FAQ

What is the difference between this H 310/40 D and a standard H 309 sleeve?

A standard H 309 sleeve is designed for a 40mm shaft. This akn H 310/40 D uses the larger outer dimensions and thread of an H 310 series sleeve (which is standard for a 45mm shaft) but is manufactured with a 40mm bore. This makes it a special variant, potentially for applications requiring a more robust sleeve body or a specific housing fit.

What is the correct procedure for tightening the KM 10 lock nut?

The KM 10 lock nut should be tightened to remove the internal clearance of the bearing until a firm seating is achieved. Use a hook or impact spanner. Once properly tightened, one of the tabs on the MB 10 lock washer should be bent into a corresponding slot on the circumference of the lock nut to prevent it from loosening during operation.

Is this sleeve suitable for high-speed applications?

Yes, the ‘HSP’ marking on the sleeve likely stands for High Speed Precision. The precise manufacturing tolerances of this sleeve assembly make it suitable for applications with higher rotational speeds, ensuring minimal vibration and run-out.
