Roller chain 28B-1, pitch 44.45 mm (1 3/4"), C45 steel

Product Description

Chain 28B-1 (simplex) is a proven solution for power transmission in mechanical systems, made with a pitch of 44.45 mm. The chain is manufactured in accordance with the standard DIN 8187 / ISO 606; each pin, roller and plate is individually hardened, which we as a European manufacturer consider key to durability. Thanks to hardening each component separately, even before the whole chain is assembled, Ozdowski products achieve a breaking strength about 20% higher than the minimum values specified by the standard.

Technical data

Applications

Typical applications include drives in the food industry (packaging lines, sorting machines), the packaging and automotive industries, as well as agricultural and construction machinery, where the chain works together with sprockets of the same pitch.

Frequently asked questions

Which chain has a pitch of 44.45 mm (1 3/4"), a roller of 27.94 mm and an inner width of 30.99 mm?

It is the 28B-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 28B-1, pitch 44.45 mm (1 3/4"), C45 steel. The pitch is measured as the distance between the axes of adjacent pins.

How do I choose the right roller chain for an industrial drive?

The key is to determine three parameters: pitch, inner width and roller diameter - for 28B these are 44.45 mm, 30.99 mm and 27.94 mm respectively. In addition, operating conditions should be taken into account: load, rotational speed and environment (dust, moisture), in order to select the right version.

How can industrial chains be cleaned of dirt and mud without damaging the links?

Avoid aggressive acid cleaners and pressure washers at close range, as water can be forced under the rollers. Dedicated cleaning agents and soft brushes are a better solution.

Why is it not advisable to break a chain with a hammer and punch?

Hammer blows generate uncontrolled forces that can damage the fit of the pin in the plate of the adjacent link, and a ricocheting punch can be dangerous and may damage the roller surface.

How does lateral runout of the sprockets affect roller chain durability?

Misalignment of the sprockets causes the chain to jerk alternately from side to side. The inner surfaces of the plates then wear, and the pins are subjected to damaging bending forces.

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.
