Engineering Calculators Built by Engineers 

Engineering often comes down to making informed decisions with the information available. Whether you’re designing a new system, reviewing an existing application, or troubleshooting equipment in the field, having access to quick calculations can save time and provide useful insight. 

That’s why we’ve developed a collection of engineering calculators focused on rotary unions, hydraulic swivels, rotary manifolds, and fluid transfer systems. These tools are designed to help engineers estimate performance, compare operating conditions, and better understand how different variables affect a system. 

Pressure Drop & Heat Generation Calculator 

Pressure loss and heat generation can affect the way a hydraulic system performs. Higher pressure drops can reduce efficiency, while heat buildup can influence fluid characteristics and component life. 

The Pressure Drop & Heat Generation Calculator allows you to estimate pressure losses and heat generation within a rotary union or hydraulic swivel based on your operating conditions. 

This calculator can help you: 

  • Estimate pressure drop across a component 
  • Evaluate heat generated during operation 
  • Compare different flow and pressure conditions 
  • Review potential performance impacts before equipment is built or installed 

It’s a useful starting point when evaluating hydraulic system behavior and operating efficiency. 

Bolted Joint & Clamp Force Calculator 

Bolted connections are found throughout hydraulic and mechanical equipment. Understanding the relationship between tightening torque, bolt preload, and clamp force can help when reviewing assembly requirements or checking an existing design. 

The Bolted Joint & Clamp Force Calculator estimates bolt preload, clamp force, and tightening torque for bolted connections. 

Common uses include: 

  • Estimating bolt loading 
  • Reviewing fastening requirements 
  • Comparing different bolt sizes and torque values 
  • Evaluating mechanical joint performance 

Whether you’re working on a rotary union, hydraulic swivel, or another mechanical assembly, this calculator provides a quick way to review fastening loads. 

Rotary Manifold Torque Calculator 

Rotational torque is an important consideration when selecting motors, drives, bearings, and support structures for rotary equipment. 

The Rotary Manifold Torque Calculator estimates the rotational torque generated within a rotary union or hydraulic swivel based on operating pressure and application conditions. 

Engineers often use this tool to: 

  • Estimate operating torque 
  • Compare application conditions 
  • Review drive system requirements 
  • Better understand loading within rotating equipment 

A simple torque estimate can provide valuable information during both design and troubleshooting. 

Rotary Seal Life Estimator Calculator 

Seal wear can influence maintenance schedules, operating costs, and equipment uptime. Understanding how operating conditions may affect seal life can help when planning service intervals or comparing design options. 

The Rotary Seal Life Estimator Calculator provides predictive wear-life estimates for rotary manifold sealing systems. 

This tool can help you: 

  • Estimate expected seal life 
  • Compare different operating conditions 
  • Support maintenance planning 
  • Evaluate how pressure, speed, and duty cycle may affect seal wear 

While actual service life will vary by application, the calculator can provide a useful reference point during the evaluation process. 

Designed for Practical Engineering Use 

These calculators were developed by engineers who work with rotary unions, hydraulic swivels, and fluid transfer systems. Rather than replacing detailed engineering analysis, they provide quick estimates that can help guide design decisions, application reviews, and troubleshooting efforts. 

Whether you’re working on a new project or reviewing equipment already in service, these tools offer a convenient way to perform common calculations without building your own spreadsheets or manual calculations.
