on sealing solutions with a very quick turnaround. One hour service is provided if necessary.


 

Industries using Oz Large Seals

 

HYDRAULIC CYCLINDERS

 

Oz Seals offer the complete design of hydraulic cylinders for harsh applications: heavy industry, offshore, presses, etc.

Oz V-packings: “multi-lip” seal concept on piston and piston rod to avoid sudden seal collapse in critical cylinders; best solution for old presses.

Oz wipers: keeping contaminants away from seal area for best seal efficiency.

Oz line: PTFE composite seals and wipers for low friction requirements, for example HAGC cylinders in steel mills.

Oz line: machined seals in different polymers, for example polyurethane U-cup seals.

T100PTFE: guide rings to prevent metal contact and to provide smooth and aligned movement of the cylinder.

HYDRAULIC PRESS

 

Oz Seals offers the seal design of main cylinder and side cylinders of hydraulic presses:

– metal forging
– metal extrusion
– scrap metal processing
– metal forming
– wood panels
– ceramic

From the very difficult working conditions of presses for open dye forging to the low friction requirements of ceramic presses, Oz Seals can provide the most suitable and long-lasting seal.
Oz V-packings with diameter in excess of 1,5 meter are produced in less than 1 week for the maintenance of giant presses.

HYDRO POWER

 

In the long run the seal variety has grown a lot and today the hydropower seal package comprises different profiles and materials for:

– Kaplan, Francis and Pelton turbines;
– Spherical and butterfly valves;
– Servomotors;
– Gate wheel bearings;
– Gate hydraulic cylinders.

Oz Seal’s technical department can also recommend the correct guiding made from water lubricated materials.

The “ISP” and “VSP” technologies enable the gluing and hot joining of split seals on site, to avoid costly dismantling of parts of hydropower machineries.

METALLURGY

 

In a steel mill there is a large number of seals, whose failure can cause costly consequences.
Large expertise and best seal quality are essential to withstand the extreme working conditions of this environment and to avoid unplanned machinery shutdown.

Oz Seals offer a large package of dynamic seals for:
– continuous casting
– Hot and cold rolling mills for any metal shape
– Gearboxes
– Heavy duty hydraulic cylinders
– Other kind of heavy machinery

From new design to maintenance, Oz Seals’s technical department is ready to improve the seal performance.

SHIP BUILDING

 

Oz Seals also specializes in seal solutions for ships, taking the huge responsibility of:

– avoiding pollution into seas or lakes due to lubricant leakage;
– keeping seawater outside the ship propulsion, steering and stabilizing components.

The seals must cover the scheduled working period as unexpected maintenance intervention due to heavy seal leakage leads to extremely high costs and sometimes to the drydocking.

Ship components:

– Thrusters
– Fin stabilizers
– Rudders and steering gears
– Propeller shafts, bearings and gearboxes
– Winches

Our seals are fitted in new ship components; to avoid costly disassembling of rotary shafts. Our seals are also available in split version.

Oz Seals’s laboratory has tested the chemical compatibility of rubber compounds with a variety of “Environmental Acceptable Lubricants” (EAL) to satisfy the “Vessel General Permit” (VGP) regulations.

WIND POWER

 

Wind power market has become strategical for Oz Seals since giant wind mills require large diameter seals and offshore wind mills need even more reliable and long-lasting seals to avoid lubricant leakage and the risk of damage to bearings and gearboxes.

Oz Seals manufactures Oz rotary shaft seals of various diameters. Our shaft seals are wear resistant, low temperature and has excellent ozone weathering.

CUSTOM

 

We devote our best energies to the sealing solutions of the future.

Our vast technical knowledge combined with our experience “in the field” has enabled us to design new seals for machine manufacturers and also increase the life span of our seals for the end users.
