Dependable performance with Skf bearings

Practical benefits

Double shielded dirt protection: Metal shields on both sides retain factory grease and block debris, keeping your mechanical drives running smoothly with minimal maintenance.
Accommodates high rotational speeds: Built with internal C3 clearance, this bearing absorbs thermal expansion effortlessly when you operate machinery at elevated operating speeds.
Durable polyurea grease filling: Premium factory lubrication maintains film stability under varying temperatures, ensuring you prevent premature wear across intensive industrial applications.

In a nutshell

The right choise for

Keep your electric motors and continuous drive systems running reliably with the Skf 6203-2Z/C3GJN deep groove ball bearing. Designed with increased C3 internal clearance, it easily handles thermal expansion to prevent binding during high-speed, elevated-temperature operations. Dual 2Z metal shields keep harmful dust out while retaining the factory-filled polyurea grease, eliminating the need for periodic relubrication and saving valuable maintenance time. Engineered for a straight 17 mm shaft with its cylindrical bore, this single-row steel bearing efficiently accommodates both radial and axial loads in either direction.

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.
