6 Popular Types of Kaydon Bearings and Their Uses

Kaydon Bearings are known for their high quality and versatility, making them a preferred choice across various industries. This blog will explore six popular types of Kaydon bearings, including Kaydon slewing bearings and Kaydon thin section bearings. Understanding these bearings will help you select the right one for your needs, ensuring optimal performance and reliability in your machinery.

Kaydon Slewing Bearings

Kaydon slewing ring bearings, also known as slewing rings, are designed to handle axial, radial, and moment loads simultaneously. They are robust and reliable, making them suitable for heavy-duty applications. 

These include four point contact slewing ring bearings, eight point contact slewing ring bearings, cross roller slewing ring bearings, etc.

Here are some series of Kaydon Slewing Bearings.

HT Series Slewing Ring Bearings

HT Series slewing ring bearings feature increased ball diameter and cross-sectional area for greater capacity. They use deep groove gothic arch raceways and maximum ball complement, resulting in a four-point contact design that handles significant moment, thrust, and radial loads.

Features

• High axial, radial, and moment load capacity
• Suitable for heavy-duty machinery and equipment
• Available in various sizes and configurations

Applications

• Cranes and excavators
• Wind turbines
• Chute swivels
• Lift truck rotators
• Aerial lifts
• Digger derricks
• Industrial turntables

MT Series Slewing Ring Bearings

MT Series slewing ring bearings are compact and versatile, ideal for medium-load applications where space is a constraint.

These bearings share the four-point contact design of heavier duty models, providing excellent moment, thrust, and radial load capacity. They are a cost-effective replacement for kingpost designs.

Features

• Moderate axial and radial load capacity
• Compact design for space-saving solutions
• Precision manufacturing for smooth operation

Applications

• Robotics
• Medical equipment
• Non-precision industrial tables
• Positioners
• Small cranes and hoists
• Truck mounted cranes

KH Series Slewing Ring Bearings

KH Series slewing rings are designed for precise positioning with consistent repeatability. They are ideal for applications where rotation is constant, intermittent, or oscillating. These bearings are perfect for advanced rotary index tables and other precision mechanical components.

Features

• High precision and low friction
• Durable materials for extended service life
• Optimized for minimal maintenance

Applications

• Rotary index tables
• Precision instrumentation
• Aerospace
• Defense systems

RK Series Slewing Ring Bearings

RK Series slewing bearings are pre-engineered with a light profile, offering high performance and reduced weight. Their optimized geometry handles a combination of moment and thrust loads, making them suitable for applications with intermittent rotation and low velocity.

Applications

• Foundry shakeout tables
• Palletizers
• Wire winders
• Cable reels
• Welding tables

Kaydon Thin Section Bearings

Kaydon thin bearing solutions offer significant benefits, including weight savings, space optimization, reduced friction, increased design flexibility, and superior running accuracy.

Kaydon bearings come in an extensive range of materials, separator options, cross sections, internal fit choices, lubricants, corrosion-resistant options, contact angles, and precision levels. This variety ensures that you can find the perfect bearing to meet your specific needs.

Here are two popular types of Kaydon Thin Section Bearings:

Reali-Slim® Thin Section Bearings

Reali-Slim® thin section bearings are a lightweight and compact solution for applications where space is limited. They are available in three different bearing types:

• Radial Contact Ball Bearings (Type C)

• Angular Contact Ball Bearings (Type A)

• Four-Point Contact Ball Bearings (Type X)

These bearings includes both open and sealed bearings, along with various other variants. These bearings can be customized to accommodate various load types and are available in three different arrangements for angular contact ball bearings:

• Tandem arrangement
• Back-to-back arrangement
• Face-to-face arrangement

These designs provide multiple options to meet load, stiffness, and accuracy requirements efficiently. In many applications, a single Reali-Slim four-point contact ball bearing can replace two bearings, simplifying the design and saving space, weight, and cost.

Applications

Reali-Slim® thin section bearings are ideal for industries and applications requiring precise positioning and lightweight designs, such as:

• Food processing
• Aerospace
• Machine tools
• Robotics
• Tube and pipe cutting machines
• Medical Equipment
• Semiconductor manufacturing

Reali-Slim TT® Turntable Bearings

Reali-Slim TT turntable bearings are designed to handle radial, axial, and moment loads simultaneously, making them ideal for space-constrained applications. These bearings are based on a sealed four-point contact ball bearing and come in three different designs:

• Bearings without a gear

• Bearings with an external (outer ring) gear

• Bearings with an internal (inner ring) gear

Design Features

• Four-Point Contact Design: Provides high load-carrying capacity and stability.
• Material: Inner rings, outer rings, and balls are made from AISI 440C stainless steel for corrosion resistance and durability.
• Ball Size: Contains 1/8-inch balls for smooth operation.
• Cage Design: Fitted with a snap-type, stamped brass cage, ensuring proper spacing and smooth movement.
• Seals: Equipped with sheet steel reinforced NBR contact seals on both sides to protect against contaminants.
• Lubrication: Factory-lubricated with general-purpose grease for maintenance-free operation.
• Mounting: Inner and outer rings have through holes sized for #4 fasteners, simplifying installation.

Advantages

• Space and Weight Efficiency: A single Reali-Slim TT bearing can often replace two bearings, saving space, weight, and cost.
• Preload Options: Bearings can be furnished with internal radial preload for greater stiffness or zero clearance, achieved by using larger balls that create elastic deformation in the ring raceways.
• Gear Options: Bearings with internal or external gears feature a 64 diametral pitch and a 20° pressure angle for low backlash. Bearings without gears have mounting piloting diameters controlled to 0.0008 in (0.02 mm).
• Customization: Available with various drive options, including gearing/timing belts, and optional clearances or preload to meet specific torque or deflection requirements.
• Attachment Hole Types: Options include threaded holes (sized for #4-40 UNC fasteners) and countersunk holes (sized for #4 fasteners) for flexible mounting solutions.

Applications

These Kaydon bearings are engineered for demanding applications with stringent specifications, including:

• Radar antennae
• Robotics
• Factory positioning and inspection tables
