Tandem roller bearing M2CT89190 88.9x190.5x107.95mm for plastic extruder gearbox

 

Tandem bearings M2CT89190 consist of several axial cylindrical roller bearings arranged in line, A system of rings and washers matched to each other ensures that all stages of the tandem bearing are subjected to uniform load at all times irrespective of the ratio C/F. The rings and washers are made from hardened steel. Tandem bearings are predominantly fitted with standard axial cylindrical roller and bearing assemblies. The thrust cylindrical roller bearing M2CT89190 with size 88.9x190.5x107.95mm, the inner diameter:32 mm, the outer diameter:78mm, the total height:57.5mm

JinHang Precision bearing offer Tandem thrust cylindrical roller F‐53043 bearings have the characteristics of small radial cross-sectional size, compact structure, large axial load capacity, uniform load of each row of rollers, wear resistance, low vibration noise and long life. They are parallel twin screw extruders. Ideal screw spindle bearing.
The tandem bearing including two, three, four, five, six, seven or eight rows of tandem bearings in the company's sample according to the screw center distance, space and load size. The company also accepts tandem bearings of sizes and structures other than the sample.

 

M2CT89190 88.9x190.5x107.95mm application as following:


Tandem thrust cylindrical roller bearings have a limited radial cross-section, super axial load capacity, long-term working life and minimum friction loss, so they are obtained in the parallel twin screw extruder gear transmission box in the rubber and plastics industry Very successful application. It will also be popularized and applied in other mechanical equipment.

There are two major types of extruders; single and twin screw (co-rotating and counter rotating). These come with a wide range of screw diameters (D), lengths (L), and designs. The single screw and co-rotating twin screw are inherently axially open-channel extruders. They can be regarded as drag flow pumps. Their output or degree of fill (if not running at maximum volumetric rate) can be impacted by the pressure flow within the extruder. Closely intermeshing counter-rotating twin screw extruders form closed channels in the intermeshing region. Their output is less vulnerable to the pressure flow within the extruder. As such, they can be considered as positive displacement pumps.
Food extruders utilize thermal and mechanical energy. Understanding energy consumption and input requirements is very important for improving performance and economical system design. Water is a common ingredient in almost all food extrusion formulations. It impacts the characteristics of the ingredients, melting behavior, and formed dough rheology. Part of this water can be sometimes applied in the form of steam, thus impacting the total extruder energy input, extruder output, system design, and operating conditions. Both forms of water can be directly metered into the extruder and/or into a preconditioning mixing device. The steam incorporation option can have a significant impact on the extruder selection, design, and performance, as well as on the product characteristics.

The extruder's important design parameters include appropriate selection of the screw elements and barrel sections. The screws and barrel design impact their functional performance, namely conveying, mixing, melting, and metering, as well as the product characteristics. In practice, one may be able to suggest more than one system design and operation to make the same product. The optimum selection is likely to be governed by availability, flexibility, and economics.

An extruder is basically a screw pump; the screw(s) rotates in a tightly fitting stationery barrel. The semimoist feed or dry powder/grit is introduced into the extruder, usually at a constant rate of mass or volume employing a feeding mechanism. The material thus moves forward by the rotation of the flighted screw(s). Heat is usually supplied externally to the extruder barrel, and is partly produced by viscous dissipation of mechanical energy. The control of temperature is required at different sections of the extruder and at the die end. The material thus undergoes several unit operations like mixing, compression, shearing, and cooking inside the extruder, and is finally shaped in the die through which the material is forced to exit under pressure.

Many types of extruders are used in the food industries and several designs are possible for a food extruder. The most commonly used extruder consists of the flighted screw(s) or worm(s) rotating within a sleeve or barrel to be termed as the screw extruder. However, the piston type extruders are possible though they are used in other type of industries. The flights on the screw push the plasticized material forward and discharge through an opening or the die. The details on the different type of extruders and their components are available (Harper, 1981; Yacu, 2012).

A variety of extruders have been developed to manufacture different types of food products. On the basis of the number of the screw, extruders can be classified as a single-screw or twin-screw extruders. The twin-screw extruder is partially developed on the experience and the knowledge derived from the understanding of single-screw extrusion cooking.

A conventional single-screw extruder usually has three sections: feed, transition, and metering zones. The extrusion screws sequentially convey the incoming feed in the feed section, and heats the feed to form a continuous plasticized mass (in transition and metering sections), while rotating in the barrel. The screw can be designed either as a single piece or as several small segments. Twin-screw systems are costlier and more complex than the single-screw extruders. However, the twin-screw extruders are preferred by food industries due to improved mixing abilities, uniform temperature distribution features, facility to control the feed residence time, and enhanced positive displacement capacity. The twin-screw extruders, on the basis of rotation, can be categorized as counter-rotating and corotating twin-screw extruders. The food industries prefer fully-intermeshing corotating twin-screw extruders because of several technological features, particularly, the better control of machine and product, and the efficient operation during extrusion cooking.
