Large jaw couplings are now being offered for bore sizes up to 1-3/4” or 45 mm and torque capacities of 2,655 in-lbs (300 Nm). These new large jaw couplings are designed for use in precision systems with high deceleration and acceleration curves, such as those found in semiconductor, solar, conveyor, and warehouse automation applications.
Explore More >>Pre-assembled modular mounting systems are designed for adjustability across many mounting applications. Conveyor mounting systems emphasize strict parallel installation using a flange-bolt base and a conveyor rail guide. Sensor mounting systems offer flexibility in a mounting application with adjustable or 90-degree connectors, two-way bases, and various mounting brackets. Both systems include stainless steel rods (with or without scale) from 100mm to 300mm in length, zinc clamping levers, and connectors that allow adjustment of the rods’ position.
Explore More >> 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.

| Performance Specifications | |||
|
Rated Torque Recommended torque based on slippage on the shaft. |
2 Nm |
Angular Misalignment Max angle of the shaft axes relative to each other. |
1.5° |
|
Peak Torque The torque where the insert will permanently deform and lose elasticity. This will result in loss of zero-backlash. |
3 Nm |
Torsional Stiffness Measures the rigidity of the coupling. The more rigid the coupling, the less windup it will have. |
1.70 Nm/Deg |
|
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. |
0.70 mm |
Parallel Misalignment Shafts are parallel to each other, but not in-line with each other. They are offset. |
1.00 mm |

Maximum Speed |
15,000 RPM |
Recommended Inserts Any of these inserts will match this coupling hub. |
|
|
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 |

| Product Notes | |||
|
Note 1 |
Stainless steel hubs are available upon request. |
Note 2 |
Performance ratings are for guidance only. The user must determine suitability for a particular application. |
|
Note 3 |
Torque ratings for the couplings are based on the physical limitations/failure point of the inserts. Under normal/typical conditions the hubs are capable of holding up to the rated torque of the inserts. 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. Keyways are available to provide additional torque capacity in the shaft/hub connection when required. Please consult technical support for more assistance. |
