Q: What type of bearing parts does Hartford Technologies produce?

Answer: Bearing race/bearing ring – The bearing race is usually made of high-quality bearing grade chromium steel, which is valued for its excellent mechanical properties (tensile strength, hardness, wear resistance). Precision machining and grinding processes are used to manufacture these components, which must withstand high speed and load during operation.

Bearing cage/separator - used to fix rolling elements (ball or roller) in the correct direction, so that they will not gather together. It is usually made of stamped metal or molded plastic.

Retainer – used to keep rolling elements (ball or roller) in the correct direction so that they do not get together. It is usually made of stamped metal or molded plastic.

The rolling element is a ball or roller. The roller provides higher bearing capacity (theoretically, the contact point between the contact line and the ball).

Q: Why does the customer only search for bearing components instead of complete bearing components?

A: In many applications, multiple components may be used as bearing components together, but the end user has already produced some of them. Simple examples may include shafts that are also used as bearing cones or housings that are used as outer rings. In this case, the customer may only search for cages/separators and balls or rollers.
