CYLINDRICAL ROLLER BEARINGS 73XX

High contact angle: Larger contact angle (approximately 25-30°) allows very high bidirectional axial capacity, with less compromise on radial capacity.

Features: Crowned rollers to distribute the load evenly, inclined raceways on both rings, pressed steel or polyamide cage.

Load capacity: High radial capacity retained, very high bidirectional axial capacity thanks to the increased angle.

Speed: Medium speeds (up to 12,000 rpm), low friction thanks to the crowned profile, suitable for sustained rotation with combined loads.

Protection: Available open without protection, with shields, or sealed according to application requirements.

Lubrication: Oil lubrication preferred for effective cooling and friction reduction. Scheduled maintenance is essential.

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

Applications: Machine tools with high axial load, loaded spindles, heavy automotive transmissions, systems with significant axial thrust.

Benefits: Maximum bidirectional axial load, good radial capacity, low friction, precise for critical applications.
