Tb Wood'S 7E EPDM Coupling Insert
EPDM sleeve coupling insert for size 7 applications handles up to 5,250 RPM and 940 in-lb torque
- Handles up to 940 in-lb torque for reliable power transfer
- Operates at speeds up to 5,250 RPM in demanding drives
- EPDM rubber withstands 275 Degrees F for extended service life
- 2-piece design with retaining ring simplifies installation and maintenance
- Accommodates 1 Degree angular and .02 in parallel misalignment
Application Scope
This EPDM sleeve coupling insert fits Coupling Size 7 and suits blowers, compressors, conveyors, mixers, motors and pumps. It transmits up to 940 in-lb of torque at speeds up to 5,250 RPM. Buyers needing higher torque capacity or larger coupling sizes must select a different insert.
Misalignment & Speed Limits
The insert tolerates 1 Degree of angular misalignment and 0.02 in of parallel offset. Maximum operating speed is 5,250 RPM, with a rated 1.5 hp at 100 RPM. Torsional stiffness is 2,769 in-lb/rad. Applications exceeding these limits will require an alternative coupling solution.
Build & Daily Implications
The two-piece design with a retaining ring allows installation and replacement without moving the connected shafts. EPDM rubber withstands temperatures up to 275 Degrees F and resists ozone and weathering. The insert measures 4 11/32 in outside diameter by 2 3/16 in width. Environments above the temperature limit or requiring chemical resistance beyond EPDM properties are not suitable.

Questions about this item
Should I select the 7E EPDM insert for my size-7 coupling or is there another version for the same hub?
The 7E EPDM insert is made for Coupling Size 7 hubs. It fits the 4 11/32 in outside diameter and 2 3/16 in width specified for this size.
What does the 940 in-lb torque rating mean once the insert is installed?
940 in-lb is the peak torque the insert can transmit. At 100 RPM the corresponding power limit is 1.5 hp; do not exceed 5,250 RPM.
How much misalignment can the EPDM sleeve handle in practice?
The insert allows 1 degree angular and 0.02 in parallel misalignment while transmitting torque through the 2-piece sleeve with retaining ring.
