Cylindrical Roller Bearings SKF N316 ECP

The SKF N316 ECP cylindrical roller bearing is an open, single-row idler bearing with main dimensions of 80 x 170 x 39 mm and a polyamide cage.

As a single-row cylindrical roller bearing, the N316 ECP withstands high radial loads and supports shafts in industrial bearing arrangements. With an inner diameter of 80 mm, an outer diameter of 170 mm and a width of 39 mm, this design fits into standardised housing bores. As an open bearing, the component can be integrated directly into an existing lubrication system. SKF’s Explorer design features an optimised internal construction that reduces friction and promotes smooth running of the cylindrical rollers.

What is the N316 ECP cylindrical roller bearing suitable for in operation?

This bearing is primarily designed to accommodate high radial loads at medium to high speeds. Typical applications include general mechanical engineering and heavy-duty industrial applications with purely radial loads. As the outer ring is designed to be removable on both sides, the assembly functions as a conventional non-locating bearing. The system effortlessly compensates for thermal length changes in the shaft directly within the bearing. At the same time, the separable design facilitates the sequential mounting of the inner and outer rings onto the shaft and housing.

What are the advantages of combining the free-running bearing design with a polyamide cage?

The integrated polyamide cage is characterised by its low weight, which reduces inertial forces during rapid speed changes. The permissible operating temperature range is from –30 to +120 degrees. Dimensional accuracy complies with tolerance class P0 (ABEC 1), whilst running accuracy is manufactured to P6 (ABEC 3). As the bearing has no integrated seals, surrounding machine parts must provide protection against contamination. Ensure that the lubricant is supplied in a clean manner.

What operating principle characterises the design of the N316 ECP cylindrical roller bearing?

In the N design, the bearing has fixed flanges on the inner ring, whilst the outer ring remains flangeless and can be removed from both sides. As a result, the unit acts purely as a non-locating bearing that does not absorb any axial forces. The design compensates axially for changes in shaft length caused by temperature differences without any internal clamping.

What are the dimensions of the N316 ECP cylindrical roller bearing?

This version has a bore of 80 mm, an external diameter of 170 mm and a width of 39 mm. These dimensions comply with the standardised series. Before installation, check the shaft seat and the housing bore to ensure that the rings fit precisely.

What is the permissible temperature range for the N316 ECP cylindrical roller bearing?

The permissible operating range is between -30 and +120 degrees. These limits take into account the behaviour of the rolling elements, rings and the polyamide cage. To ensure smooth running, it is necessary to select a lubricant whose viscosity is suited to this temperature range and the actual operating temperature.

What does tolerance class P6 mean in terms of running accuracy?

The P6 precision class (corresponding to ABEC 3) defines tighter concentricity tolerances than the standard P0 class. The dimensional accuracy of the mounting dimensions remains at P0 (ABEC 1). This combination ensures smooth, low-vibration operation of the cylindrical rollers at high speeds, whilst still allowing installation on standard mounting surfaces.

Why does the open cylindrical roller bearing require an external seal?

The model does not come with integrated sealing washers as standard. An open roller bearing allows for direct lubrication via an oil circuit or by filling the bearing housing with grease. To prevent the ingress of dirt particles or moisture, external sealing elements such as shaft seals or labyrinth seals must be incorporated into the housing design.

What is the function of the polyamide cage in the bearing?

The cage keeps the cylindrical rolling elements at a uniform distance apart and prevents them from coming into contact with one another. Thanks to the elastic and damping properties of the polyamide, the bearing runs quietly. Furthermore, the low weight of the plastic reduces the inertial forces during acceleration of the shaft supported by the bearing.
