Roller chain 20B-1, pitch 31.75 mm (1 1/4"), with rubber pad, C45 steel

Product Description

Chain 20B-1 with rubber pad is a simplex roller chain of pitch 20B-1 with a vulcanised rubber pad, used on conveyors where the transported product must not come into contact with metal.

The NBR rubber (nitrile butadiene rubber) used for the top provides good resistance to oils, greases, fuels and common organic solvents while maintaining high elasticity, and the operating temperature range is from -20°C to +100°C. The steel construction of the 20B-1 chain complies with DIN 8187 / ISO 606.

Technical data

Applications

The 20B-1 chain with rubber cover is used on conveyors carrying products that need protection against scratching, damage or slipping, and the cover additionally reduces line noise. It is most often used in the food, packaging and logistics industries, but it performs equally well in sorting centres, the glass and ceramics industries and in agricultural machinery.

Frequently asked questions

Which chain has a pitch of 31.75 mm (1 1/4"), a roller of 19.05 mm and an inner width of 19.56 mm?

It is the 20B-1 roller chain according to DIN 8187 / ISO 606, single-strand. If the measured chain has these dimensions, the matching product in the Ozdowski range is: roller chain 20B-1, pitch 31.75 mm (1 1/4"), with rubber pad, C45 steel. The pitch is measured as the distance between the axes of adjacent pins.

When is it worth choosing a 20B-1 chain with a rubber pad?

For applications where a standard metal chain could damage or scratch the conveyed product - the rubber cover eliminates direct metal contact with the goods.

What material is the pad made of?

As standard, NBR rubber (acrylonitrile-butadiene rubber), with a hardness of 75 ±5 ShA (standard). This material provides good resistance to oils, greases, fuels and common organic solvents while maintaining high elasticity.

Does a chain with a rubber top require lubrication?

The chain mechanism itself (pins, bushes, rollers) requires periodic lubrication, as with any roller chain - the rubber top does not require lubrication.

What is the maximum width (L2) and height (h5) for 20B-1?

The pad width (L2) is a maximum of 35.40 mm, and the overall height of the chain with the pad (h5) is a maximum of 27.00 mm.

What is the weight of the 20B-1 chain with a rubber pad?

The 20B-1 chain with a rubber pad weighs 6.2 kg per running metre.

What does the lead time depend on?

When ordering, please check the current stock level of this chain - the lead time depends on it and is clearly stated according to the quantity available in each warehouse. The stock level is shown above the product price and may vary depending on the warehouse.
