Machine for handling sheetlike material, such as a printing press and a sheet feeder therefor, having a combined inductivecapacitive probe for discriminating among the presence of a single thickness of the sheetlike material, the absence of the material, and the presence of excessively thick sheetlike material, such as two or more superimposed sheets, or for determining the moisture content of the sheetlike material. The probe is substantially insensitive to machine vibrations.
Inductive sensors use a magnetic field to detect objects. Capacitive sensors use an electric field. In order to be sensed by an inductive sensor an object must be conductive. This limits suitable targets to metal objects (for the most part!. In order to be sensed by a capacitive sensor the target doesn't need to be conductive. A capacitive sensor will react to an object acting as a dielectric material as well as a conductive object. This makes metal and non-metal objects suitable targets
Mounted Ball Bearing Units
Ball bearing units consist of an insert bearing mounted in a housing. An insert bearing is a deep groove ball bearing with a sphered (convex) outside surface and an extended inner ring that includes a mechanism to lock the unit onto the shaft. The housings have a correspondingly sphered but concave bore.
The self-contained bearing features a spherical ground outside diameter bearing that is assembled into a corresponding spherical housing seat, providing full self-alignment of the bearing unit.
A set-screw locking mechanism is shown in the bearing cutaway above; this is the most popular method of locking the bearing insert onto a shaft. Bearings with adapter sleeves,
eccentric and concentric locking collars are also available.
For set-screw locking types, the inner ring of the self-contained bearing is hardened in the raceway and surrounding areas, where hardening is necessary, while the extended part where the set-screws are located is left metallurgically softer and slightly more flexible. This special heat treatment method
ensures maximum bearing performance, while preventing the set-screws from loosening during operation, because the set-screws can be tightened as needed without causing destructive inner ring cracking.

Engineering Class Chains
Do you need to elevate, convey, operate or drive something? Then you probably need an engineering chain. These jack-of-all-trades chains provide superior strength, durability and endurance and are built to be continually reliable under some of the toughest conditions on the planet. Drive chains are designed to offer exceptional fatigue strength and even a reserve of strength to handle those heavy loads and rugged conditions. Engineering chains help keep projects of all sizes moving smoothly and rapidly — keeping projects on track and profits flowing smoothly.
Details in specifications ...
In your industrial application, knowing that your chains are sturdy enough to survive the harshest tests in terms of load, shock and strain is critically important. Any time that your production line is down, you are not making money — and to have the problem traced back to a lowly engineering chain is simply unacceptable. That’s why the engineering chains that PEER Chain provides are only the highest quality, pre-tested for optimum strength and crafted with alloy steel parts for accurate pitch control and exceptional press fit. The uniform core strength that you’ll find in these engineering chains allows them to continue to deliver consistent results for your project day after day, night after night of uninterrupted service.
Uses of Engineering Chains
Food service is only one of the many applications for this versatile class of engineering chains. They are used for some of the toughest applications such as drilling for oil, operations that include a lot of sand, dirt and sticky crude oil. They also see usage on forklift trucks where they’ll be subjected to numerous repetitions of stress and jolts. Engineering chains are the go-to option for engineers when the application requires a compact space with the maximum possible amount of power transfer and a high level of durability.
High Quality Gears & Conveyors
A gear reducer is a mechanical transmission device that connects a motor to a driven load. It is also known as a gearbox. It allows you to modify the torque and speed between a motor and a load. Reduction gear assemblies are made up of series of gears. The gear reduction ratio (the ratio of the number of teeth between input and output shafts) is also known as the transmission ratio.
A gear reducer is used to adapt the characteristics (torque and speed) of the input and output axis of a mechanism. This is why you have to know the torque and rotation speed.
It is therefore appropriate to ask yourself about the torque first and foremost. A reducer increases the torque of your motor and thus allows a receiving member to rotate under the impact of a new torque. Gear reducer manufacturers sometimes indicate the minimum and maximum torque (expressed in newton meters, N.m) that can be supported by each of their products. The torque density varies according to the gear reducer. For example, planetary gearboxes have a high torque density.
The other purpose of a gear reducer is to reduce the motor speed and we recommend that you take into account the ideal reduction ratio for your use. Based on the rotational speed of your motor, the reduction ratio is used to determine the output rotational speed. This information is also indicated by manufacturers on their product pages. It is given in revolutions per minute.
Lastly, you should ask yourself what kind of gear reducer assembly is most appropriate for your application. The input and output shafts of your gear reducer can be coaxial, parallel-shaft or orthogonal. This depends on your intended use.
