Product identity

The SKF 11340 is a rotary shaft seal built to the CRW1 design code with a 1.125 in inside diameter, a 2 in outside diameter and a 0.25 in overall width. It is intended for technicians and maintenance teams who need a reliable lip seal for rotating equipment.

Build integration

The seal fits directly into a 2 in bore and runs on a 1.125 in shaft, using a single nitrile rubber lip held by a carbon steel spring. Its acrylic case coating eases installation and the design tolerates pressures up to 10 psi without additional clamping hardware.

Sustained operation

The nitrile lip handles animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils while rotating at up to 3,720 RPM and a surface speed of 5.57 mps. It is not suited for applications that exceed these speed or pressure limits or that require multiple sealing lips.

Questions about this item

How fast can the shaft turn before the seal reaches its limit?

The seal is rated for a maximum rotational speed of 3,720 RPM.

What temperature rise or power draw should I expect when the seal runs continuously?

The seal is a passive component with no power draw; heat generation depends on shaft speed and lubrication rather than the seal itself.

Which shaft diameter and housing bore must I already have for this seal to fit?

The seal requires a 1.125 in shaft and a 2 in housing bore to match its inside and outside diameters.
