Overview
The Lovejoy ROSTA 17456 SE 45 elastomeric tensioner is a take-up idler for restoring elongated chain or belt tension to original specifications and preventing uneven drive surges and power loss. Self-adjusting and maintenance-free, this tensioner accommodates wear in drive systems without manual adjustment, making it ideal for industrial machinery that runs continuously or intermittently.
Key Features
- Self-Adjusting Design: Automatically compensates for belt or chain stretch without manual intervention
- Elastomeric Inserts: Four elastomeric elements absorb shock and vibration, extending drive component life
- Maintenance-Free Operation: Sintered iron housing with steel arm resists mud, dirt, water, and sunlight
- 360-Degree Mounting Flexibility: Tensioning arm deflects up to 30 degrees either side of neutral position; mounts at any angle
- Dual Force Levels: Two-hole arm design enables two levels of clamping force for application-specific tuning
