China Suppliers - High-Quality Wear Resistant Thrust Roller Bearings from Factory for Heavy Axial Loads
Types of Thrust Roller Bearings
Cylindrical Thrust Roller Bearings
Use cylindrical rollers for high axial load capacity.Example: 811, 812 series (e.g., 81115, 81215).
Tapered Thrust Roller Bearings
Utilize tapered rollers to handle combined axial and radial loads (axial dominant).Example: 893, 894 series.
Spherical Thrust Roller Bearings
Feature spherical rollers and self-aligning capability (±2°). Compensate for misalignment between shaft and housing.Example: 292, 293 series.
Key Features
- ⚡High Axial Load Capacity: Optimized roller design and material for extreme loads.
- 🔄Low Speed Suitability: Ideal for slow-rotation heavy-duty applications.
- 🔩Rigidity: Provides stable support under high-stress conditions.
- 🔧Separable Design: Shaft/housing washers and roller assemblies can be mounted separately.
Design Variants
Single-Direction
Handles axial loads in one direction.e.g., 811 series
Double-Direction
Accommodates bidirectional axial loads.e.g., 893 series

Frequently Asked Questions
QWhat is the main difference between cylindrical and spherical thrust roller bearings?
Cylindrical thrust roller bearings use straight cylindrical rollers and are designed purely for high axial loads with no misalignment tolerance. Spherical thrust roller bearings use barrel-shaped rollers and offer self-aligning capability of up to ±2°, making them suitable for applications where shaft-to-housing misalignment is unavoidable.
QCan thrust roller bearings handle radial loads?
Thrust roller bearings are primarily designed for axial loads. Their radial load capacity is very limited — generally no more than 5% of the axial load rating. For applications with significant combined loads, tapered thrust roller bearings (e.g., 893/894 series) offer the best combined load handling.
QWhat cage material should I choose for high-temperature environments?
For high-temperature applications, machined brass cages (suffix MB) are the recommended choice. They offer superior thermal stability compared to stamped steel or polyamide cages. Polyamide (TVP) cages are only suitable for moderate temperature ranges and should be avoided in extreme heat conditions.
QWhat lubrication is recommended for thrust roller bearings?
For high-load, low-speed operations — which are typical for thrust roller bearing applications — grease or oil-based lubricants are both suitable. The choice depends on operating temperature, speed, and sealing requirements. Always ensure the lubricant is compatible with the cage material and the bearing's operating temperature range (-30°C to +200°C).
QWhat precision grades are available for thrust roller bearings?
Thrust roller bearings are available in standard tolerance grade P0 for general industrial use, as well as precision grades P6 and P5 for applications requiring tighter dimensional accuracy and reduced runout, such as precision gearboxes or aerospace systems.
QAre thrust roller bearings separable, and does that affect installation?
Yes, thrust roller bearings feature a separable design — the shaft washer, housing washer, and roller-cage assembly can all be mounted independently. This simplifies installation and removal, especially in tight or complex assemblies. However, non-self-aligning types still require precise shaft-to-housing alignment during installation to avoid premature wear or failure.
