Spherical Roller Bearings
HZK Spherical roller bearings excel in durability and performance, even in demanding environments and operating conditions. These bearings have a unique design with self-alignment capability in the outer ring, which is based on the curvature of the raceway and rolling elements.
Cylindrical Roller Bearings
Cylindrical Roller Bearings are bearing in which cylinders are used as the rolling elements as opposed to balls in ball bearings. As such, the rollers have a greater (linear) contact area with the outer ring and are distribute loads across a broader surface. Subsequently, they have a relatively high radial load capacity and are suitable for high speeds. Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.
Deep Groove Ball Bearings
HZK Deep Groove Ball Bearings consist of an outer ring, an inner ring, a set of steel balls, and a cage. Deep groove ball bearings are available in single-row and double-row configurations. Deep groove ball bearings are also classified into sealed and open configurations. Open configurations are unsealed, while sealed deep groove ball bearings are classified into dust-proof seals and oil-proof seals. Dust-proof seals are stamped from steel and simply prevent dust from entering the bearing raceways. Oil-proof configurations use contact seals, effectively preventing grease from escaping the bearing.
Tapered Roller Bearings
HZK single row tapered roller bearings adopt TIMKEN technology. Its size is mainly determined by the diameter, width, thickness and other parameters of the inner ring, outer ring, tapered roller and cage. The inner ring diameter, outer ring diameter and roller diameter are important indicators that determine the bearing's load capacity. Generally, single row tapered roller bearings are suitable for applications that require large radial and axial forces.
Thrust Spherical Roller Bearings
HZK Thrust Roller Bearings are designed for practicality and durability. Their rollers are typically cylindrical or conical, which helps distribute loads and reduce contact stresses. Cages secure the rollers, preventing them from colliding or shifting during operation. Washers guide the rollers' movement and help the bearings accommodate axial loads. The material selection for these components is also crucial; common materials include high-carbon chromium bearing steel, which offers high hardness and wear resistance, extending the bearing's service life.
Angular Contact Ball Bearings
HZK Angular Contact Ball Bearings primarily support large, unidirectional axial loads. The larger the contact angle, the greater the load capacity. Cage materials include steel, brass, or engineering plastics, and molding methods include stamping or turning, depending on the bearing type and operating conditions. Other bearings include combined angular contact ball bearings, double-row angular contact ball bearings, and four-point contact ball bearings.
Pillow Block Bearings
Insert ball bearings with set screws are available in the UC200 series, UC300 series, and their variant, the UB(SB)200 series. If the application environment is less suitable, the UC200 series is generally selected; otherwise, the UC300 series is preferred. Insert ball bearings typically have two set screws, angled 120° apart. Their characteristic is that they use the set screws to secure the shaft when mating. However, the mating environment requires minimal vibration. This type of insert ball bearing is quite common and is widely used in various manufacturing industries, including textile machinery and ceramic machinery.
