■Corrosion ResistanceThe following list shows the comparison of corrosion resistance performance between AISI 440C stainless steel and AISI 52100 normal bearing steel. Please consult with us regarding any other chemicals not listed below.

［Remarks］This comparison list is provided as general guidance for the users. The performance level of corrosion resistance varies, depending upon the conditions of each application. Therefore, we recommend that the user conduct actual testing to see how 440C stainless steel works in the user-specific applications. We are not responsible for any claims taken place in the users’ applications without actual testing.

Under high temperature environment, radial internal clearance decreases due to difference of materials used for shaft, i.e. linear expansion coefficient, which may interfere with the rotation of the bearing. Please consider the thermal expansion sufficiently and select fitting and material of the shaft. Please contact us for further information.

The adequate fit is maintained between the bearing and the housing because no difference occurs in the amount of expansion and contraction by using AISI440C stainless steel for both components.

Best used for the applications that require precise positioning by the precision finishing. As for SSCXA and SSXC types, shaft can be easily fastened with set screws.

Both bearing and housing made of AISI440C stainless steel are superior for corrosion resistance and clean environment, therefore suitable for use in food machinery, equipment in clean room, chemical processing machine, cleaning equipment, and equipment that should look beautiful.

Aligning function can reduce the stress on the bearing by the error of shaft center and by the flexure of the shaft.

SMT SF series are high-precision flanged bearing units made with single low deep groove stainless bearing and stainless bearing housing, that can be fixed directly to machine and equipment easily with four bolts. SMT bearing units can contribute significantly to cost reduction by simplified facility design and improved work efficiency.

Selection of grease is an important factor to bring out the performance of the bearing.SMT can make the bearings filled with special grease

compliant to the use conditions upon requestwith short delivery and in small lot size.

＊The above information is subject to change without prior notice.

Other greases are also available.

Greases that we do not have in stock can be filled if supplied.

● Food grade grease compliant to H1 grade● Greases for use in vacuum environment● Greases for use in extreme temperature● Greases for use in watery environment

● Low emission greases for clean room● Low torque greases for low starting torque● Greases in your hand
