Cylindrical Roller Bearings SKF N217 ECP

The SKF N217 ECP cylindrical roller bearing is a single-row idler bearing measuring 85 × 150 × 28 mm, designed for high radial loads.

The N217 ECP cylindrical roller bearing belongs to the N series and, as a non-locating bearing, accommodates radial forces only. With a bore of 85 mm, an outside diameter of 150 mm and a width of 28 mm, this roller bearing is suitable for industrial shaft mountings. The open design allows for flexible lubrication via the surrounding housing. This SKF product is manufactured in the Explorer design and features an optimised internal construction as well as standard radial clearance.

What requirements does the N217 ECP cylindrical roller bearing meet?

Typical applications include industrial bearing arrangements where high radial forces are present and changes in shaft length must be accommodated. Due to its N design, the inner ring has two fixed flanges, whilst the flangeless outer ring can be removed from both sides. This allows the bearing to accommodate axial displacement of the shaft relative to the housing within the bearing. The permissible temperature range extends from –30 to +120 degrees Celsius, covering a wide variety of operating conditions in mechanical engineering.

What are the functions of the N design and the polyamide cage?

The polyamide cage guides the low-mass rollers and promotes smooth running during operation. When designing the bearing arrangement, it is important to note that the N design cannot transmit axial forces. You therefore always require a separate fixed bearing on the shaft. Furthermore, the detachable outer ring simplifies assembly, as you can press the inner and outer rings onto the shaft and housing separately. The running accuracy corresponds to tolerance class P6 or ABEC 3 with standard dimensional accuracy P0.
