The information provided under Principles of bearing selection and application is general and applies to most super-precision bearings Information specific to one bearing type is provided in the relevant product section Angular contact ball bearings Ball bearing The most popular type of ball bearing has a single row of balls In addition to the single row design there also are double row angular contact and ball thrust bearings The characteristics and uses of each type will be covered in Chapter Five Roller bearing One variation of roller bearings – the tapered roller – is used

Screw Thread Cutting

Screw thread terminology A metric measurement lathe has a quick-change gear box used to set the proper screw pitch in millimeters An inch- designed lathe must be converted to cut metric threads by switching gears in the lathe headstock according to the directions supplied with each lathe A formula by which the proper size wire may be

A DC motor is any of a class of rotary electrical motors that converts direct current electrical energy into mechanical energy The most common types rely on the forces produced by magnetic fields Nearly all types of DC motors have some internal mechanism either electromechanical or electronic to periodically change the direction of current in part of the motor

There is a tremendous variation in boiler design and size- ranging from home heating size of capacity less than 100 Ibm/hr of steam to utility boilers in excess of 10 million Ibm/hr The focus here will be on boilers sized in between these two extremes which is also where there is the greatest diversity of design

Acme and Lead Screw Products Precision Acme and Lead Screws Nook Industries manufactures precision acme and lead screws by thread rolling thread milling or thread grinding processes Each process produces high precision screws Nook acme screw systems feature centralizing thread forms for smooth no-wedging performance

Generally speaking DC motors are less expensive than their AC counterparts These are also servo motors that have been built specifically for continuous rotation making it an easy way to get your robot moving They feature two ball bearings on the output shaft for reduced friction and easy access to the rest-point adjustment potentiometer

ASTM's petroleum standards are instrumental in the evaluation and assessment of the physical mechanical rheological thermal and chemical properties of crude oils lubricating grease automobile and aviation gasoline hydrocarbons and other naturally occurring energy resources used for various industrial applications

This is because the spur gear can be really loud Each time a gear tooth engages a tooth on the other gear the teeth collide and this impact makes a noise It also increases the stress on the gear teeth To reduce the noise and stress in the gears most of the gears in your car are helical

End milling - An end mill makes either peripheral or slot cuts determined by the step-over distance across the workpiece in order to machine a specified feature such as a profile slot pocket or even a complex surface contour The depth of the feature may be machined in a single pass or may be reached by machining at a smaller axial depth of cut and making multiple passes
