Design and Construction

The SKF 6207-2Z features a single row deep groove design, which allows it to accommodate radial loads and moderate axial loads in both directions. Its deep raceway grooves and close conformity between the balls and raceways enable smooth, quiet operation and high load-carrying capacity.

This bearing is equipped with metal shields on both sides (2Z), which provide effective protection against dust and other contaminants while retaining the lubricant inside. The shields are non-contact, ensuring minimal friction and allowing for high-speed operation without compromising performance.
