What are the dimensions of this bearing?

The bearing has an inside diameter of 8 mm, an outside diameter of 22 mm, and a width of 7 mm.

What is the main advantage of a self-aligning ball bearing?

It compensates for angular misalignment and shaft deflections without causing extra friction.

What does the TN9 suffix indicate?

The TN9 code indicates a cage made of glass-fibre reinforced polyamide (plastic material).

Is this ball bearing sealed?

No, this is an open-type bearing without integrated seals.

What type of bore and clearance does this model have?

The bearing has a cylindrical bore and normal internal radial clearance (CN).

Smooth alignment with Skf

Practical benefits

Automatic misalignment compensation: You easily accommodate shaft deflection and angular errors thanks to the dual-row design with a spherical outer raceway.
Low friction high speeds: The lightweight polyamide cage minimizes heat build-up and running noise, ensuring you maintain smooth rotational efficiency.
Compact cylindrical mounting: With standard dimensions of 8X22X7 mm, you fit this bearing directly onto straight shafts without hassle.

In a nutshell

The right choise for

With the Skf 108 TN9, you ensure smooth and reliable rotation in your machinery and precision instruments. This double-row self-aligning ball bearing effortlessly accommodates shaft deflections and angular misalignments, preventing premature bearing wear. The lightweight glass-fibre reinforced polyamide cage minimizes friction and heat build-up, allowing smooth, quiet operation at high speeds. Featuring a cylindrical bore and compact dimensions of 8X22X7 mm, you install this open bearing directly and accurately onto an 8 mm shaft.
