CYLINDRICAL ROLLER BEARINGS 72XX

Type: Angular contact cylindrical roller bearings (series 72). A single row of rollers with a contact angle designed to absorb radial and axial loads simultaneously.

Features: Crowned or tapered cylindrical rollers to reduce stress concentration, inner ring with inclined raceway, outer ring with an equally inclined raceway.

Load capacity: High radial capacity, moderate bidirectional axial capacity thanks to the contact angle. Suitable for balanced combined loads.

Speed: Medium to high speeds (up to 14,000 rpm), low friction thanks to the crowned roller profile, reduced heat generation.

Protection: Available open without protection, with shields, or sealed. Basic design for applications with constant oil lubrication.

Lubrication: Oil lubrication is generally preferred for effective cooling and friction reduction. They require scheduled maintenance.

Specifications: High radial capacity, bidirectional axial capacity, low friction, medium to high speeds, temperatures -30°C to +80°C.

Applications: Machine tools, spindles, automotive transmissions, rotating systems where combined radial-axial loads are present.

Benefits: Combined load, high speeds, low friction, precise and robust for mechanical applications.
