Friction Clutches, Adjustable & Fixed Torque

Clutches are typically made from steel and are paired with another material that generates friction. This material can be fiberglass, Kevlar, brass, steel, engineer polymer, ceramics, or a metallic compound. A clutch connects the two shafts of a device, so they can spin in unison or spin at different speeds, depending on the situational needs.


Fixed and Adjustable Torque Friction Clutches for Synchronous Motion Applications

At Ondrives.US, we offer a variety of friction clutches for all your application needs. Our adjustable and fixed torque friction clutches can function as safety override devices that instantly changes from a driving member to a slipping member once a preset torque is exceeded.
Friction Clutches can be installed between a motor shaft and a driven mechanism such as a conveyor system. If a jam occurs in the driven system, our slip clutches will protect the motor from burnout and protect the conveyor from additional damage. When installed as a Drag Brake, our clutches maintain tension on a winding operation by exerting drag on the feed spool. As an Overrun Device, these clutches absorb residual inertia of a motor when the load reaches a sudden stop or is braked. Select from our friction clutch models listed below or contact us to discuss customization options.

Adjustable Torque Friction Clutches in Standard and Custom Options

Our slip clutches are available in a variety of adjustable and fixed models. We offer a 30 million slip cycle life, and a temperature range of -4 degrees to 140 degrees Fahrenheit. Custom clutches are available with non-standard bores, keyways, and torques.

Shaft to Shaft Clutches up to 26.6

These adjustable torque friction clutches are ideal for a shaft to shaft connection. The shafts must be supported and aligned within .010-.015. These clutches offer aluminum housing and adjuster ring and a heat-treated steel hub. They have a max recommended slipping speed of 1000 RPM and max backlash of 2°. Options include set screw hub or clamp hub (one end only) styles providing max drag torque up to 26.6 in. lbs.

Component Mount up to 26.6

The shaft mounted clutches are engineered to mount on standard motor shafts, through shafts, sheaves, sprockets, gears, and other standard power transmission components mount. They offer an aluminum housing and adjuster ring, as well as a heat-treated set screw or clamp-style steel hub and sintered bronze bearings. These clutches provide a max drag torque up to 26.6 in. lbs. and a max slipping speed of 1000 RPM.

Shaft to Shaft and Component Mount up to 100

The shaft to shaft and component mount clutches are adjustable torque friction clutches that come in a variety of sizes providing max drag torque up to 100 in. lbs. They are made from durable steel and feature set screw hubs. Our clutches are engineered for long working life, for up to 30+ million slip cycles, and are permanently lubricated.

Clutches with Misalignment Coupling

These couplings feature a set screw fixing and offer system protection and misalignment compensation in one device. Torque reaches to 500 in. lbs. in 7 different sizes, and they have 2-degree maximum backlash. You can use these clutches as torque limiters, tensioners, drag brakes or overrun devices.

Low Backlash Clutches up to 750

These clutches control torque for intermittent, continuous, or overload slip. The clutches will drive in both directions, slip when the torque setting is reached, and resume driving as the load is reduced. Our low backlash clutches are available in adjustable and fixed torque versions. Select from single plate and multi-plate models with a range of torque capacities.

Pneumatic Clutches

Pneumatic clutches from Ondrives.US are adjustable slip friction clutches offering max torque up to 300 in. lbs. They are excellent as continuous drag brakes, protection against accidental or intentional overloads, and for “soft starts.”

Axial Thrust Capable, Adjustable Friction Clutch

The axial thrust capable clutches are adjustable slip clutches with available max torque up to 100 in. lbs. Our slip clutches contain 2 to 12 brass plates interfaced with long-life friction material. They are ideal for driving bottle caps, screws, etc., to exact torque setting.

Technical Notes

Our white papers and technical notes provide additional specifications and selection guidelines for our friction slip clutches and other precision components.
