China Thrust Cylindrical Roller Bearings - Suppliers & Factory Direct High-Rigidity Solutions

Thrust cylindrical roller bearings are specialized thrust rolling bearings that utilize cylindrical rollers as their rolling elements. These bearings feature a robust design comprising a shaft washer, a housing washer, and a thrust cylindrical roller and cage assembly, which together form the essential core component. Engineered to handle significant unidirectional axial loads and vibration loads, these bearings lack self-aligning capability, making them ideal for applications requiring high rigidity, As leading manufacturers and suppliers in China, we offer a range of models including the 811 series, 812 series, 81115, and 8121Our factory is committed to delivering high-quality thrust cylindrical roller bearings that meet the diverse needs of various industries. Trust our products for their durability and reliability in demanding environments

    Product Details

    Product Introduction

    The cylindrical rollers are crowned to optimize raceway contact pressure distribution, enhancing axial load capacity and rigidity. These bearings are suitable for low-speed machinery requiring unidirectional axial load support, such as crane hooks, vertical water pumps, jacks, oil drilling rigs, and iron and steel manufacturing equipment.

    ▶ The shaft washer, housing washer, and rolling elements can be installed separately.

    Cages

    Thrust cylindrical roller bearings may use:

    ● Molded glass fiber-reinforced polyamide 66 cages (designated as: TVPB, TVPB1).
    ● Machined lightweight metal cages (designated as LPB).
    ● Machined brass cages (designated as MB, MPB).

    These bearings can withstand very high unidirectional axial loads but cannot carry radial loads. They do not have self-aligning capability.

    Thrust cylindrical roller bearings can be disassembled into:

    ● Thrust cylindrical roller and cage assembly
    ● Shaft washer
    ● Housing washer

    The 811 series and 812 series thrust cylindrical roller bearings consist of a thrust cylindrical roller and cage assembly, a shaft washer, and a housing washer. The most critical component is the thrust cylindrical roller and cage assembly.

    Frequently Asked Questions

    Q What types of loads can thrust cylindrical roller bearings support?
    Thrust cylindrical roller bearings are designed to support very high unidirectional axial loads. They cannot carry radial loads and do not have self-aligning capability.
    Q What is the purpose of the crowned cylindrical rollers?
    The crowning on the cylindrical rollers optimizes the raceway contact pressure distribution, which enhances both axial load capacity and overall bearing rigidity during operation.
    Q What cage materials are available for thrust cylindrical roller bearings?
    Three cage types are available: molded glass fiber-reinforced polyamide 66 cages (TVPB, TVPB1), machined lightweight metal cages (LPB), and machined brass cages (MB, MPB). The choice depends on the application's speed, temperature, and load requirements.
    Q Can the components of thrust cylindrical roller bearings be installed separately?
    Yes. The shaft washer, housing washer, and rolling elements are separable, allowing each component to be installed independently. This simplifies assembly and maintenance in tight or complex machine configurations.
    Q What are the typical applications for thrust cylindrical roller bearings?
    These bearings are commonly used in low-speed machinery that requires unidirectional axial load support, including crane hooks, vertical water pumps, jacks, oil drilling rigs, and iron and steel manufacturing equipment.
    Q What is the difference between the 811 series and 812 series thrust cylindrical roller bearings?
    Both the 811 and 812 series share the same basic structure — a thrust cylindrical roller and cage assembly, a shaft washer, and a housing washer. The series differ primarily in their dimensional specifications and load ratings, making each suited to different application size and load requirements.
