Logan Drive Cups are manufactured to perform in harsh conditions. Contact surfaces are heat treated to ensure long life. Standard cups are furnished with 1 " and 2 " diameter pilot bores. All models can be furnished with standard lug or gear toothed configurations.

Bolt Circle patterns, bores and axial lengths can be modified to meet specific design requirements.
Drive Cups can be designed and manufactured to be integral with shafts, gears, couplings and stationary members (when used as a brake cup).

Logan Outperforms Electromagnetic Clutches Too!

Logan has the design and manufacturing capability to replace existing and obsolete electromagnetic clutches with Logan technology.

Logan vs. Electromagnetic Clutches

Transmits more torque and has higher RPM capabilities within the same envelope
Eliminates residual DC magnetism in disc packs and bearings - reducing downtime
Logan Disc pack, Bearing Kits, and Seal Kits are available from stock

View of modified standard Logan S300 Series Clutch ( right side of photos) which replaced an Ortlinghaus style electromagnetic clutch (left side of photos). The clutch, drive cup and disc pack were modified on the Logan S300 to fit within the existing Electromagnetic clutch envelope. The Logan transmits more torque within the same envelope. Call Logan for details.

Logan Multiple Disc Clutch and Brake Applications

Logan also manufactures and stocks a wide variety of both friction faced and high carbon-steel discs for wet or dry clutch and brake applications. Logan incorporates the latest technology in friction facing material.

Reduce tooling costs with existing Logan Tooling.
Improve the quality of your existing friction or steel separator discs with improved friction material coefficients, heat treat specifications and mating disc surface finishes.
Reduce costs and improve delivery by ordering small lots from existing Logan disc inventory. Consider Logan when designing or improving upon your single or multiple disc clutch or brake applications.

OEM and Aftermarket designers can take advantage of energy savings and component longevity by utilizing Logan PTOs to drive Auxiliary attachments only when required.
PTO Applications:

Single and Multi-station Pumps
Mobile or Stationary Auxiliary Drives
Connect-Disconnect Direct Drives
Municipal Fire Trucks
Air Rescue Fire Fighting Vehicles
Marine Fishing Boats / Work Boats / Winches

Multi pad pump drive with independent clutch/pump control

New! Logan Bell Housing PTO Clutches

Logan, a leader in SAE PTO Clutches for auxiliary and direct drive applications, Introduces a self-adjusting, heavy-duty Power Take-Off assembly for diesel and Gasoline engines.

The Logan Bell Housing PTO is fluid or air actuated; mounting to a Gasoline or Diesel Engines flywheel.

Logan Clutches - How They Work:
Pressurizing the Cylinder forces the piston to clamp and lock the friction and steel separator discs. When pressure is removed, release springs separate the separator discs and maintain a running clearance between separator and friction discs.

The amount of pressure applied, regulates the amount of torque transmitted through the clutch.

Retrofits with existing Twin Disc® PTOs
Logan PTOs are designed to factory or field retrofit with existing Twin Disc® Mechanical PTOs. The Logan system eliminates mechanical linkages, and utilizes the same Twin Disc® Bell Housing, Shaft, Drive Ring and bearings - making field service center retrofits a straight forward option.

ADVANTAGES:

Field Retrofits with Existing Twin Disc PTOs.
Remote Activation
Self-Adjusting Disc Pack - Minimize Slippage
Eliminates Mechanical Linkages, Hand Levers,Yokes
Air or Fluid Actuated - (Air is ideal for cold start applications
Fast Engagement - Quick Release
Modified Standards Available

Bad complicated mechanical clutch layout

Twin Disc is a registered trademark of Twin Disc Corp. Racine, Wisconsin.
