Deep groove ball bearings are suitable for high speed operation, are very durable and do not require frequent maintenance. This type of bearing has a small friction coefficient,  used in precision instruments, low-noise motors, automobiles, motorcycles and general machinery and other industries, it is the most widely used type of bearing in the machinery industry. It mainly bears radial load, and can also bear a certain amount of axial load. The most common deep groove ball series are 6000 series, 6200 series, 6300 series, 6400 series.

Single row cylindrical roller bearing is usually only subject to radial force, compared with the ball bearing of the same size, the radial bearing capacity is increased by 1.5-3 times, good rigidity, impact resistance, it is especially suitable for rigid support, and support the short shaft, heat elongation caused by axial displacement of the shaft and the installation and disassembly of the machine accessories need separation type bearing.

Spherical Roller Bearing: The outer ring is a sphere with the center point of the bearing as the ball center, with automatic aligning, linear contact between the rolling body and the inner and outer ring raceway and can withstand large radial load. Suitable for mining, metallurgy, paper making, construction and other large machinery and equipment.

Tapered roller bearings are separated bearings, and the inner and outer rings of the bearings are equipped with tapered raceways. This kind of bearing is divided into single row, double row and four row tapered roller bearings and other different structural types according to the number of rows of rollers installed, and is widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.

Service OEM service provided Delivery time 3-15 days depends on quantity needed     Structure:  This type of bearing is equipped with a round platform roller, the roller by the inner ring of the large rim. Single row bearings can bear radial load and unidirectional axial load, and double row bearings can bear radial load and bidirectional axial load.Suitable for bearing heavy load and shock load. According to the different contact Angle (α), it can be divided into three types: small cone Angle, middle cone Angle and large cone Angle. The larger the contact Angle is, the greater the axial load capacity is. Outer ring and inner assembly (inner ring and roller and cage assembly) can be separated for easy assembly and disassembly. Bearings with rear auxiliary code "J" or "JR" have international interchangeability.         Common uses of tapered roller bearings A tapered roller bearing is appropriate wherever a bearing must handle combination loads. One of the most common uses is maintaining axial balance, achieved with multiple tapered roller bearings along an axle or shaft. The tapered bearings will evenly distribute loads when adequately aligned, minimizing wear and tear on the components. With higher surface area, tapered roller bearings can distribute friction and heat from combination loads more efficiently than non-tapered rollers (which are more efficient than tapered bearings only with the most straightforward non-combination forces). This reduced friction increases the rotational speed of interfacing parts and makes tapered roller bearings ideal for use in: Engines Motors Gearboxes (especially those with helical gears) Wheels & axles Turbines & propellers This equipment must combine many different angles and utilize them to drive motors, driveshafts, and other rotational components.

A Pillow Block Bearing is a mounted anti-friction bearing that is contained within a solid cast iron, ductile iron or cast steel housing unit. Also referred to as a housed bearing unit, meaning they are self-contained, greased, sealed and ready for installation on the equipment.

The WHA is located between the brake drums or discs and the drive axle. A wheel is bolted on it. Depending on the construction, the end of the hub comes equipped with the splined teeth. They mate the teeth on the axle shaft. The axle hub spins along with the wheels bolted to it and provide power to the wheels in order to rotate. A roller bearing between the axle hub and axle shaft ensures easy rotation of the non-drive wheels. On the axle side, it is mounted to the holding bracket from the chassis; on the disc side, the wheel is mounted to the bolts of the WHA. When replacing, a wheel hub assembly should be torqued to the vehicle's specifications to prevent failure.
