SF series - AISI440C Flanged Bearing Units

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.

Features

Corrosion Resistance

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(SSA and SSXCA types)

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

Fit

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.

Mounting

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.

Bearing can be dismounted from housing. Location of set screw can be reversed.

Precautions

Please refer to the charts for the tightening torque. Too much torque may damage the bearing. Adhesive bond is not recommended that may increase the tightening force and result in the breakage of bearing.

Set screw recommended torque

Sizes	Torque N.m
M3	0.7
M4	1.8
M5	3.0
M6	4.0

Mounting bolt recommended torque

Sizes	Torque N.m
M4	1.8
