FAQ

What is the correct tightening torque for the set screws on the YAR 208-2F insert?

For a YAR 208-2F with an M8x1 set screw, SKF recommends a tightening torque of 6.5 Nm. Always use a calibrated torque wrench for proper installation.

Is this bearing unit pre-lubricated and ready for installation?

Yes, SKF bearing units like the FY 40 TR are supplied pre-filled with a high-quality grease. The grease nipple allows for re-lubrication as per the maintenance schedule of your application.

Can the bearing insert (YAR 208-2F) be replaced separately from the housing (FY 508 H)?

Absolutely. SKF bearing units are designed to be modular. You can purchase and replace just the YAR 208-2F insert if needed, which can be more cost-effective than replacing the entire unit.
