About HUB CITY

Hub City's extensive catalogue includes speed reducers, gear drives, bearings, couplings and related parts & accessories. The brand's splined shafts work with splined shafts and are used in pumps and gearboxes. These Hub City couplings offer higher torque than round / keyed shaft couplings. They feature a spider-shaped cushion between two hubs for absorbing shock and handling minor shaft misalignment. They have a low alloy / high carbon steel body for structural rigidity and durability. The brand's C-face space reducers offer an optional base for flexibility in installation. These are designed for industrial-duty applications, ensuring reliability in demanding environments. Featuring a 56C frame, these space reducers offer a standardised and versatile mounting option. They have 8620 steel construction for improved longevity and performance. These C-face space reducers utilise a helical-hypoid type gear for smooth and efficient power transmission.

HUB CITY Competitive Advantages

HERA gear drive

HERA is a gearbox that efficiently transfers power at a 90-degree angle. It is used for mechanical systems, automotive parts and industrial applications to transmit power and torque efficiently at right angles. This gear drive is available in cast iron / stainless steel for enhanced durability. It comes with a generic bolt pattern on mounting surfaces for straightforward replacement in worm gear drives. This Hub City gearbox accepts input from solid shaft / quill-style motor frames for enhanced compatibility with different motor types and sizes. This gearbox is factory-filled with food-grade PAG oil to ensure proper lubrication for reliable operation. It has a Viton seal for added protection against contaminants and can be paired with premium-efficiency Marathon (XRI) motors to maximise system efficiency.

CleanLine Gear Drives & Washdown Products

CleanLine gear drives and washdown products are used in food processing, pharmaceuticals and industries requiring sanitary equipment. They resist corrosion and contamination. They include gear drives, motors and accessories in their product line. They feature acrylic-painted housings and stainless steel shafts. These CleanLine Plus gear drives have aluminium Platinum Plus housings and stainless steel shafts. Hub City stainless steel gear drive design in CleanLine UltraPlus drives goes beyond basic corrosion resistance and offers a smooth unobstructed, contoured exterior surface. They are free of ribs, undercuts and protrusions that hinder washdown, cleaning and sanitary conditions. CleanLine UltraPlus Hub3 gear drives are equipped with stainless steel housings, shafts and hardware. These drives are available in 7 different sizes of worm gear reducers. Smooth polished surfaces all around make them the ultimate food processing and washdown solutions.

Frequently Asked Questions

What are the factors to consider while selecting the right Hub City spline shaft or coupling for my application?

Major factors include torque requirements, shaft type & size, misalignment tolerance, speed and temperature.

What is the difference between spline shafts and gears?

Splines and gears are both designed to transmit torque and have external teeth that engage with a mate component. Splined shafts differ from gears in a way that they transfer torque using all teeth or grooves at the same time.

What is the use of a spline joint?

A spline joint is used to strengthen and align the edges. A spline can be used in place of a tongue and groove. The spline, when used on a mitre joint, adds extra strength to an otherwise delicate joint. The spline is also useful for aligning the two joining parts during assembly and glue-up.

What is a gear drive and how does it work?

A gear drive is a mechanical device used to transmit power from one component to another using gears. It works by meshing the teeth of two or more gears to transfer rotational motion and torque.

What factors should I consider while choosing a Hub City coupling?

  • Determine the specific application and whether you need a flexible, rigid or specialised coupling.
  • Calculate the torque and misalignment capacity needed for your application.
  • Consider the speed and rotational requirements to ensure the coupling can handle them.
  • Account for factors like temperature, moisture, and potential corrosive environments.
  • Assess the available space for installation and whether a compact design is required.
  • Evaluate maintenance requirements and select couplings that align with your maintenance strategy.
  • Balance performance requirements with your budget constraints.
  • Explore Hub City's coupling product range to find the most suitable model.
  • If uncertain, consult Hub City's technical support or distributor for guidance.
  • Review product specifications and documentation for compatibility and technical details.

How do I clean and maintain Hub City reducers?

  • Shutdown the equipment and ensure it is safely turned off.
  • Remove dirt, debris and contaminants from the reducer's exterior using a brush or compressed air.
  • Check seals for wear or damage; replace them if necessary to prevent leaks.
  • Follow the manufacturer's guidelines for proper lubrication and ensure the reducer has adequate lubricant.
  • Periodically check and adjust the reducer's alignment to prevent excessive wear.
  • Monitor operating temperatures to detect overheating, which can indicate a problem.
  • Regularly analyse vibration levels to identify potential issues or misalignment.
  • Establish a maintenance schedule and conduct routine inspections based on manufacturer recommendations.
  • Keep records of maintenance activities and adhere to the manufacturer's maintenance manual.

When should I replace Hub City gear reducers?

  • Excessive wear
  • Increased noise
  • Reduced efficiency
  • Frequent failures
  • Beyond service life
  • Safety concerns
  • Obsolete models
