811 Series and 812 Series Cylindrical Roller Thrust Bearings
811 Series and 812 Series cylindrical roller thrust bearings are single direction thrust roller bearings designed to support heavy axial loads in compact bearing arrangements. TFL supplies a wide range of metric 811 and 812 series bearings, including popular models such as 81102 TN, 81106 TN, 81110 TN, 81206 TN, 81210 TN, and 81212 TN.
These bearings are commonly supplied as complete thrust bearing sets or matched components, including roller and cage thrust assemblies, shaft washers, and housing washers. For buyers seeking SKF interchangeable cylindrical roller thrust bearings, TFL provides model matching, dimensional checking, and global delivery support.
811 vs. 812 Series Cylindrical Roller Thrust Bearings
The 811 series and 812 series cylindrical roller thrust bearings are both single direction thrust bearings designed to support high axial loads. The 811 series is commonly selected when the application requires a compact bearing arrangement with reliable axial load capacity, while the 812 series is generally wider and offers higher axial load capacity in many comparable bore sizes.
For example, buyers often compare models such as 81110 TN and 81210 TN when the shaft diameter is the same but the required axial load capacity and available mounting space are different. If the equipment has limited axial space, the 811 series may be preferred. If the machine requires stronger thrust load support, the 812 series is often considered. TFL helps customers confirm the correct series based on bore diameter, outer diameter, width, load rating, speed, and matching washer components.
Complete Bearing Sets and Separate Components
811 and 812 series cylindrical roller thrust bearings are typically composed of three main elements: a roller and cage thrust assembly, a shaft washer, and a housing washer. In many applications, these components are installed together as a complete thrust bearing set to provide stable axial load support and smooth rolling contact between the shaft and housing.
Common component designations include K 811 / K 812 roller and cage thrust assemblies, WS 811 / WS 812 shaft washers, and GS 811 / GS 812 housing washers. For example, a bearing such as 81110 TN may correspond with K 81110 TN, WS 81110, and GS 81110. This modular structure is useful for maintenance buyers because individual components can be identified, checked, and replaced when required.
When customers send a bearing number, drawing, or old component code, TFL can help verify whether a complete set or separate K, WS, and GS components are needed. This reduces mismatch risk during replacement and helps ensure the thrust bearing assembly fits the shaft, housing, and operating load conditions.
SKF Interchangeable Thrust Bearing Options
TFL supplies 811 and 812 series cylindrical roller thrust bearings with SKF interchangeable options for customers who need replacement bearings, equivalent components, or alternative sourcing support. These products are often requested by part numbers such as 81102 TN, 81110 TN, 81206 TN, 81210 TN, and related component numbers like K 81110 TN, WS 81110, and GS 81210.
Interchange matching is not only about the bearing number. For reliable replacement, TFL checks key parameters such as bore diameter, outside diameter, width, dynamic load, static load, cage material, maximum speed, and washer compatibility. This is especially important for cylindrical roller thrust bearings because the roller and cage assembly, shaft washer, and housing washer must work together correctly under axial load.
For OEM factories, distributors, and maintenance buyers, TFL can support cross-reference checking, mixed-model order consolidation, and export-ready packaging. Customers can send SKF numbers, existing bearing markings, drawings, or sample photos, and our team will help identify suitable 811 or 812 series cylindrical roller thrust bearing options before shipment.
FREQUENTLY ASKED QUESTIONS
What is the difference between 811 and 812 series cylindrical roller thrust bearings?
Both are single direction cylindrical roller thrust bearings. The 811 series is generally more compact, while the 812 series is usually wider and designed for higher axial load capacity in comparable bore sizes.
Can TFL supply SKF interchangeable 811 and 812 series bearings?
Yes. TFL can help match SKF interchangeable 811 and 812 series cylindrical roller thrust bearings, including complete bearing sets and separate K, WS, and GS components.
What components are included in an 811 or 812 thrust bearing set?
A complete set usually includes a roller and cage thrust assembly, a shaft washer, and a housing washer. For example, an 81110 TN bearing may correspond with K 81110 TN, WS 81110, and GS 81110 components.
Which 811 and 812 series models are commonly requested?
Commonly requested models include 81102 TN, 81106 TN, 81110 TN, 81206 TN, 81210 TN, 81212 TN, 81120 TN, and 81220 TN, depending on bore size, axial load requirement, and installation space.
