English roller chain sprockets engage chains in many different power transmission and conveyor systems. Sprockets and chains are often an economic, reliable drive system for long running, continuous drive applications with limited shock and torque loads. English sprockets are classified according to ANSI number designations.

Ball bearings are used to provide smooth, low friction motion in rotary applications. Ball bearings types include radial ball bearings (deep groove and angular contact) and thrust ball bearings.
|
|
Ball screws, lead screws, and ACME screws are used to convert rotary motion or torque into thrust or linear motion.
|
|
Ball slides are simple linear motion devices that provide smooth linear motion, accurately controlled by the rotation of the drive mechanism.
|
|
Bevel and miter gears have conical faces that operate on intersecting axes. Miter gears are bevel gears with a 1:1 ratio operating on right axes.
|
|
Flexible couplings connect rotating members while allowing some degree of angular or parallel misalignment.
|
|
Gearboxes and gearheads are speed reducers that consist of a set of gears, shafts, and bearings in an enclosed housing. In converting inputs to outputs, they reduce RPM and increase torque.
|
|
Gears are mechanical devices that transmit power and motion between axes.
|
|
Helical gears transmit power and motion between parallel axes (opposite hand) or right-angle axes (same-hand).
|
|
Herringbone gears use teeth with two opposing helices and transmit power and motion between parallel axes. They sometimes have a center groove.
|
|
Hypoid gears have specially formed teeth on a circular face that are driven by a worm-like drive on non-intersecting axes.
|
|
Industrial pins are cylindrical fasteners that are used to locate, align and join components. They are made out of aluminum, brass, titanium, wood and plastic. Products made from hardened steel, unhardened steel, and stainless steel are also available.

Metric roller chain sprockets engage chains in many different power transmission and conveyor systems. Sprockets and chains are often an economic, reliable drive system for long running, continuous drive applications with limited shock and torque loads. Metric sprockets are classified according to ISO number designations.

|
Linear bearings are used in applications where a component needs to be moved along a straight line with high accuracy.
|
|
Linear shafts are elongated, rod-shaped devices that provide linear or rotary motion for power transmission applications.
|
|
Linear slides are simple linear motion devices composed of a stationary base and a moving carriage. Linear stages are slides with a drive mechanism that provide controlled, precise positioning along a linear axis.
|
|
Miniature bearings and instrument bearings carry moderate radial and thrust loads at low operating torque while providing high performance in a small envelope design. These types of bearings are single row ball bearings available in up to 1 1/8" outer diameter (OD) sizes
|
|
Plain bearings and sleeve bearings (also referred to as bushings or journal bearings) are used to constrain, guide or reduce friction in rotary or linear applications. They function via a sliding action.
|
|
Posts, spacers, and standoffs are threaded and used in applications where boards, plates, or other items need to be fastened to each other.
|
|
Precision shafting provides the highest degree of overall accuracy, concentricity, straightness and surface perfection attainable in commercial practice.
|
|
Rack and pinion gears are used to convert rotation into linear motion.
|
|
Radial or deep groove bearings can handle radial and axial loads to varying degrees, but are typically used when the primary load is in the radial direction.
|
|
Retaining rings and snap rings are fasteners used to axially position a component on a shaft or in a bore.
|
|
Roller chains are used in many power transmission designs. They are characterized by ANSI and BS/DIN standard sizes.
|
|
Incremental rotary encoders are multi-turn sensors that use optical, mechanical, or magnetic index-counting for angular measurement. They contain no absolute reference, but instead count relative to the turn-on position.
|
|
Screws are fasteners that consist of a threaded shaft at one end and, typically, a head at the other. They are inserted into solid materials and secured via rotation.
|
|
Shaft collars attach to shafts and are used as stop features or targets for devices such as tachometers.
|
|
Specialty or proprietary products and accessories related to gear types.
|
|
Spur gears are straight-toothed gears with radial teeth that transmit power and motion between parallel axes.
|
|
Stepper motors use a magnetic field to move a rotor in small angular steps or fractions of steps. They provide precise positioning and ease of use, especially in low acceleration or static load applications.
|
|
Timing belts are transmission drive belts with teeth for efficient, high-power synchronous drives. Metric pitch is the distance between belt teeth based on millimeters.
|
|
Timing pulleys mesh with same-pitch timing belts on synchronous drives where maintenance of speed ratio is important. Metric pitch pulleys have a millimeter-based pitch designation.
|
|
Torque limiters and slip clutches automatically slip or disengage the clutch at a predetermined torque.
|
|
Universal joints are flexible mechanical connections used to transmit rotary motion from one shaft to another shaft that is not in line with the first, or when alignment varies during service.
|
|
Worm gears are cylindrical gears with a spiral thread that drive mating worm wheels in high-reduction gearset applications. They operate on non-intersecting perpendicular axes.
