Thrust Cylindrical Roller Bearings - Quality Products from China Suppliers and Factory for Heavy Axial Loads
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, including applications such as:
🏗️ Crane Hooks
💧 Vertical Water Pumps
🔧 Jacks
🛢️ Oil Drilling Rigs
🏭 Iron & 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
811 Series
Consists of a thrust cylindrical roller and cage assembly, a shaft washer, and a housing washer.
812 Series
Consists 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
❓
What types of loads can thrust cylindrical roller bearings handle?
Thrust cylindrical roller bearings are designed to handle very high unidirectional axial loads. They cannot carry radial loads and do not have self-aligning capability.
❓
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).
❓
What are the typical application fields for thrust cylindrical roller bearings?
These bearings are widely used in low-speed machinery that requires unidirectional axial load support, such as crane hooks, vertical water pumps, jacks, oil drilling rigs, and iron and steel manufacturing equipment.
❓
Can the components of thrust cylindrical roller bearings be installed separately?
Yes. The shaft washer, housing washer, and rolling elements can all be installed separately, which provides flexibility during assembly and maintenance.
❓
What is the difference between the 811 series and 812 series thrust cylindrical roller bearings?
Both the 811 series and 812 series consist of a thrust cylindrical roller and cage assembly, a shaft washer, and a housing washer. The key difference lies in their dimensional specifications and load ratings, making each series suitable for different application requirements.
❓
Why are the cylindrical rollers crowned in thrust cylindrical roller bearings?
The crowning of cylindrical rollers is designed to optimize the raceway contact pressure distribution. This helps enhance the bearing's axial load capacity and overall rigidity, reducing stress concentrations at the roller edges.
