Smooth rotation with Skf

Practical benefits

Thermal expansion clearance C3: The internal C3 clearance ensures you maintain smooth rotation even when operating temperatures and speeds increase.
Double metal dust shielding: Two metal shields keep lubricating grease inside while protecting your internal rolling elements against external debris.
Versatile combined load handling: You easily support both radial and axial loads in compact drives, pumps, and rotating equipment.

In a nutshell

The right choise for

Keep your rotating equipment running smoothly and reliably with the Skf 6004-2Z/C3 single row deep groove ball bearing. Engineered with a 20 mm cylindrical bore, a 42 mm outer diameter, and a 12 mm width, this steel bearing effortlessly supports both radial and axial loads in both directions. The C3 radial internal clearance ensures consistent performance even when operating temperatures and rotational speeds rise. Featuring dual metal shields (2Z), it effectively keeps out dust and contaminants while retaining essential lubricant inside the rolling elements. It provides dependable protection against downtime in electric motors, pumps, gearboxes, and compact industrial machinery.

Product description

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.

Integral sealing prolongs bearing service life
Simple, versatile and robust design
Low friction and high-speed capability
Accommodate radial and axial loads in both directions
Require little maintenance
