SFC ModelThe SFC model is a metal disk type coupling with lightweight and high-strength aluminum alloy used for the clamp hub. It has a high torsional rigidity and responsiveness. The SFC-SA2 with single element and ultrahigh rigidity and the SFC-DA2 with double elements and flexibility are available. Each type has a green design corresponding to the RoHS.

SFS Model The SFS model are metal disk type couplings. Carbon steel is used for the body material. Very high torsional rigidity assures accurate shaft rotation and ultra precision control. A single element type with high rigidity, double-element type with flexibility (two elements are used through a spacer plate) and floating type with a flange between double elements are available. Assembly finished or partly-finished product, frictional fastening or key fastening of shaft, or taper shaft correspondence is available for each type.

BAUMANN MINI FLEX The ZG and LM models are available. The allowable torque is relatively low, yet it has an excellent flexibility. Especially for the LM model full-length long type (LM-1 type), maximum angular misalignment 14deg. is allowed. The hub and coil spring of ZG model are made of zinc alloy and spring steel. Those of LM model are made of aluminum alloy and stainless steel. It is selectable according to the use environment.

BAUMANN FLEX MM Model By applying a trilaminar structure to the coil spring part, high torque transmission with compact body is possible. The MM-K type uses material corresponding to S35C for the hub and piano wire for the coil spring. The MM-K-S type uses stainless steel for the hub and coil spring. It is selectable according to the use environment.

BAUMANN FLEX MF Model By changing one side of the hubs of MM model to a flange, it meets wider application needs. As well as MM-K type, MF model uses material corresponding to S35C for the hub and piano wire for the coil spring.

SFF,SFM Model The SFM and SFF model are metal disk couplings with high precision and speed control developed for machine tools. The SFM model is designed for a main shaft of machine tool, and the SFF model is designed for a feed shaft of machine tool. For the SFM model, a centering mechanism is set for the pressure flange as well as flange part to respond to a high-precision mounting. To reduce a wind roar during high-speed rotation, the outer circumference of the plate spring is covered with a flange to reduce irregularities of shape. By the newly developed plate spring, both models have a class-leading torque transmission.

SFH Model The Largest Model Among SERVO FLEX : Metal Disk Couplings The maximum flange outer diameter is ø 262 mm and the permissible torque is 8000 N·m. The most rigid S type has a torsional stiffness of 10,780,000 N·m/rad at maximum. This series is available with the high-flexibility G type, where a high-rigidity single-element S type and two elements are positioned respectively and are jointed with a floating shaft at the middle part. This is also available for length setting according to customers' requests.

HELI-CAL A Model It is an integral-structured metal coupling with a single spiral slit in the round material. A perfect integrated construction eliminates backlash. Maximum parallel offset 0.25mm and maximum angular misalignment 5deg. are allowed. The high-strength aluminum alloy material and alumite treated surface ensure a high-corrosion resistance. Two fastening methods can be selected, the set screw method (ARM model) and clamp method (ACRM model).

HELI-CAL 3000(1441) Model It is an integral-structured metal coupling with a single spiral slit in the round material. A perfect integrated construction eliminates backlash. Maximum parallel offset 0.25mm and maximum angular misalignment 5deg. are allowed. Due to the stainless steel material, it can be used in any environment. Two fastening methods can be selected, the set screw method (3002M and 1441 models) and clamp method (3005M model).

HELI-CAL DS Model It is an integral-structured metal coupling with two spiral slits in the round material. It has a higher torsional rigidity compared with the HELI-CAL A model with single spiral slit. A perfect integral construction eliminates backlash. Maximum parallel offset 0.15mm and maximum angular misalignment 3deg. are allowed. The high-strength aluminum alloy material and alumite treated surface ensure a high-corrosion resistance. Two fastening methods can be selected, the set screw method (DSR model) and clamp method (DSCR model).

CENTA FLEX A Model Motive power is transmitted though a high elastic rubber. It is excellent in absorbing vibrations and shocks. Noise of machinery is also reduced. The rubber part is composed of a polygon rubber and aluminum insert inserted at the top, and each part is tightly attached by vulcanizing. Power transmission is accomplished by fixing the rubber body in the hub and flange hub in a radial direction and axial direction respectively by bolts. Especially for a radial directional coupling, a precompressed construction of deformed rubber body enables a power transmission excellent in flexibility and absorbing vibrations and shocks. Rubber parts are available in two types, bolt mounted type (O0) and bayonet mounted type (S0).
