SKF NU252 MA

SKF NU 252 MA Cylindrical Roller Bearing Description The SKF NU 252 MA is a premium single row cylindrical roller bearing designed for applications that must support heavy radial loads and operate at high speeds. Its NU design means the inner ring has no flanges, allowing for axial displacement in either direction, which is ideal for accommodating thermal expansion of the shaft. This bearing is a non-locating bearing and must be used in conjunction with a locating bearing to provide axial shaft location.

FAQ Question?What does the ‘MA’ suffix signify in the SKF NU 252 MA?The ‘MA’ suffix indicates that the bearing is fitted with a machined brass cage which is centered on the outer ring. This type of cage provides high strength and is suitable for high speeds and demanding operating conditions. Question?Can this NU design bearing accommodate axial loads?No, the NU design is a non-locating bearing and is intended for radial loads only. It allows for free axial displacement of the shaft relative to the housing in both directions and cannot provide axial guidance. Question?What is the typical mounting procedure for a bearing of this size?For a large bearing like the NU 252 MA, mounting is typically done using heat (induction heaters) or oil injection methods to expand the inner ring for an interference fit on the shaft, preventing damage during installation.
