Roller Bearings

		Home \| English \| Français



	Roller Bearings Roller bearings are more diverse than ball bearings and their rolling elements can be of differing shapes and can carry greater loads than ball bearings. For example, cylindrical roller bearings will accommodate heavy radial loads, whereas sphericals will carry heavy radial loads combined with moderate thrust loads.

SPHERICAL ROLLER BEARINGS
Spherical roller bearings have two rows of rollers which run on a common sphered raceway in the outer ring. They are used when heavy axial and radial loads are present and accurate alignment can not be guaranteed.

SPHERICAL ROLLER BEARINGS

FOR VIBRATING EQUIPMENT

NSK's vibrating equipment bearings are engineered specifically to withstand the high speed, shock loading, misalignment, and marginal lubrication conditions typical of the vibratory equipment in the Aggregates, Mining & Construction Industries.

FEATURES

• High capacity design
• One-piece machined brass
cage
• Guide ring
• Symmetrical rollers with
contoured surfaces
• Special outside diameter
tolerances and radial clearance
• Increased shock load
protection

BENEFITS

• Increased fatigue life
• A robust cage for heavy duty
operations prevents cage fracture
• The ring guides the rollers to reduce
wear and lowers internal temperature
• The symmetrical rollers increase
limiting speed by reducing stress and
temperature on the rollers and
raceways
• More reliable fits and reduced risk of
seizure
