It is understood that there is an increasing demand for conveyors in various industries both domestically and internationally, and the market demand for powered roller conveyors is also on the rise. As an important component of such conveyors, the scale of production of powered rollers by different companies is quite significant. A powered roller is a cylindrical component that drives the conveyor belt or changes its direction of movement. These rollers typically feature specially designed steel bearing housings and precision bearings, and their durability, low cost, and flexibility in handling make them well-known in the conveyor industry. Powered rollers are suitable for use in gravity-fed conveyor systems as well as dynamic storage systems, and they are often employed in factories, warehouses, and logistics centers. Based on the barrel material and manufacturing method, drive rollers can be divided into cast drive rollers and welded drive rollers. There are various types of drive rollers; next, let’s focus on the explanations for the code designations of these different types of drive rollers. Code for power roller drive type: The codes for power roller drive types include fixed-axis gear drive (D) (fixed-axis gears with hard tooth surfaces are denoted by A), cycloidal pinion drive (Z) (those with a power of 30 kW or less are denoted by B), and planetary gear drive (X). Installation style and cooling method of the drive drum motor: When the drive drum motor is built-in, its cooling method is generally indicated as either oil-cooled (Y) or immersion-cooled (J). When the drive drum motor is installed externally, the motor installation types are indicated as horizontal motor in series (WI), vertical motor directly connected (WII), and horizontal motor in vertical configuration (WIII). Inclined installation of the drive drum: When it is necessary to install the drive drum at an angle, that is, when the bottom surface of its support forms an angle with the ground or horizontal plane, then an angle value must be indicated as a subscript after the code specifying the motor installation type or cooling method; “left” or “right” should be added in front of this value. The method for determining this is to look from the cable outlet end in the case of an internal installation, and from the rear end of the motor in the case of an external installation. If the drive drum is tilted to the left, it is denoted as “left”; if it is tilted to the right, it is denoted as “right”. If not specified, it is often assumed to be installed in a normal (horizontal) position. Since this factor has a direct impact on the performance and lubrication characteristics of the drive roller, it is essential that users clearly specify it in the contract when selecting a model for the drive roller. Special performance codes for drive rollers: The special performance codes for drive rollers include general type (T may not be indicated), check-type (N), mobile type (YI or YII), explosion-proof type (B), corrosion-resistant type (F), etc.; for externally mounted drive rollers, subscripts can also be used ； Elastic pin coupling type (G), hydraulic coupler type (Y), electro-hydraulic block brake type (Z).
