■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.

■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.

Application
Heat-resistant bearing, made of AISI
440C stainless steel with
heat-resistant �uorine grease, can be
supplied with short delivery in small
lot like even one piece.
Heat-resistant Stainless Bearings
Device around furnace, oven, heater, drying equipment, and other high temperature area.
1. AISI 440C stainless steel has lower hardness decrease ratio and smaller dimension changes than SAE 52100 bearing steel in high temperature environment.
2. AISI 440C stainless steel is superior to SAE 52100 bearing steel in oxidation resistance in high temperature environment.
3. Filling heat-resistant �uorine grease enables lubrication in high temperature environment.
1. Hybrid type incorporating ceramic balls into outer and inner rings of AISI 440C stainless steel
2. Longer grease life, by lower heat generation with ceramic balls
3. Less running cost by longer lifetime
4. Material characteristics*1 Sealed type available up to 392ºF

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.

Roller for chemical film conveyor, clean room application, food machinery, glass substrate conveyor, cleaning system, papermaking machine, printing machine, etc.
Application
1200/1300 series Combination with SS XC series bearings with set screw
Deep Groove Ball Bearing SH series
1. Corrosion Resistance
Interchangeable to 6200, 6300, 1200 and 1300 series bearings. The dimensions are the same, except the width of the bearing inside.
4. Interchangeability
The SH series bearings have more advantages than the standard self-aligning bearings made of SAE52100 steel.
5. Other
2. Aligning Function
Addition of aligning function to standard stainless ball bearings can
allow them to require less maintenance by allowing the flexure of large
roller, together with corrosion resistance of stainless steel.
Available with seals and shields, and suitable in dusty or watery environment.

Flexure
dust cleaning liquid
SH seriesStainless Ball Bearing with Aligning Ring
Reducing the excess strain on bearing, by aligning the flexure of the conveyor roller’s shaft or the error of shaft center.
excess strain less strain
SH series
SH series
Made of AISI440C stainless steel, and suitable in corrosive environment, in clean room and for food machinery.
Roller for chemical film conveyor, clean room application, food machinery, glass substrate conveyor, cleaning system, papermaking machine, printing machine, etc.
Application
1200/1300 series Combination with SS XC series bearings with set screw
Deep Groove Ball Bearing SH series
1. Corrosion Resistance
Interchangeable to 6200, 6300, 1200 and 1300 series bearings. The dimensions are the same, except the width of the bearing inside.
4. Interchangeability
The SH series bearings have more advantages than the standard self-aligning bearings made of SAE52100 steel.
5. Other
2. Aligning Function
Addition of aligning function to standard stainless ball bearings can
allow them to require less maintenance by allowing the flexure of large
roller, together with corrosion resistance of stainless steel.
Available with seals and shields, and suitable in dusty or watery environment.

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.
