Roller Bearings

A rolling bearing, also called a rolling-element bearing, is a bearing that bears a heavy load by putting rolling elements between two grooved, concentric rings known as races. The relative motion of the races enables the sliding and rolling resistance of the rolling parts to be relatively low. One of the earliest and most well-known rolling-element bearings is a unit of logs put on the ground containing a big stone block on top of it. As the stone is drawn, the logs roll on the ground, creating small amounts of sliding friction.

What is the Function of a Roller Bearing?

Bearings, which are engineered to support a load while reducing friction, are often referred to as rolling-element bearings. Instead of employing balls to keep the bearing's moving sections apart, bearings transmit loads using cylinder-shaped rolling elements.

Popular Types of Rolling Bearings

While there are several variations and specialised rolling bearings for very specific industrial applications, we will here discuss the four most significant types.

  • Ball Bearings: The most popular choice, ball bearings, is available in a wide range of shapes and may be utilised in a variety of applications. The industrial application for which it will be used and the load it will be subjected to will determine the type of ball bearing to be used.
  • Needle Roller Bearings: In their construction, they have cylindrical, thin, long rollers in their diametral plane. They are the best solution when the transmission demands a high radial load capacity and are particularly well suited to applications with constrained space (the axial dimension of the needles or rollers is substantially bigger than the radial one).
  • Roller Bearings: These parts have a ring with cylindrical rollers and a line of cylindrical rollers enclosed between solid exterior and internal rings. The cage stops the cylindrical rollers from rubbing against one another as they roll, reducing friction and enduring high speeds and sudden accelerations.
  • Thrust Roller Bearings: They are made to support and react exclusively to axial stresses, as their name suggests. Radial loads should not be used with them. There are two categories: single direction kinds (axial load in a single direction) and ( axial load in both directions).

Metric Single-row taper roller bearings can only take axial loads in one direction. The forces generated in the bearing by radial loads, and the force acting axially, must be offset by an external counter force. This is why in practice single-row taper bearings are mounted against a second taper roller bearing. Dimensions comply with data in DIN ISO 355 and DIN 720, 1979

NJ 2311 ECP/C3, SKF

Single row cylindrical roller bearings SKF single row cylindrical roller bearings are available in many designs, series and sizes. Features: C3 Clearance on this model. High load carrying capacity High stiffness Accommodate axial displacement Except for bearings with flanges on both the inner and outer rings. Low friction The open flange design, together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction and higher axial load carrying capability. Long service life The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection. Enhanced operational reliability The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film. Separable and interchangeable The separable components of SKF cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections.
