Description- GJP Vehicle Front Wheel Application Single Row Metric Tapered Roller Bearings 30211-RS-3B With Seals

GJP Bar Code Number: 6935329839274

GJP provide this metric tapered roller bearings with one side rubber seal, which is different from normal size, and it has the feature for the common tapered roller bearing, which has a tapered bore cup and and taper outer diameter cone with rubber black seal, normally this type of bearing has a 10°to 19°taper angle, and could afford axial loading and radial loading at the same time, the bigger taper angle has, the bigger afford this bearing could bear, if there is a suffix “B” on the items number, it means that this bearing is designed with bigger taper angler at around 25°to 29°,and all of these tapered roller bearings could be adjusted the clearance during the working environment.

GJP metric tapered roller bearings is widely used on Auotomotive, Mining, Rolling Mill, Metallurgy, Plastic production machinery.

GJP has been supplying this bearing to OEM market in automotive field, and we have advantage to provide this bearing:

1)We request to use the raw material from Jiangsu Xingcheng Steel Company.

2)We request to do the heat treatment according to the best advanced furnace for quenching, with the step of salt-bath bainite quenching and matensitequenching the uniformity of surface hardness can be well guaranteed, and the whole bearing race could be thoroughly heat treatment and hardened, so we could keep the products with the hardness range at HRC59-61, and make sure the hardness difference in one part is less than 1 degree, which leads GJP’s Bearings are more suitably applied for situation of high impact and high load.

Metric tapered roller bearings are separable bearings, and both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types such as single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers installed. Single row tapered roller bearings can withstand radial loads and axial loads in one direction. When the bearing is subjected to radial load, an axial component force will be generated, so when another bearing that can withstand axial force in the opposite direction is needed to balance it.

Structural characteristics of metric tapered roller bearings

The top of the metric tapered roller bearings are equipped with a tapered roller, which is a bearing unit composed of radial rollers and components. The inner and outer rings of the bearing have tapered raceways. Since the cross-sectional diameter of the roll is short, but the length is long, it is named tapered roller bearing according to the shape.

Characteristics of metric tapered roller bearings

Although the section diameter of this part is very short, the size and weight of the part itself are relatively small, but its radial structure is compact and has a high load capacity, so its inner diameter size and load capacity are compared with other types of bearings, the outer diameter small, especially suitable for the size constraints of radially mounted support structures.

On the other hand, the raceway of the outer ring of the bearing also plays a big role: the load capacity of the bearing is increased by increasing the angle of the contact surface.

In addition, the metric tapered roller bearings have high machining accuracy and high surface hardness, so it can withstand several times more force than its bearing force. Safe to use, tight connection and good performance.
