BEM-T Type (Ultra compact)The BEM-T is a compact power supply for the rated voltage DC45/90/180V non-excited brakes corresponding to each input voltage of AC100V, AC200V and AC400V. Simply by connecting and inputting, the required direct current for non-excited brake operation can be obtained. Due to the compact and slim structure, it can be mounted in any place. In addition, the movable mounting part allows for a free selection of input-output direction. A tab terminal (110 series) is set on the output side where the non-excited brake is connected to. Therefore, a connecting space and the number of man-hour can be reduced. Furthermore, the entire case is molded by resin that it can be used in the presence of powder dust. It corresponds to the EU Restriction of Hazardous Substances that bans the use of 6 substances such as mercury or lead.

Only one pressure screw allows easy and quick mounting and dismounting. A pressure medium sealed inside of the chamber is pressurized by fastening the pressure screw, and moves equally into the sleeve. By the pressurization of a pressure medium, the sleeve is pressured from inside to contract the shaft-sided sleeve and enlarge the hub-sided sleeve to fasten a shaft and hub through the sleeve. Since the ETP-EXPRESS uses only one pressure screw to fasten, assembling time of equipment requiring a positioning can be substantially reduced. It is also useful for the place requiring a repetitive mounting and dismounting. A stainless steel specification (ETP-E-R type) resistant to environment is also available as standard.

Since the ETP-TECHNO uses only one pressure screw to fasten, assembling time of equipment requiring a positioning can be substantially reduced. It is also useful for the place requiring a repetitive mounting and dismounting. Furthermore, a high-precision mounting and ultrahigh-precision positioning can be performed due to its excellent concentricity of 0.006 mm. A simple anti-rust specification with electroless nickel plating (ETP-T-C) is also available. ETP-T TypeOnly one pressure screw allows easy and quick mounting and dismounting.

The ETP-T-C type is a simple anti-rust specification with electroless nickel plating.

The clamping bolts placed on the flange surface allow easy and quick mounting and dismounting. A pressure medium sealed inside of the sleeve is compressed by fastening the clamping bolt. By the compression of a pressure medium, the sleeve is pressured from inside to contract the shaft-side sleeve and enlarge the hub-side sleeve to fasten a shaft and hub through the sleeve. Compared with a mechanical-type fastening element, the number of bolts to be used is small. Also, a high-precision fastening is possible with no slotting. A large variety of specifications such as hexagon bolt, simple antirust with electroless nickel plating, stainless steel or short sleeve specification are available.

The POSI-LOCK is a mechanical-type shaft lock joint. Fasting of clamping bolt produces a wedge effect to perfectly fasten a shaft and hub. The PSL-K type with a small inner and outer diameter ratio of the sleeve to reduce diameters of parts, PSL-G type for a general specification and PSL-D type designed for a medium load with a small surface pressure to reduce diameters and weight of mounted part are available. Also, a large variety of specifications such as simple antirust with electroless nickel plating or stainless steel specification are available.

By pressing oil into the sleeve by a pump to move the wedge of built-in taper piston, the sleeve is pressured from inside to contract the shaft-sided sleeve and enlarge the hub-sided sleeve to fasten a shaft and hub tightly through the sleeve. The maximum allowable torque is 2600Nm for a shaft dia. 50mm. Since the oil pressurization has an effect on the taper piston displacement only, no pressure is applied after fastening. The fastening power is maintained only by the wedge effect of the taper piston.

In a word, this product is a shock absorber. The ROSTA is a multifunction and multipurpose product with a unique principle and construction. Three functions, spring, damper and bearing functions, are provided at the same time. It is composed of a metal inner shell, outer shell with 45 deg. of displacement and precompressed cylindrical rubber. In addition to a tensioner, it can be used as a rocking, vibration-proofing equipment or suspension of all industrial machinery based on this suspension unit.

In a word, this product is a shock absorber. It is a multifunction and multipurpose suspension unit with a unique principle and construction. Three functions, spring, damper and bearing functions, are provided at the same time. It is composed of a metal inner and outer shell with 45 deg. of displacement and precompressed cylindrical rubber. Due to the non-linear spring characteristic, an oscillating movement is transmitted reliably to absorb vibrations and noises at the same time. It has an excellent durability to fluctuations and impact loads.

It can be used as tensioners, pressure rollers or dampers by attaching an arm to the ROSTA suspension unit to set a roller or sprocket. The outer shell has a flange shape and can be mounted using only one center bolt. The mounting hole of idlers can be selected depending on the load range (normal/hard) . The SE model with no idler, the belt tensioner RSE model with idler and the NSE model with sprocket idler are available

The vibration isolation mount ROSTA is effective in vibration control for all kinds of machinery. The ESL model corresponding to an intermediate frequency range of eigenfrequency 4.5 to 11Hz and the V model corresponding to a relatively higher frequency range are available. Both models correspond to any mounting direction, also left, light, top, bottom, back and front loading direction.

Rocking mount and drive head supporting a vibration conveyer or sieving machine can be designed by the ROSTA suspension unit. The AU model is a rocking mount allowing direct flange mountings on crank-motion-type vibration conveyers. The RST model is rocking drive head (rod end) allowing a smooth transmission of oscillating movement. By using the AU model in combination with the RST model, an optimum design is possible.

Applicable motors are 0.4kW to 3.7kW (4-pole) and 4 sizes are in the lineup.

Motor Slide BaseA motor slide base for moving the set motor during speed change of the VARI-DIA pulley. Speed can be easily changed by setting the motor-mounted VARI-DIA pulley on the slide base and turning the handle to change the center distance between the motor and driven side.

Intermediate Pulley(L,U,T Model)An intermediate-type variable speed drive is a speed change pulley used between the motor and machine. Two fixed pulleys (cone) are set at both ends of the sleeve and a moving pulley (cone) is set between them. Speed is changed by moving the pulley to the thrust direction to change the pitch diameters of the motor-side and the machine-side intermediate pulleys antagonistically. The L model with lever-operated speed change, U model with handle-operated speed change and T model for user-defined design are available.

When turning the handle of the motor-side speed changer, the width of the speed change pulley will change. By varying the pitch diameter of the speed change belt, the pitch diameter of the machine-side speed change pulley will follow to change the rotation speed. The PDS model is a belt-type stepless speed change drive that is incorporated directly into machines to save space. There are 6 sizes from 0.2kW to 3.7kW (4-pole) of transmission capacity.

The PDC model is a non-stage speed change unit combining a speed changer of the PDS model, motor and driven shaft on the bed. It is a very simple unit suitable for a used-defined design. There are 6 sizes with the motor output 0.2kW to 3.7kW (4-pole).
