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.

| Performance Specifications | |||
|
Dynamic Torque Reversing Max torque when coupling reverses direction without stopping. |
0.35 Nm |
Angular Misalignment Max angle of the shaft axes relative to each other. |
2.5° |
|
Dynamic Torque Non-Reversing Max torque for the coupling during quick changes in acceleration or deceleration. |
0.55 Nm |
Parallel Misalignment Shafts are parallel to each other, but not in-line with each other. They are offset. |
0.08 mm |
|
Peak Torque The torque where the insert will permanently deform and lose elasticity. This will result in loss of zero-backlash. |
0.80 Nm |
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. |
0.30 mm |
|
Torsional Stiffness Measures the rigidity of the coupling. The more rigid the coupling, the less windup it will have. |
0.8 Nm/Deg |

|
Maximum Speed |
12,000 RPM |
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 |
Balanced Design The balanced design allows for reduced vibration at high RPMs. |
Yes |
