SMT STAINLESS STEEL BALL BEARINGS
 
As performance level of precision machinery has risen, the range of applications using ball bearings has become broader, and the demand for higher performance and durability of ball bearings has increased. Industrial needs for ball bearings having high anti-corrosion technology and the ability to withstand fierce conditions while maintaining the preciseness of ball bearings originally required have also increased.

SMT stainless steel ball bearings are the products that comply with current industrial needs.

SPECIAL FEATURES

1.

High resistance to corrosion
2. High stability in high temperature (Higher available operating temperature by approximately 50 degrees C, or, 122 degrees F than normal bearing steel)
3. High resistance to chemicals

MATERIALS

AISI 440C martensitic stainless steel is used for inner rings, outer rings and balls. AISI 304 austenitic stainless steel is used for retainers and metal shields. Standard material of rubber seals is nitrile butadiene rubber (NBR), and other materials such as fluorinated rubber, acrylic rubber, etc. are available upon request.
440C stainless steel is magnetized steel.
 

PRECISION SPECIFICATION

Dimension tolerance and rotational precision grade over ISO Normal Class or ABMA(used to be AFBMA)ABEC-1 is guaranteed. ISO CLASS 6 or ABEC-3 and ISO CLASS 5 or ABEC-5 are also available upon request.
 

LUBRICATION

Heat-resistant grease is prepacked in SMT 's shielded and sealed type stainless steel ball bearings. Special high temperature greases such as silicon grease, fluorinated grease, etc. are available for special applications upon request.
