Ball Bearing Idler Sprockets \u2014 Chain Tension Control<\/h2>\n

Ball bearing idler sprockets are pre-assembled with sealed ball bearings and are designed to be installed on non-adjustable shafts along the chain path to take up slack, maintain proper chain tension, and prevent chain whip on return runs. They rotate freely on a stationary shaft, guided by the chain itself. Available in ANSI #35-#80 and ISO 06B-16B with tooth counts from 13 to 25.<\/p>\n

FAQ<\/h2>\n
\nHow is an idler sprocket different from a drive sprocket?<\/summary>\n
An idler sprocket rotates freely on a stationary shaft. It does not transmit power \u2014 it only maintains chain tension and guides the chain path. A drive\/driven sprocket is keyed to a shaft to transmit torque.<\/div>\n<\/details>\n
\nDo I need to lubricate the bearing?<\/summary>\n
No. The sealed ball bearing is pre-lubricated for life. No maintenance required under normal operating conditions.<\/div>\n<\/details>\n
\nWhat shaft size?<\/summary>\n
The bearing bore determines the shaft size. Standard sizes match common bolt\/shaft diameters. Contact us for specific bore requirements.<\/div>\n<\/details>\n
\nStainless steel idler?<\/summary>\n
