The ŘETĚZY VAMBERK company offers a full range of roller chains of all dimensions (pursuant to the DIN, ISO, ČSN, ANSI and GOST standards) and versions (zinc plating version, nickel plating version and stainless steel version). Exact manufacturing on modern equipment, top-quality materials applied and the correct heat treatment guarantee high resistance to wear and dynamic load. We shall gladly meet any customer requirements for design, dimensions, raw material, lubrication, heat and surface treatment of the chains and sprockets. Therefore, you can find a number of roller chains to your specific requirements within our product range - referred to as the roller chains to works standard.

The standard chain pitch ranges from 6 mm (0.236 inch) up to 114.3 mm (4.500 inch)

Self-lubrication roller chains require no lubrication. The special sintered bush is filled with high-quality oil during the production process and the pins are subject to chemical treatment to achieve the minimum wear of the bush. The plates are also subject to additional chemical treatment. The above mentioned adjustments result in reduction of chain extension, guaranteeing its longer service life.

These chains are suitable for all applications where the chain cannot be lubricated for any reason at a later time, for example due to the damage to the final product (oil contamination). Therefore, these products are broadly applied in the paper, electronics and food industry.

The self-lubrication roller chains SLR are fully interchangeable with the standard roller chains.

The difference between the ANSI HEAVY roller chains and the standard ANSI chains consists in the application of thicker plates corresponding to the next larger size of ANSI roller chains. Therefore, the HEAVY chains may guarantee chain resistance to shock loads that is higher by about 10 per cent. At the same time, it is necessary to note that the chain strength is the same as that of the standard ANSI roller chains, therefore the use of these chains is recommended for higher shock loads but for low operating speeds!

Strength of the ANSI SUPER and ANSI SUPER HEAVY chains is approximately 25 to 40 per cent higher than that of the standard ANSI and ANSI HEAVY roller chains. This is achieved both through the narrowed production tolerances of the individual components, through the use of special materials and, in particular, through heat treatment.

Although these chains feature high strength, we also have to emphasize that this criterion is not always a full guarantee of the top product. While strength is important for the maximum chain pulling, it is unfortunately not indicative of the dynamic chain resistance and therefore of its service life.

We wish to emphasize that our design, heat treatment and precision of the individual components as well as the optimized sizes of such chains guarantee a much longer service life of the chains at the required operating loads.

Notice: Only the ANSI SUPER roller chains are interchangeable with the standard ANSI and ANSI HEAVY roller chains!

The standard chain pitch ranges from 25.4 mm (1.00 inch) up to 76.2 mm (3.000 inch)

Self-lubrication roller chains require no lubrication. The special sintered bush is filled with high-quality oil during the production process and the pins are subject to chemical treatment to achieve the minimum wear of the bush. The plates are also subject to additional chemical treatment. The above mentioned adjustments result in reduction of chain extension, guaranteeing its longer service life.

The main difference between the self-lubrication roller chains SL and SLR consists in their strength which is about 30 per cent higher in the SLR chains.

The SL and SLR chains are suitable for all applications where the chain cannot be lubricated for any reason at a later time, for example due to the damage to the final product (oil contamination). Therefore, these products are broadly applied in the paper, electronics and food industry.

The self-lubrication roller chains SL and SLR are fully interchangeable with the standard roller chains.

The standard chain pitch ranges from 12.7 mm (0.500 inch) up to 50.8 mm (2.000 inch)

The self-lubrication roller chains with seals MF can be used when, for any reasons, the chains SL or SLR cannot be used, for example in a very dusty and abrasive environment.

The high-quality lubricant in these chains is closed between the pin and the bush which is additionally protected with the seal to prevent from dirt intrusion.

Notice: operating temperature ranging between -10 °C and +70°C; operating speed from 25 m/min. to 50m/min as the maximum; it is not possible to use the offset link!

The standard chain pitch ranges from 25.4 mm (1.000 inch) up to 76.2 mm (3.000 inch)

• Simple roller chains

The standard chain pitch ranges from 25.4 mm (1000 inch) up to 101.6 mm (4.000 inch)

Thanks to the large tolerance between the inner and outer plates, these chains are highly twisted and flexible. They are ideal for use on curved conveyors or on conveyors with non-coaxial sprockets.

These chains are broadly used in the food industry, packaging industry and textile industry.
