Roller chain 24B-3, pitch 38.1 mm (1 1/2"), C45 steel

Product Description

Roller chain 24B-3 (triplex, pitch 38.1 mm) is a drive component used where durability and dimensional repeatability matter. Manufactured in accordance with DIN 8187 / ISO 606; as a Polish manufacturer, we guarantee full dimensional compatibility with sprockets made to the same standard. Ozdowski chains withstand loads approx. 20% higher than the standard minimum - this is the result of individual hardening of each component (pin, roller, plate) before the chain is assembled.

Technical data

Applications

This chain is used in industrial machine transmissions, hoists and lifts, conveyor drives and agricultural machinery - wherever repeatable performance under load matters.

Frequently asked questions

Which chain has a pitch of 38.1 mm (1 1/2"), a roller of 25.4 mm and an inner width of 25.4 mm?

It is the 24B-3 roller chain according to DIN 8187 / ISO 606, triple-strand (triplex). If the measured chain has these dimensions, the matching product in the Ozdowski range is: roller chain 24B-3, pitch 38.1 mm (1 1/2"), 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 24B these are 38.1 mm, 25.4 mm and 25.4 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.

What is a triplex chain and when is it used?

A triplex chain is a design consisting of three parallel rows of links connected by common pins. It is used where the space for sprockets is limited (a wider sprocket with a larger pitch cannot be used) and the drive must transmit a higher torque than in the simplex version.

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.

How does the hardness of the pin and roller affect the chain's resistance to elongation?

The pin and roller are the components subject to the greatest friction. A precisely machined, hard pin wears more slowly, which limits the build-up of play in the links and the "stretching" of the chain over time.

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.
