Our 6214 2RS Bearing is a type of deep groove ball bearing that is designed to provide optimal performance in a wide range of applications. The bearing is made of high-quality materials that are durable and long-lasting, ensuring that it can withstand even the most demanding conditions. The bearing is designed to reduce friction and increase efficiency, providing a smooth and reliable operation for your machinery.
One of the key features of our 6214 2RS Bearing is its double rubber seals. These seals are designed to keep the bearing lubricated and protected from dust, dirt, and other contaminants. This makes the bearing ideal for use in harsh environments where other bearings may fail due to exposure to these elements.
In addition to its double rubber seals, the 6214 2RS Bearing also has a steel cage that provides additional support and helps to distribute the load evenly. This helps to reduce wear and tear on the bearing, extending its lifespan and reducing maintenance costs.
Our 6214 2RS Bearing has a bore diameter of 70 mm, an outside diameter of 125 mm, and a width of 24 mm. This makes it suitable for use in a wide range of applications, including machinery, automotive, and industrial equipment.

● Introduction
6214 2RS bearing belongs to single row deep groove bearings. Deep groove ball bearings are simple in structure, easy to achieve high manufacturing accuracy and mass production in series compared with other types, and also have lower manufacturing cost, so they are the widely used bearings. The vibration of the bearings conforms to the national standard JB/T 10187-2011. The vibration level of bearings is divided into V,V1,V2,V3 and V4. In principle, group Z and V are the basic requirements for the performance of bearings, which should be met by all bearings of inspection and. The rest of the groups are used when the bearings have higher requirements for vibration. The steel balls conform to standard GB/T 308.1-2013, steel balls are made of GCr15. The great contact stress is generated between balls and rings when bearings are subjected to large local alternating loads during operation, so the bearing steel is required to have high hardness, wear resistance, sufficient fatigue strength, certain toughness and corrosion resistance, good dimensional stability, etc.
Bearings are widely used in precision instruments, transportation vehicles, agricultural machinery, agriculture and other fields.
● Production Details
Annealing defects underheating causes, due to low heating temperature, insufficient holding time, or loading capacity, furnace temperature uniformity caused by poor. Need to develop a reasonable annealing process. Or improve the furnace temperature uniformity, or control a reasonable amount of loading, placed evenly. The size of the grinding allowance on both ends. In double endface grinding, it is better to have equal grinding allowance on both ends of the ring, which is sufficient for a ring with equal grinding area on both ends, as long as the grinding wheel speed on both sides is the same. For rings with unequal grinding areas, we can achieve this by adjusting the speed of the grinding wheels on both sides or trimming the size of the grinding wheels. Quenching and tempering after cracking is mainly due to quenching tissue overheating, quenching oil water content of more than 0.5%, or the ring is a sharp angle part of the stress concentration. Quenching temperature should be reduced, control the quenching oil water content, or minimize the stress of the collar. In addition, the reasonable arrangement of the process route, choose the appropriate quenching method, etc.

● Tolerance and Radial Clearance Standard
The fit of bearing inner ring and journal is tighter than the GB/T1801-1999 base hole system with the same name. g5, g6, h5, h6 journal and bearing inner ring have become transition fit, k5, k6, m5, m6 have become interference fit, and the rest are also tightened.

● Bearing Quality
The correct choice of fit, to prevent too tight, because the elastic expansion of the inner ring and the contraction of the outer ring will make the internal clearance of the bearing reduce or even completely eliminate and produce interference, not only affect the normal operation, but also make the collar material to produce a large stress, to reduce the service life of the bearing.
