Excellent choice for maintenance-free performance on timing and positive drive applications. Wide range of load capacities and speeds. No lubrication required so you enjoy clean, maintenance-free performance. Energy efficient. Slack side tension is nearly zero and tight side tension is minimal. Reduces overhung bearing loads. Improves motor life. And, there?s less heat build-up. Synchro-Cog is recommended as a replacement for drives where chain and gear can present problems. Ideal where drives are inaccessible making tension maintenance difficult. Or, anywhere that positive synchronization between drive and driven units is a must.</p>
