Advantage:

1. The elastic tensioning device generates a cleaning and tensioning pressure on the conveyor belt scraper that is continuous and prevents rapid belt wear, which can remove small adherent particles.

2. Prevent rapid wear of scraper

3. Effectively absorb the beat of the belt
4. Make sure the surface of the belt is clean

Product Details:

The case size is 45, made of light alloy profile, size 50, made of spheroidal graphite cast iron, and the inner square is made of light alloy profile with four "through holes". The lever can be bolted on one or both sides. Excellent attachments are provided by passing the neutral axis in alternate directions in either direction. All metal parts are painted.

Where To Buy Rosta Swiss AB 45

ROSTA AB type vibration fixing device is a maintenance-free elastic rocker, used to support or suspend free vibration vibration equipment with various designs and drive systems. They assist the driving force in the conveying direction and ensure good linear guidance of the vibration part of the machine. The pantograph structure of the swing bracket allows a larger spring deflection under load, resulting in a lower natural frequency (as low as about 2.2 Hz), so the insulation efficiency of the support structure is extremely high. The excellent lateral stability of the ROSTA vibration mount prevents the screen shell unique to the spiral spring mount from swinging when the resonance frequency is passed.
The bearing seat is made of light alloy profiles and is equipped with lateral fixing flanges, including fixing holes required for direct installation on customer machine parts. Bases AB 45, AB 50 and AB 50-2 have spherical graphite iron feet, which can be directly bolted to the screen and support structure. The shell of the double rubber suspension unit is made of aluminum profiles from AB 15 to AB 45, while the spherical graphite cast iron of AB 50 and AB 50-2 is used. All AB swing mounts can also be made of stainless steel (AISI 304) and can be interchanged with blue AB swing mounts!

Where To Buy Rosta Swiss Products

There are many types of rosta swiss products, we can find them all here, including
1.Nordstrom's shock-proof ESL is designed to absorb low and medium frequencyvibrations and is designed to accept compression, tension and shearloads as well as combined loads. They can be installed in any desired location and are also ideal for ceiling and wall mounting. Due to themechanical fixing principle of the anti-static installation type ESL, it will not tear. These components are maintenance-free, insensitive towater and dirt, and are suitable for temperatures from -40 ° C to + 80 °C. The 45-element housing and core are made of a light alloy with asteel bracket. The size 50 case is made of GGG 40.All components are fully painted.
2.rosta motor base
The Nostar motor base is a 2-in-1 system. It is a motor support and an integrated selftension system. Always maintain ideal belt tension, resulting in constant transmission of rated torque. This extends the life and energy savings of the belts and pulleys .
3. The case size is 45, made of light alloy profile, size 50, made of spheroidal graphite cast iron, and the inner square is made of light alloy profile with four "through holes". The lever can be bolted on one or both sides. Excellent attachments are provided by passing the neutral axis in alternate directions in either direction. All metal parts are painted.

what is a rosta

Rosta meaning is a brand under the Swiss ROSTA AG product line.This is define rosta.

ROSTA AG is located in the central region of Switzerland and was founded in 1944. Mainly engaged in the design, research, production and sales of elastic modules used in mechanical equipment. It belongs to the Swiss POLYGENA Group, and among the many sister companies, it is most closely related to COMPOUNDS AG. Because they design, produce and provide the core components of all ROSTA products-elastomers.

The company's products are mainly divided into three categories, namely: vibration conveying technology, elastic tensioning technology and elastic module technology.

Products include: elastic vibration support, chain belt tensioner, motor elastic tension base, elastic shock absorption products and elastic modules.
The products are used in a variety of industries and mechanical equipment, which can be briefly summarized as: 1) Buffer, shock absorption and vibration isolation on vibration equipment. 2) Automatic tensioning on belt or chain transmission equipment. 3) Bearings, buffers and shock absorption and vibration isolation devices on various mechanical equipment.
