features

• Shaft ready: prelubricated with standard grease for normal operation
• other lubricants available for special conditions
• Fully self-aligning: spherical roller bearing to accommodate operational and installation misalignment
• Integral self-alignment: Rex® Roller Bearings represent the continuation of 80 years of bearing technology and experience built upon the original Shafer design, consisting of: an inner race which forms a segment of a sphere
• rollers shaped concave
• Design allows the inner race to misalign freely in any direction up to 1 1/2° from center, 5/16" per foot of shaft length
• Rollers are aligned by the retainers and the outer races, so despite misalignment the roller load is always equally distributed: this prevents high edge load stresses on the rollers, which in turn means that it is not necessary to derate Rex Bearings f
• By design, Rex Bearings accept both radial and thrust loads under static, oscillatory, or dynamic conditions: load is taken on the roller raceways, not the roller ends, meaning that when thrust loaded up to their allowable limit, Rex Bearings do not ex
