China Thrust Cylindrical Roller Bearings Factory - Suppliers of High-Rigidity Axial Load Solutions

Thrust cylindrical roller bearings are specialized thrust rolling bearings that utilize cylindrical rollers as their rolling elements. These bearings feature a design comprising a shaft washer, a housing washer, and a thrust cylindrical roller along with a cage assembly, which is crucial for their operation. Engineered to handle unidirectional heavy axial loads and vibration, these bearings lack self-aligning capabilities, making them ideal for high-rigidity configurations when used in combination. Popular models include the 811 series, 812 series, 81115, and 8121As leading suppliers from China, we ensure top-quality thrust cylindrical roller bearings manufactured in our state-of-the-art factory, meeting the highest standards to satisfy your application needs

    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 is the purpose of crowning the cylindrical rollers in thrust bearings?
    Crowning optimizes the contact pressure distribution across the raceway, which reduces edge stress concentrations, enhances axial load capacity, and improves overall bearing rigidity and service life.
    Q Can thrust cylindrical roller bearings support radial loads?
    No. These bearings are designed exclusively for unidirectional axial loads. They cannot carry radial loads and do not have self-aligning capability, so proper shaft and housing alignment is essential during installation.
    Q What cage materials are available for thrust cylindrical roller bearings?
    Three cage types are available: molded glass fiber-reinforced polyamide 66 (TVPB, TVPB1), machined lightweight metal (LPB), and machined brass (MB, MPB). The choice depends on operating speed, temperature, and load conditions.
    Q What are the main components of the 811 and 812 series thrust cylindrical roller bearings?
    Both series consist of three separable components: the thrust cylindrical roller and cage assembly, the shaft washer, and the housing washer. The roller and cage assembly is considered the most critical component.
    Q What types of machinery are thrust cylindrical roller bearings typically used in?
    They 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 Can the components of thrust cylindrical roller bearings be installed or replaced separately?
    Yes. The shaft washer, housing washer, and rolling elements are separable, allowing each component to be installed, inspected, or replaced independently. This simplifies maintenance and reduces downtime.
