General information

Gambit Lubawka Sp. z o.o. is a manufacturer of a wide range of sealings and other rubber and rubber/metal products. They are all made of our own rubber mixtures, based on NR, NBR, SBR, EPDM rubbers and their combinations, and third party mixtures FKM and VMQ. Rubber mixtures with standard parameters, as well as with customer defi ned parameters, are modelled according to the agreed shape and basis weight.

Range of applications together with physical and mechanical properties are detailed in the table:

Types of mixtures are defi ned in PN-82/C-94153 or in a customer's specifi cation.With years of experience in manufacturing and application of rubber mixtures and fi nished components we feel competent to select suitable mixture to a customer's specifi ed needs.

We produce a wide range of vulcanized products using presses or injection moulding machines, namely:

• Gaskets for piston rods of shock absorbers for motor industry.

• Gaskets for industrial fi ttings.

• Sealing rings of circular cross-section (O-ring type).

• Gaskets and rubber washers of rectangular cross-section.

• Rubber guiding wheels for hoisting machines.

• Rubber discs for belt conveyors.

• Membranes and diaphragms.

• Sleeves, bumpers, rubber and metal shock absorbers, silent blocks, etc.

• Mud fl aps.

• Other products on the basis of drawings and agreements with customers.

The antistatic and self-extinguishing rubber mixture, designed especially for mining applications, allowed launching the family of products dedicated to customers in that sector. Particularly interesting are rubber guiding wheels for mine cages and other vessels moving in shafts ‒ certifi ed with ‘B’ safety symbol by Polish Institute of Mining Technology (KOMAG), and granted admission for use in underground mining plants by Polish State Mining Authority (WUG).

In addition to standard products we are oriented on new launches. Our own design offi ce and Tool-and-Die Facilities allow us to design and execute the equipment necessary for manufacturing product matching cus-tomer's expectations, in cost-optimized technology with regard to the volume of production. As opposed to many rubber plants focused on large-scale production we are ready to adjust to your needs and expecta-tions.

We also manufacture the following rubber sheets from various rubber mixtures:

Sheets 1000x1000 are available in thickness 5 to 50 mm.Sheets 500x500 are available in thickness 2 to 40 mm.We do not reinforce sheets with fabric spacers.
