Wear Resistant Thrust Roller Bearings from China - Reliable Suppliers and Factory for Heavy Axial Load Applications
Types of Thrust Roller Bearings
Use cylindrical rollers for high axial load capacity.
Example: 811, 812 series (e.g., 81115, 81215).
Utilize tapered rollers to handle combined axial and radial loads (axial dominant).
Example: 893, 894 series.
Feature spherical rollers and self-aligning capability (±2°).
Compensate for misalignment between shaft and housing.
Example: 292, 293 series.
Key Features
Optimized roller design and material for extreme loads.
Ideal for slow-rotation heavy-duty applications.
Provides stable support under high-stress conditions.
Shaft/housing washers and roller assemblies can be mounted separately.
Design Variants
Handles axial loads in one direction (e.g., 811 series).
Accommodates bidirectional axial loads (e.g., 893 series).
Standard design for uniform load distribution.
Self-aligning for misalignment compensation (e.g., 294 series).
Cage Types
Economical and widely used (standard for most series).
For high-temperature or high-speed applications (suffix MB).
Lightweight and suitable for moderate temperatures (suffix TVP).
Applications
-
Heavy Machinery: Crane hooks, hydraulic jacks, extruders.
-

Technical Specifications
Installation Notes
-
Requires perfect alignment between shaft and housing (non-self-aligning types).
-
Preload may be applied for enhanced rigidity in precision systems.
-
Lubrication: Grease or oil-based lubricants for high-load/low-speed operations.
Advantages
Up to 300% higher than thrust ball bearings.
Robust construction for shock and vibration resistance.
Options for special materials, coatings, and seals.
Frequently Asked Questions
The three main types are Cylindrical Thrust Roller Bearings (for high axial loads), Tapered Thrust Roller Bearings (for combined axial and radial loads), and Spherical Thrust Roller Bearings (which offer self-aligning capabilities).
Thrust roller bearings provide an exceptional axial load capacity that is up to 300% higher than standard thrust ball bearings.
They are designed primarily for axial loads. Their radial load capacity is typically limited to 5% or less of their axial load rating.
No. Non-self-aligning types (like cylindrical and tapered) require perfect alignment between the shaft and housing. Only Spherical Thrust Roller Bearings feature self-aligning capabilities (up to ±2°).
Stamped Steel cages are the standard economical choice; Machined Brass cages (suffix MB) are used for high-temperature or high-speed applications; and Polyamide cages (suffix TVP) are lightweight and designed for moderate operating temperatures.
