Cylindrical Roller Bearings SKF NU217 ECP

The SKF NU217 ECP cylindrical roller bearing, a free end bearing with dimensions of 85x150x28 mm, offers a high radial load capacity in a compact design.

The SKF NU217 ECP cylindrical roller bearing is a single-row radial roller bearing with a cylindrical bore for industrial applications. With dimensions of 85 mm inside diameter, 150 mm outside diameter and 28 mm width, the bearing can withstand high radial forces. The Explorer bearing version features an optimised internal design. A polyamide cage guides the rolling elements with low friction. As an open bearing, this version can be flexibly integrated into the plant’s lubrication systems.

What functions does the NU217 ECP cylindrical roller bearing perform as a non-locating bearing?

Designed as a floating bearing, this design accommodates purely radial loads and compensates for axial length changes of the shaft within the bearing. As the inner ring has no flanges and can be removed from both sides, the inner and outer rings can be fitted separately. Typical applications include bearing arrangements where operational thermal expansion of the shaft must be compensated for. The permissible operating temperature ranges from -30 to +120 degrees.

What is the function of the polyamide cage in the ECP variant?

The suffix ECP refers to the optimised internal geometry in combination with a lightweight polyamide cage. This cage keeps the cylindrical rollers spaced apart and reduces the moving mass within the bearing. In addition to the standard radial clearance, this model offers dimensional accuracy to tolerance class P0 or ABEC 1, as well as increased running accuracy to P6 or ABEC 3. This supports smooth rotational movement on precisely machined shaft seats.
