Roller chain 12B-2, pitch 19.05 mm (3/4"), with special rubber pad with 2 holes, C45 steel

Product Description

Chain 12B-2 with special rubber top with 2 holes combines the design of a classic 12B-2 (duplex) roller chain with a rubber layer vulcanised onto the plates - this protects the product, reduces line noise and increases grip. The top is fitted with 2 additional mounting holes, enabling the attachment of additional conveyor line elements (e.g. dividers, pushers or holders) - the exact use of the holes depends on the design of the particular line.

The resistance of the cover is provided by NBR rubber (acrylonitrile butadiene rubber) - it offers good resistance to oils, greases, fuels and common organic solvents while retaining high elasticity, as well as operation in a temperature range from -20°C to +100°C. The chain itself is made of steel in accordance with DIN 8187 / ISO 606, which retains the full strength typical of the 12B-2 series.

Technical data

Applications

Applications of the 12B-2 chain with a rubber pad mainly include conveyors on which the transported product must be protected against scratching, shifting or excessive noise. It is used mainly in the food and packaging industries, in logistics and sorting centres, and also in the glass and ceramics industries and in agricultural machinery. The mounting holes in the pad make it easy to adapt the chain to individual conveying solutions that require additional fittings to be attached.

Frequently asked questions

Which chain has a pitch of 19.05 mm (3/4"), a roller of 12.07 mm and an inner width of 11.68 mm?

It is the 12B-2 roller chain according to DIN 8187 / ISO 606, double-strand (duplex). If the measured chain has these dimensions, the matching product in the Ozdowski range is: roller chain 12B-2, pitch 19.05 mm (3/4"), with special rubber pad with 2 holes, C45 steel. The pitch is measured as the distance between the axes of adjacent pins.

What is the 12B-2 chain with rubber cover intended for?

Mainly for conveying goods that could be scratched or shift on a standard chain - the rubber cushions contact and increases grip on the transported product.

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.

Is a version without holes in the pad also available?

Yes, the standard 12B-2 variant with a solid rubber pad (without holes) is also available in our range.

What is the maximum width (L2) and height (h5) for 12B-2?

The pad width (L2) is a maximum of 39.10 mm, and the overall height of the chain with the pad (h5) is a maximum of 16.00 mm.

What is the weight of the 12B-2 chain with a rubber pad?

The 12B-2 chain with a rubber pad weighs 4.0 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.
