22309 HE4C4U15-VS VIBRATING SCREEN SPHERICAL ROLLER BEARING

 Rolling bearings in vibrating screens are stressed by high, mostly shock-type loads. Moreover, the bearings, while rotating about their own axis, peform a circular, elliptical or linear vibrating motion. This results in high radial accelerations which additionally stress the bearings, and especially the cages, considerably.

• Precision machined tough one piece brass cage, contoured roller pockets.

• Improved surface roughness on rollers & inner & outer ring.

• Special heat treatment rollers, prevent cracks from vibrations & shock loads.

• Self aligning ability with floating guide ring.

• Controlled roller skew.

• Internal radial clearance set at 2/3 ISO standard bearings.

• Outer dimensions set at 1/2 of ISO standard bearings

• 40mm - 200mm bore diameter.

PRODUCT BENEFITS

• Twice the service life of conventional bearings

• Reduced maintenance costs.

• High dynamic & static load ratings - load rating increased by 1.25 times.

• Dampened vibration & highly resistant to heavy or shock loads.

• High speed performance & low operating temperature rise.

• Better roller guidance & smooth running - reduced bearing damage from slippage, surface fatigue, flaking.
