Custom Bearings

Our custom bearing designs and modifications are tailored to thrive in unique applications.

When confronted with a design challenge, a cataloged bearing is not always a suitable option. Carter is a leading supplier of custom bearings with full technical services to support the most extreme environments. Whether it is modifying a standard product or a completely bespoke proposal, Carter can rely on decades of proven solutions with access to cutting-edge technology.
 

ADVANTAGES

Anti-Rotation Features

Anti-rotation features are commonly added to remove any relative motion between the bearing and its mating components. These features can be added to standard bearings or designed specifically into a custom bearing. There are many options and Carter bearing experts will determine which is suitable for your application.

Internal Clearance Adjustments

The bearing internal clearance can be adjusted if the application requires increased clearance due to high temperatures or an internal preload to reduce radial or axial movement.

Relubrication

  • Lubrication modifications is a very common service at Carter Bearings. No batch is too small to relubrication standard bearings with unique lubrications for ultra-high vacuum, food grade, low temperature, high temperature and many more.
  • Learn more at Specialist Coatings and Lubrications.

Oil Holes and Grooves

Features can be designed into the bearing to control the lubricate rate at high speeds.

Unique Geometry

Completely custom bearing designs can be provided with engineering support and lifetime evaluation.

Exotic Materials

One of the most common reasons for a custom bearing is the material.  With bespoke bearing designs, any material can be utilized for improve lifetime characteristics due to corrosion resistance, fatigue strength, high temperature hardness, cryogenic temperature compatibility and many more. Consulting with bearing experts at Carter will reveal if a material upgrade will provide value to your final product.

Precision Modifications

  • Precision modifications can be made to standard bearings to save cost and delivery time on a brand-new design. Our bearing experts will guide you through the process to ensure the structural integrity of the bearing remains.
  • Learn more at Bearing Modifications.

Bearing Assemblies

  • Carter can provide precision matched components for bearing assemblies to offer a “plug-and-play” solution. We will get involved at the machine design phase to provide unparalleled bearing application technical support.

Bearing Materials

52100 Chrome Steel

Most common bearing material in the world. Martensitic chrome steel is a safe choice for standard applications.

MORE ABOUT THIS MATERIAL

440C Stainless Steel

The most common stainless steel bearing option. Martensitic stainless steel with reasonable corrosion resistance properties.

MORE ABOUT THIS MATERIAL

316 Stainless Steel

A great choice for low load and low speed applications that require extreme corrosion resistance. Austenitic stainless steel has many benefits.

MORE ABOUT THIS MATERIAL

M50 Tool Steel

High temperature and high speed steel common in main shaft engine bearings. This specialist steel could be the option for you.

MORE ABOUT THIS MATERIAL

BG42®

Extreme high temperature hardness and wear resistance. This steel is comes to the rescue when things heat up.

MORE ABOUT THIS MATERIAL

CRONIDUR® 30

Nitrogen enriched martensitic stainless steel with extraordinary corrosion resistance and fatigue strength.

MORE ABOUT THIS MATERIAL

Stellite 6B®

A “go to” for bearings in and around jet engines, high temperatures and corrosion don’t stand a chance.

MORE ABOUT THIS MATERIAL

Beryllium Copper

A non-ferrous alloy with extreme hardness, electrical and thermal conductivity and impact resistance. A unique choice for special applications.

MORE ABOUT THIS MATERIAL

Nylon/Polyamide

Machined or moulded, this is a low cost and light weight option suitable for standard applications.

MORE ABOUT THIS MATERIAL

PEEK

High temperature resistance and vacuum compatibile, this material excels in extreme environments.

MORE ABOUT THIS MATERIAL

PTFE

A widely used material due to low-cost and chemical resistance.

MORE ABOUT THIS MATERIAL

Phenolic

Very light weight material which is easily reinforced with complimentary fibres such as fabric or glass which makes it ideal for high speeds.

MORE ABOUT THIS MATERIAL

Brass

Precision machined components with high durability. Can run at higher temperatures at higher speeds.

MORE ABOUT THIS MATERIAL

Titanium

Titanium’s weight to strength ratio is second to none. This is a last resort cage material due to cost but could be necessary.

MORE ABOUT THIS MATERIAL

Full Complement

This arrangement has no physical cage and an increased ball compliment. This increases radial load capacity but drastically reduces axial.

MORE ABOUT THIS MATERIAL

Spacer Slugs, Toroids & Spacer Balls

Spacer balls are best used to reduce torque in low speed or oscilating applications.

MORE ABOUT THIS MATERIAL

XtrMD

Molybdenum Disulphide coatings reduce the coefficient of friction and increase speed capabilities.

MORE ABOUT THIS COATING

XtrTD

Tungsten Disulphide Coatings eliminate the need for liquid lubrication and are commonly used in Aerospace, space, ultra-high vacuum and clean room applications.

MORE ABOUT THIS COATING

XtrChrome

Thin Dense Chrome Coating increases wear and corrosion resistance of standard chrome steels to outperform stainless steel.

MORE ABOUT THIS COATING

XtrPoly

Polymer injected and cured lubrication acts as a complete shield while continuously lubrication the bearing.

MORE ABOUT THIS COATING

Standard Plating

A full range of standard plating is also available such as Cadmium and Zinc-Nickel.

Dry Lubricants

Specialist dry film lubrications can drastically improve bearing performance when chosen properly.

Aerospace Approved Lubrications

Flight critical Aerospace bearings require lubrication with particular temperature characteristics and chemical traceability. A full range of Aerospace Approved Oils and Greases are available.

Vacuum Compatible Lubrications

When used in deep space or in a ultra-high vacuum chamber, vacuum compatible lubrications are highly unique.

Low Torque Lubricants

Controlling the power input to run your mechanical system can be mission critical so low torque options are available.

Food Grade Greases

FDA approved food grade greases are readily available at Carter when requested.

Radiation-Resistance Greases

Nuclear applications call for non-reactive lubrications to minimize the radiation at time of service so they don’t stay “hot”.

Low Temperature Lubrication

Aerospace grade lubrication can be the best option to ensure low temperatures don’t impact bearing performance.

High Temperature Lubrication

A myriad of high temperature options are available at Carter from liquid lubrication to solid fill lubrication.

Waterproof Grease

When working in submersible environments, it’s important to specify a grease that will operate properly and not migrate in application.
