► Finer | Sprockets 20B/24B/28B THRO BORE

Controlled Drive Performance for Heavy Chain Systems

Large pitch chain drives place sustained pressure on every rotating component. Finer 20B, 24B & 28B Thru Bore Sprockets are specified for drive systems where torque loads, chain mass, plus continuous duty demand accurate engagement without compromise.

Seen across bulk handling, quarry operations, agricultural processing, plus fixed plant maintenance, these sprockets suit machinery running beyond light-duty limits. The thru bore configuration supports flexible shaft sizing, making installation simpler during upgrades or retrofits. Many operators specify these sprockets alongside Special Chains to maintain correct pitch matching across heavy transmission layouts.

Within conveyor systems, they are commonly matched with Roller Chains designed for larger pitch operation. Where lifting or transfer motion is involved, these sprockets often operate within assemblies supported by Chain, Wire & Rope components to manage combined load plus movement control.

For guided motion systems, integration with Pulleys, Blocks & Sheaves helps stabilize chain travel under variable load. In high-stress layouts, maintenance teams frequently pair these sprockets with Mounted Bearing Units to control shaft movement plus reduce alignment drift. Larger drive systems may also reference Sprockets across multiple pitch ranges to standardize spare parts.
