Roller Bearing Units
New SKF ConCentra SYAF roller bearing units introduce ready-to-mount and highly reliable solutions for conveyors exposed to harsh operating conditions. The “shaft ready” one-piece assembled units integrate pre-lubricated SKF Explorer spherical roller bearings offering high load-carrying capacity, long life, and high-quality performance.
The bearing units mount and dismount to the shaft quickly from the same side using only a torque wrench reducing axial space requirements. Once the bearing unit is correctly positioned on the shaft, angled set screws are tightened to axially displace the precision-engineered and matched stepped inner ring and sleeve, compressing the inner sleeve to grip the shaft evenly around the entire shaft circumference for a true concentric, tight fit. Up to 1.5 degrees of shaft misalignment can be accommodated without diminishing seal effectiveness. Shaft diameters range from 3 7/16 in. to 4 15/16 in. and the units can accept commercial grade or re-usable shafting without necessitating specially machined and costly ground or polished shafts. Housings are interchangeable to industry bolt-pattern standards.
