Product Description

1.3505 Bearing Steel Balls 52100 Chrome Steel Balls For Mountain Bike Part 5/16

 

 

Steel balls for bearings are generally made from chrome steel.

 

Many steel balls for bearings such as AISI 52100 100 Cr6 have a hardness of between 60 - 66

 

and ultimate compressive strength of 2500 - 2600 although 100CrMn6

 

chrome steel balls are a good alternative when a higher core strength is required.

 

Characteristics

 

Low alloy hardened chromium steel balls
 
excellent hardness
 
wear resistance,
 
very good surface finishing and dimensional stability.
 
Applications
 
Low alloy martensitic chrome steel or AISI 52100 steel balls for bearings
 
are valued for their hardness, resistance to wear and surface finishing.
 
Common applications include precision bearings and automotive components
 
such as brakes, line shaft and steering mechanisms.
 
Other uses include machine tools, rollerball and ballpoint pens,
 
cosmetics, furniture and appliance castors and precision measuring instruments.

More Information

 

 large chrome steel balls are designed to be more durable than conventional AISI 52100 based varieties.

 

Instead, we use 100CrMn6 to achieve a harder core, which ensures a longer lifetime and better performance.

These balls have a hardness rating of between 60 and 66 HRC, which makes them resistant to wear, and

 

an ultimate compressive strength of 2500 - 2600 MPa, which allows them to handle heavy loads.

At the same time, these chrome steel balls are also engineered to function at temperatures of between -60 and

 

150 degrees centigrade, making them suitable for a variety of environmental situations.

With these specifications, you will often find our precision steel balls in windmill mechanisms,

 

where large diameter components are essential. They help to supply clean electricity across the world,

 

and are also a feature of many industrial motors and mechanisms (eg for bicycle).
