Cylindrical Roller Bearings SKF NUP2216 ECP
The SKF NUP2216 ECP cylindrical roller bearing is a single-row fixed bearing with an 80 mm bore, a 140 mm outer diameter and a flexible polyamide cage.
As an open roller bearing, the NUP2216 ECP cylindrical roller bearing accommodates high radial loads and supports shafts axially in both directions. With dimensions of 80x140x33 mm, this SKF bearing is suitable for demanding industrial applications. The Explorer design features an optimised internal construction. Single-row roller bearings can transmit higher radial loads than ball bearings of a comparable size, as the cylindrical rollers have a line-contact surface.
What is the NUP2216 ECP cylindrical roller bearing suitable for?
This fixed bearing is used where heavy radial loads occur and the shaft must simultaneously be fixed in both axial directions. Thanks to the combination of fixed flanges on the outer ring and a fixed flange with a loose flange disc on the inner ring, the bearing performs axial guidance functions. Typical applications include shaft mountings in general mechanical engineering and gearbox construction where combined loads are present. An external lubricant supply is required for operation.
What is the function of the NUP design and the polyamide cage?
The NUP design enables the shaft to be axially secured on both sides within the housing, thereby eliminating the need for additional axial bearings. The integrated polyamide cage (suffix ECP) reduces the weight of the rotating components and promotes quiet, low-friction operation. The bearing is designed for a temperature range of -30 to +120 degrees. With standard radial clearance and high running accuracy of class P6, it fits precisely into matched machine seats.
What are the key features of the NUP2216 ECP cylindrical roller bearing?
As a single-row cylindrical roller bearing in a fixed-mount design, the bearing has a bore diameter of 80 mm, an outer diameter of 140 mm and a width of 33 mm. It has two fixed flanges on the outer ring and one fixed flange and one loose flange disc on the inner ring. A lightweight polyamide cage guides the rolling elements with minimal vibration.
What loads can the NUP design withstand?
This design is primarily intended to absorb high radial forces. Thanks to the combination of solid flanges on the outer ring and the flange disc on the inner ring, the bearing also provides additional axial support for the shaft in both directions. As a result, the design functions as a compact fixed bearing within the bearing assembly.
What does the suffix ‘ECP’ mean at SKF?
The designation ‘ECP’ refers to an optimised internal design (E) and a polyamide cage (CP). This cage material absorbs shocks elastically, reduces friction losses and is suitable for operating temperatures between -30 and +120 degrees.
What are the bearing’s tolerance classes?
The dimensional accuracy complies with standard class P0 (equivalent to ABEC 1), whilst the running accuracy is to class P6 (equivalent to ABEC 3). This classification ensures uniform concentricity with a precise fit between the shaft and the housing.
How is the open cylindrical roller bearing lubricated?
In the case of open roller bearings without integrated sealing washers and without a lubrication groove on the outer ring, the lubricant is supplied via the surrounding structure. Depending on the design, the bearing can be operated with lubricating oil or a suitable bearing grease and requires an external housing seal.
