DIR & DILR Type (Drop-In Spacer) Coupling

Direct Replacement for floating shafts in flanged series gear couplings
No need for lubrication or maintenance
Can utilize existing rigid Flanged Gear hubs or custom paper machine hubs
Can be inspected while in operation
Can run at higher speeds than floating shaft gear couplings
Unitized disc pack
Infinite life if properly aligned
Torsionally rigid with minimal back lash
No wearing parts and high resistance to harsh environmental conditions
Shim kits are standard for ease of installation and precise spacer positioning
Anti Flail / Anti Fly piloting option is standard to prevent the spacer assembly from flying out if a disc pack and bolts fail
Adjustable lengths using shaft locking devices

Product Specifics

DIR is provided with F-Style rigid gear coupling hubs
DILR manufactured to work with existing rigid hubs without dist
All spacers are manufactured to the customer’s specified length and a 2.0 service factor

The coupling has two flex planes (one at each disc pack) so it can accommodate parallel misalignment by the angular misalignment in each disc pack. This configuration will also accommodate axial misalignment within the specified limits.

Catalogs

Composite Disc (Cooling Tower) Type Coupling

Lightweight composite material ensures strength & endurance
Stainless steel hubs protect against aggressive environments
Corrosion & ultraviolet light resistant
Theoretical infinite fatigue life

DI Type (Drop-In Spacer) Coupling

"Drop-In” spacer assembly coupling; 2 hubs and spacer assembly (comprising of the spacer, 2 unitized disc packs, and 2 guard rings)
Hubs are piloted - ensures proper centering, as an anti-flail feature
Meets API-610 balance and anti-flail requirements
Oversized hubs available, allows for the use of smaller couplings where applicable

SU Type Industrial Coupling

Single flex plane with two hubs and a single disc pack
For angular and axial misalignment only
Two SU couplings are often combined with a shaft to make a floating shaft coupling; shaft can be hollow for long light weight floating shaft couplings

SX Type Industrial Coupling

Standard disc coupling; 2 hubs, 1 stock length spacer designed to meet industry standard lengths, & 2 unitized disc packs
Two flex planes (one at each disc pack) accommodate parallel, angular, and axial misalignment
Available in 4, 6 and 8 bolt designs; bore sizes up to 13 inches (330mm)
Custom spacer lengths & overload bushing available

SXC Type Close Coupled Industrial Coupling

Close coupled variation of the SX Type coupling
Hubs turned inward and mounted inside the spacer.
Can be used with one or both hubs turned outward for different shaft separations.

SXCS Type Close Coupled Split Spacer Coupling

Split spacer couplings, where disc packs can be serviced or removed without moving hubs
SXCS Type – connecting bolts are installed from the end of the hubs inward, pointing towards the spacer
SXCST Type – connecting bolts are installed from inside the spacer outward, pointing towards the hubs

SXCST Type Close Coupled Split Spacer Coupling

Split spacer couplings, where disc packs can be serviced or removed without moving hubs
SXCS Type – connecting bolts are installed from the end of the hubs inward, pointing towards the spacer
SXCST Type – connecting bolts are installed from inside the spacer outward, pointing towards the hubs
