The CONTRA Praha, s.r.o. company, headquartered in Prague, specializes in the production and sale of roller, conveyor, energy and motorcycle chains. We offer products from the TSUBAKI, CZ retezy, ZMC and Kabelschlepp companies.
Chain drive is one of the basic structural elements in machine engineering. The market offers chains with increased corrosion resistance and service life, as well as noiseless, Gall and bush chains, maintenance-free chains and quality sprockets.
- Construction of the chain: plate, pivot, bush, cylinder, inner and outter link, connecting elements, connecting and reducing links.
- Basic dimensions: it is neccessary to know three basic dimensions: pitch, cylinder diameter and inner width.
- Construction of the drive: load type, gear ratio, axial distance, correct installation.
- Maintenance requires cleaning and lubrication of chains.
We can offer you the following Tsubaki chains:
drive chains:
- basic roller, maintenance-free Lambda, maraging and anticorrosive chains.
chains with carriers:
- are used for short conveyor operations and in places where noise level must be kept to the minimum.
- accumulation chains are suitable for accumulation conveyors, assembly lines, cooling and drying operations and control lines.
- freewheels are carefully machined by specialized devices to gain high precision.
The CZ chains that we offer are:
- roller chains: the most widely used in almost all fields of drives
- long-link chains: the pitch of the plates is doubled.
- MAHERA: very favorable ratio of performance and quality to price. Produced outside the EU.
- bush chains: structurally based on roller chains, but a rotatable cylinder is not used in them
- special roller chains: with supporting rollers, with a bridge, with lateral bending, with hollow pivots
- flyer chains: carrying chains used to change force direction.
Our other products are:
- conveyor chains that are used for all types of conveyors, conveyor belts and assembly lines.
- tensioning elements to cheaply and efficiently keep the chains properly tensioned
- energy chains
- tools: chain extension gauge, mounting clamps, drifts, riveting tools and anvils.
- plastic chain guides: for extreme dynamic load, complicated chemical conditions and very low temperatures.
