This kind of Bicycle Stainless Steel Ball Bearing is a type of rolling bearing. The spherical alloy steel ball is installed between the inner steel ring and the outer steel ring to reduce the friction during the power transmission process and improve the transmission efficiency of mechanical power by rolling. It mainly contains four basic components: ball, inner ring, outer ring and cage(or retainer). In addition, the Bicycle Stainless Steel Ball Bearing changes the friction mode of the bearing and adopts rolling friction to effectively reduce the friction between the bearing surfaces and improve the service life. Besides, it has the advantages of fast speed, low noise, rustproof, wear resistance, durability as well as sophisticated design. The Bicycle Stainless Steel Ball Bearing is generally used in low-load mechanical transmission equipment.
The quality of stainless bearing steel ball steel is not only stricter in all alloy steels, but also the most tested steel grade. It is recognized by the world that the level of bearing steel balls is a symbol of a national metallurgical level. The bearing steel ball has high requirements for its materials, and must have high hardness, wear resistance, contact fatigue strength, elastic limit, good impact toughness, fracture toughness, dimensional stability, anti-rust performance, and hot and cold processing properties.
Improvement Measures of Bearing Ball to Prevent Cracking Process
Forging Increase the forging ratio, forging process control strictly to prevent the forged heart organization coarse.
2. To reduce the bearing steel ball quenching water temperature, increase the water temperature, the workpiece quenching stress can be significantly reduced and mitigated.
3 before quenching increase spheroidizing annealing, refine the organization, so that after the workpiece was fine needle-like (fine tablets.) Martensite, to prevent the formation of coarse tissue after quenching.
4. Tempering after quenching in time to eliminate quenching stress, stable organization, to further remove the risk of cracking of the workpiece.
After precision washing, oiling & before packing sample balls from the batch are sent for final audit to check for surface roughness, roundness, waviness, lot size variation and hardness in a sophisticated laboratory, according to specified control plans and dock audit procedures. Once all requirements are met, a test certificate is then prepared for the customer. Our sophisticated laboratory is equipped with high precision, worldwide respected machines and equipment and is managed by properly trained and qualified personnel.
