What Types of Bearings Does Bearing King Supply?

Different types of bearings are designed for different combinations of load, speed, movement, alignment and operating conditions. Choosing the correct bearing is therefore important for reliable performance and service life.

Bearing King's range includes ball bearings, roller bearings, thrust bearings, housed bearings, bushes, specialist bearings and bearing accessories.

Ball Bearings

Ball bearings are among the most widely used bearing designs. They use rolling balls between the inner and outer bearing rings to reduce friction and allow smooth rotational movement.

Our ball bearing range includes:

• Deep Groove Ball Bearings – A widely used bearing type for electric motors, pumps, gearboxes, conveyors and general machinery. Deep groove designs can accommodate radial loads and axial loads in both directions.
• Angular Contact Ball Bearings – Designed for applications where radial and axial loads act simultaneously. They are commonly used in machine tools, pumps, compressors and precision engineering equipment.
• Self-Aligning Ball Bearings – Designed to accommodate a degree of shaft or housing misalignment, making them useful where perfect alignment cannot always be maintained.
• Super Precision Bearings – Precision bearing products intended for applications requiring high accuracy, controlled movement and low vibration.

If you are comparing different ball bearings, check the bearing reference, dimensions, sealing arrangement, clearance and application requirements before selecting a replacement.

Roller Bearings

Roller bearings use cylindrical, tapered, spherical or needle-shaped rolling elements instead of balls. They are commonly selected for applications involving heavier loads or particular alignment and space requirements.

Our roller bearing range includes:

• Cylindrical Roller Bearings – Designed to support high radial loads and widely used in electric motors, gearboxes, machine tools and industrial machinery.
• Needle Roller Bearings – Compact roller bearings that provide high load capacity relative to their cross-section. They are often found in automotive, agricultural, motorcycle and power-tool applications.
• Taper Roller Bearings – Designed to accommodate combined radial and axial loads. Common applications include wheel hubs, trailers, gearboxes and agricultural machinery.
• Spherical Roller Bearings – Heavy-duty bearings designed to accommodate substantial loads while tolerating shaft misalignment. They are frequently used in conveyors and demanding industrial machinery.
• Thrust Bearings – Bearings specifically designed for applications where axial or thrust loads are a primary consideration.

Bearing Units, Bushes & Accessories

A complete bearing installation may require more than the bearing itself. Bearing King also supplies housings, inserts, bushes, sleeves and associated components for installation, replacement and maintenance.

Our range includes:

• Housed Bearings & Inserts – Complete bearing arrangements designed to simplify mounting in conveyors, agricultural machinery and production equipment.
• Oilite & Wrapped Bearing Bushes – Bearing bushes for applications requiring compact, reliable sliding support.
• Sleeves, Lock Nuts & Washers – Components used in the mounting and securing of compatible bearings.
• Loose Balls – Precision bearing balls for repairs, bicycles, engineering projects and specialist applications.

Specialist Bearings

Bearing King also stocks specialist bearings for applications that fall outside conventional ball and roller bearing requirements.

These include:

• Cam Followers – Designed to follow tracks and cams in machinery, automation and material-handling systems.
• Track Rollers – Roller components for tracks, guide systems and material-handling equipment.
• Rod End Bearings – Used in mechanical linkages and applications requiring angular movement.
• Sprag Clutch Bearings – One-way bearing arrangements used where rotation or torque must be transmitted in one direction.
• Trailer Bearings – Replacement bearings for trailer and towing applications.
• Skateboard Bearings – Bearings for skateboards, scooters, inline skates and related applications.
• Lazy Susan Turntable Bearings – Turntable bearings designed to provide smooth rotational movement for tables, displays and other rotating platforms.
• Linear Ball Bushings & Linear Bearing Units – Components designed for controlled linear rather than rotational movement.
• Go Kart Bearings – Bearings and related components for go-kart applications.

How Do I Choose the Correct Bearing Size?

Finding the correct bearing size is one of the most important steps when replacing an existing bearing.

If the original bearing reference is still visible, this is usually the best starting point. Enter the reference into the Bearing King website search to locate matching products.

If the number has worn away or cannot be identified, compare the main bearing sizes by taking three measurements:

• Inside Diameter (ID) – The diameter of the bore or centre hole.
• Outside Diameter (OD) – The overall external diameter of the bearing.
• Width – The thickness of the bearing from one side to the other.

These measurements can help narrow down potential replacements.

Bearing King stocks both metric and imperial bearings, providing replacement options for British, European, American, Japanese and other machinery.

If two bearings have similar dimensions, do not assume they are automatically interchangeable. The bearing type, seals or shields, internal clearance and application requirements may also need to be considered.

If you are uncertain, contact our team with the bearing number, dimensions or equipment information and we can help identify a suitable replacement.

Metric & Imperial Bearing Sizes

Our range includes a wide selection of metric and imperial bearing sizes for modern and older machinery.

Metric bearings are common across industrial, automotive and engineering equipment, while imperial bearings remain important for many British and American machines, specialist equipment and older installations.

When searching by dimension, record the inside diameter, outside diameter and width as accurately as possible. These measurements can then be compared against available bearing specifications to help identify the correct product.

Shop Bearings by Brand

Bearing King stocks genuine bearings from established manufacturers covering industrial, automotive, engineering, agricultural and cycling applications.

Our leading bearing brands include:

• SKF – Bearings for a wide range of industrial and engineering applications.

How Do I Identify a Replacement Bearing?

Start by looking for a reference number printed, stamped or engraved on the existing bearing.

If the reference can be read, search that number directly on the Bearing King website.

If there is no visible number:

1. Measure the inside diameter.
2. Measure the outside diameter.
3. Measure the bearing width.
4. Note whether the bearing has seals, shields or an open design.
5. Record any markings that remain visible.

These details can make it much easier to identify potential replacement bearings.

If you still cannot find a match, contact our technical team with the measurements, photographs or application information and we can help narrow down the available options.
