Reliable rotation with Skf bearing

Practical benefits

Effective protection against debris: The dual metal shields keep lubricant securely inside while blocking external contaminants during operation.
Smooth and low-friction running: Thanks to the optimized raceway design, you achieve high rotational speeds with low noise and vibration.
Versatile bidirectional load capacity: This single row ball bearing accommodates both radial and axial forces across all directions reliably.

In a nutshell

The right choise for

With the Skf 6203-2Z deep groove ball bearing, you ensure smooth, low-friction rotation for electric motors, gearboxes, and industrial machinery. The dual metal shields keep factory lubricant securely inside while blocking dust and debris in dry working environments. Designed with a robust steel raceway, this single-row bearing reliably handles both radial and light axial loads at high rotational speeds with low vibration. Featuring dimensions of 17X40X12 mm, a cylindrical bore, and standard cn radial clearance, it offers an easy, direct fit for maintaining drive shafts, pumps, and conveyor systems.

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
