    Cylindrical Roller Bearings

    The rollers of cylindrical roller bearings are usually guided by two ribs of a bearing ring. The cage, rollers and guide ring form an assembly that can be separated from another bearing ring and is a separable bearing. It is more convenient to install bearings and magnetic fields, especially when the interference fit between the inner and outer rings, the shaft and the shell is required.

    This type of bearing is generally only used to bear radial load. Only single row bearings with ribs on both the inner and outer rings can bear smaller axial load or large axial load intermittent.

    At ZMS, we specialize in providing high-quality cylindrical roller bearings. As a leading supplier in the industry, we offer a comprehensive selection of cylindrical roller bearings, including single-row, double-row, and four-row designs, engineered for both industrial and automotive applications.

    Needle Roller Bearings

    Needle roller bearings are a specialized type of roller bearings featuring cylindrical rollers with a length significantly greater than their diameter. They are widely used in automotive transmissions, industrial machinery, and aerospace applications due to their ability to efficiently handle high radial loads in constrained spaces. ZMS supplies wide range of needle roller bearings in different designs, series and sizes in high quality in China 15 years. Products Series:

    • Drawing cup needle roller bearings.
    • Needle roller bearings with machined rings.
    • Combined needle roller bearings.
    • Cam followers.
    • Yoke type track rollers.
    • Thrust needle roller bearings.
    • Inner rings.
    • One-way needle roller bearings.

    Spherical Roller Bearings

    Spherical roller bearings are mainly used to applications with high radial load. They are suitable for working under heavy load or vibration, but cannot withstand pure axial load.

    Spherical roller bearings have good alignment performance and can accommodate misalignment of shaft.

    ZMS has been a leading supplier of high quality spherical roller bearings to end users and host to different customers in different fields around the world for 15 years. We satisfy customers requirements from designing to manufacturing.

    Tapered Roller Bearings

    Tapered roller bearings consist of an inner ring (cone), an outer ring (cup), tapered rollers, and a cage (retainer) that holds the rollers in place.Due to their design, tapered roller bearings can support high radial and axial loads. Tapered roller bearings can be adjusted during installation to accommodate changes in clearance or preload due to temperature variations or manufacturing tolerances. They are widely used in applications include automotive wheel bearings, gearbox applications, and heavy machinery. ZMS supplies wide selection of tapered roller bearings in high quality we can supply customization production by different load,temperature, vibration and sealing requirements. Main series:

    • Single row tapered roller bearings.
    • Double rows tapered roller bearings.
    • Four rows tapered roller bearings.
