ROLLER BEARINGS

Bearings Direct supplies a large variety of roller bearings and needle roller bearings.

Roller bearings are any cylindrical or spherical object that aids in the movement of an object greater in size than the bearing itself. They are weight distribution-oriented bearings; this means they utilize many points of contact between a circular housing that contains the internal rolling elements, such as ball bearings, that sit within a collar. These bearing systems use the decrease in rolling resistance as a means of increasing the efficiency of moving an object.

Roller bearings typically fall within three categories: cylindrical, tapered, and needle.

Types of Roller Bearings

Bearings Direct is a large roller bearings supplier with a selection of various sizes and shapes. Some of the types of roller bearings we supply include:

Cylindrical: Bearings in which cylinders are used as the rolling elements. With a greater contact area, they can distribute loads across a larger surface leading to a high radial load capacity. Bearings Direct supplies fully removable and one-side removable single row cylindrical bearings. These are best used for light to medium duty applications.

Tapered: Bearings that can support axial and radial forces. Due to a conical geometry that creates a linear contact, these bearings can carry greater loads than ball bearings, which have point contact. Tapered roller bearings can be separated into a cone assembly (inner ring, rollers, cage) and a cup (outer ring). These bearings can be used in industries such as agriculture, construction, mining, automotive, and robotics.

Needle: Bearings similar to cylindrical roller bearings except that they utilize small cylindrical rollers with lengths 3 to 10 times their diameter. These bearings have a high radial load capacity and are best suited for applications in which radial space is minimal.

Drawn Shell Cup Needle Roller Bearings: Bearings which have a high length-to-diameter ratio that may be lubricated with grease or oil-based lubricants. Commonly used in applications such as agriculture equipment, engines, and small appliances. Bearings Direct supplies both metric and inch size is drawn shell cup needle rollers.

Spherical Roller Bearings: Bearings that allow rotation with low friction and angular misalignment. These bearings consist of cylindrical rolling elements and usually support a rotating shaft in the inner ring which may be misaligned with the outer ring. These bearings can handle heavy radial and axial loads and are used in applications where misalignment is a challenge.
