Mountable shaft collars with face holes are designed to mate directly with components such as sprockets, pulleys, and metallic plates. Ruland manufactures them with drilled holes for mounting flexibility or threaded holes for the most secure connection between the collar and mated component. They are offered in steel, aluminum, and 303 stainless steel in bore sizes ranging from 3/8” to 2” and 10mm to 50mm.
Explore More >> Clamp style universal joints improve over set screw style because they do not mar the shaft, offer infinite adjustability, and can be used on all shaft types. Ruland is the only North American supplier of clamp style universal joints and manufactures the clamp feature, bores, and keyways in our advanced manufacturing facility in Marlborough, MA USA. They are available in sizes from 1/4" to 1 1/4” in steel for high strength and stainless steel for corrosion resistance.

Angular Misalignment Max angle of the shaft axes relative to each other. |
0.5° |
Parallel Misalignment Shafts are parallel to each other, but not in-line with each other. They are offset. |
0.008 in (0.20 mm) |
|
Max Parallel Misalignment Oldham couplings can exceed the standard parallel misalignment rating without additional bearing loads. When using at the max rating, life cycle of the insert may be impacted. The user must test for suitability. |
0.131 in (3.33 mm) |
Axial Motion The amount shafts can move closer to or away from each other. This is meant for thermal expansion of the shafts. No axial force can be placed on the coupling. |
0.006 in (0.15 mm) |

Torsional Stiffness Measures the rigidity of the coupling. The more rigid the coupling, the less windup it will have. |

Full Bearing Support Required? Full bearing support is a bearing in close proximity to both sides of the coupling to prevent axial loads that could result in rapid coupling failure. |
Yes |
|
Zero-Backlash? Zero-backlash ensures there is no loss of motion during operation. |
Yes |
Mechanical Fuse? The disc is designed to break at a certain torque. When it reaches the torque, it breaks and power transmission stops. |
Yes |

| Product Notes | |||
|
Note 1 |
Performance ratings are for guidance only. The user must determine suitability for a particular application. |
Note 2 |
Torque ratings for the couplings are based on the physical limitations/failure point of the torque disks. Under normal/typical conditions the hubs are capable of holding up to the rated torque of the disks. In some cases, especially when the smallest standard bores are used or where shafts are undersized, slippage on the shaft is possible below the rated torque of the disks. Keyways are available to provide additional torque capacity in the shaft/hub connection when required. Please consult technical support for more assistance. |
