Industrial Component Selection Guides
Selecting an industrial component begins with the application, not the catalog. OpenType selection guides organize the dimensions, interfaces, loads, ratings, materials, environmental conditions, controls, and service requirements that should be understood before comparing candidate components.
Start With the Application
Before choosing a fastener, bearing, motor, valve, connector, or sensor, define what the component is expected to do and the conditions under which it must operate.
Industrial Component Selection
The master guide for turning an application into a practical component specification.
Define requirements before comparing products.
The Industrial Component Selection Guide provides a general process that applies across mechanical, electrical, fluid-power, motion, and automation components.
- Define the component's required function
- Record physical and mounting constraints
- Identify operating loads and ratings
- Specify materials and environmental conditions
- Identify control and system interfaces
- Compare candidate specifications
- Verify compatibility before installation
Component-Specific Selection Guides
Each guide focuses on the specifications and application conditions that matter most for a particular industrial component family.
Fastener Selection Guide
Select bolts, screws, nuts, washers, and related threaded fasteners based on joint geometry, loading, threads, strength, material, finish, and installation.
Thread · strength · joint · material · environment
Bearing + Bushing Selection Guide
Compare motion type, load direction, speed, shaft dimensions, housing dimensions, fits, lubrication, materials, sealing, and alignment.
Load · fit · speed · lubrication · alignment
Motor + Drive Selection Guide
Define torque, speed, power, acceleration, duty cycle, gearing, electrical supply, mounting, control, feedback, and machine-load requirements.
Torque · speed · power · duty · controls
Pump + Valve Selection Guide
Select fluid-handling components by evaluating media, flow rate, pressure, temperature, materials, seals, connections, control function, and actuation.
Fluid · flow · pressure · material · actuation
Electrical Connector Selection Guide
Compare voltage, current, conductor size, contact arrangement, housing geometry, keying, termination, shielding, sealing, and mating requirements.
Voltage · current · contacts · geometry · sealing
Sensor + Control Selection Guide
Select measurement and control components by defining range, accuracy, response time, output signal, power, mounting, environment, wiring, and control integration.
Range · accuracy · signal · mounting · integration
The OpenType Selection Method
Although the specifications change by component family, the basic selection process remains consistent.
Define
Identify what the component must do within the machine, process, electrical system, or assembly.
Specify
Convert the application into measurable requirements: dimensions, loads, ratings, interfaces, materials, controls, and environmental limits.
Compare
Review candidate drawings, data sheets, part-number options, materials, performance ratings, and technical documentation.
Verify
Confirm that the selected component fits, functions, and integrates correctly under the real operating conditions of the application.
What to Check First
Every component family has a different starting point. These first checks quickly eliminate candidates that cannot satisfy the basic application requirements.
New Design vs. Replacement Selection
Component selection is different when designing a new machine than when replacing a part in an existing one.
Start from system requirements.
A new design gives the engineer more freedom to select dimensions, interfaces, materials, controls, and standardized components that support future sourcing and maintenance.
- Define the required machine function
- Calculate loads and operating conditions
- Choose practical standardized interfaces
- Consider more than one supplier where possible
- Design for installation and service access
- Document the final component requirements
Start from the existing interface.
Replacement selection is constrained by the existing machine. Critical dimensions, mounting, wiring, piping, controls, performance, and environmental requirements may already be fixed.
- Document the installed component completely
- Identify which specifications cannot change
- Compare candidates specification by specification
- Investigate every material or rating difference
- Verify control and system integration
- Classify the candidate as direct or modified replacement
Technical References for Better Selection
Selection depends on understanding the component, interpreting its specifications, and determining whether it is compatible with the intended application.
