Supplying BearingsProviding Support
Bearings are mechanical components used to reduce friction between moving parts and support loads. They allow for smooth rotation or linear movement in machinery and various applications.
We are distributors for many industry leading bearing manufactures and our vastly experienced technical team are always available to help with any questions or concerns you may have. If you require assistance identifying the right bearings for your requirements we can offer help from our trade counter, over the phone or at your site.
Identifying a bearing involves determining several key dimensions.
Inner Diameter (ID): This is the diameter of the hole in the center of the bearing where it fits onto the shaft. Use a caliper or an internal gauge for accurate measurement.
Outer Diameter (OD): This is the overall diameter of the bearing. Again, a caliper is ideal for this measurement.
Width (or Thickness): Measure the width of the bearing, which is the distance between the inner and outer rings. Use a caliper to get an accurate reading.
Bearing Type and Series: Identify the type (e.g., ball bearing, roller bearing) and series number, which can usually be found on the bearing’s outer ring.
Other Features: Any additional features, like grooves, seals, or shields, will affect compatibility.
Ball Bearings: These bearings use balls to reduce friction. They are versatile and commonly found in various machinery, including electric motors and bicycles.
Roller Bearings: Instead of balls, these bearings use cylindrical rollers. They can handle higher loads and are often used in heavy machinery and conveyor systems.
Tapered Roller Bearings: These bearings have tapered inner and outer races, allowing them to handle both radial and axial loads. They are commonly used in automotive applications, such as wheel hubs.
Spherical Bearings: Designed to accommodate misalignment, these bearings consist of an inner spherical surface and an outer spherical surface. They are often used in linkages and suspensions.
Needle Bearings: A type of roller bearing with long, thin rollers. They are useful in applications where space is limited and are commonly found in automotive engines.
Thrust Bearings: These bearings are designed to handle axial loads. They come in various forms, including ball and roller types, and are often used in applications like gearboxes.
Each type has unique characteristics suited for specific applications, so the choice of bearing depends on factors like load, speed, and environmental conditions.
