K893 Series and K894 Series
K893 Series and K894 Series cylindrical roller thrust assemblies are double row roller and cage assemblies used in heavy-duty thrust bearing arrangements. Unlike complete 893 and 894 series bearing sets, K893 and K894 assemblies include the cylindrical rollers and cage only, and are normally matched with separate shaft washers and housing washers.
These assemblies are designed for applications requiring high axial load capacity, compact internal replacement, and reliable load distribution. They are commonly used when the original thrust bearing arrangement already has suitable raceways, or when the customer needs to replace only the worn roller and cage assembly while keeping the matched washers or surrounding bearing structure.
TFL supplies SKF interchangeable K893 and K894 series thrust assemblies for distributors, OEM factories, repair companies, and industrial maintenance buyers. Customers can provide the original part number, washer codes, bearing drawings, or sample photos for model confirmation.
Double Row K Assemblies for Heavy Thrust Bearing Arrangements
K893 and K894 series assemblies are designed as double row cylindrical roller and cage units for thrust bearing arrangements with demanding axial load requirements. Their double row roller layout provides a larger contact area than single row K assemblies, helping improve axial load distribution, rigidity, and operating stability in heavy equipment.
The K893 series is often selected where the bearing arrangement needs strong thrust capacity while keeping the assembly relatively compact. The K894 series is normally used for heavier-duty positions where larger roller diameter, wider construction, and higher load ratings are required.
This page is focused on the K assembly itself, not the complete 893 or 894 bearing set. It is useful for buyers who need to replace the internal roller and cage unit, rebuild an existing thrust bearing arrangement, or source a compatible assembly for equipment that already uses separate WS and GS washers.
Raceway and Washer Matching for K893 and K894 Assemblies
Selecting the correct K893 or K894 cylindrical roller thrust assembly depends on more than the part number. Buyers often need to confirm the bore diameter, outside diameter, roller diameter, raceway diameter range, cage material, and matching washer codes before placing an order.
If you are not sure whether you need only the K roller and cage assembly or a complete 893/894 bearing set with WS shaft washer and GS housing washer, you can contact TFL for selection support. Our team can help check your old bearing number, drawing, bearing photo, or equipment information.
For maintenance replacement, SKF interchange, or heavy-duty thrust bearing projects, send us the available information and we will help identify the suitable K893 or K894 assembly for your application.
SKF Interchangeable K893 and K894 Replacement Support
Many procurement teams search for K893 and K894 series assemblies by SKF part numbers because these components are often used inside heavy-duty thrust bearing arrangements. TFL supports SKF interchangeable K 893 and K 894 assemblies, including common models such as K 89312 TN, K 89412 TN, K 89420 M, and K 89430 M.
For replacement projects, it is important to confirm whether the original component is a K roller and cage assembly or a complete 893/894 bearing set. This distinction helps avoid ordering the wrong product, especially when the old bearing marking only shows part of the full assembly code.
TFL supports model verification for industrial maintenance, gearbox repair, press equipment, extrusion machinery, marine equipment, and heavy transmission systems. Customers can send a bearing photo, old SKF number, washer code, machine drawing, or dimensional information, and TFL will help identify the correct K893 or K894 replacement option.
FREQUENTLY ASKED QUESTIONS
What is the difference between K893/K894 assemblies and 893/894 bearings?
K893 and K894 assemblies include only the cylindrical rollers and cage. Complete 893 and 894 bearings usually include the roller and cage assembly, shaft washer, and housing washer. If you only need to replace the internal cage assembly, K893 or K894 may be the correct choice.
Do K893 and K894 assemblies need shaft washers and housing washers?
Yes. K893 and K894 roller and cage assemblies normally need suitable raceways, often provided by matching WS shaft washers and GS housing washers. The washer codes should be checked before purchase to avoid incorrect matching.
What is the difference between K893 and K894 series?
The K893 series is generally more compact, while the K894 series is used for heavier axial load requirements and larger bearing arrangements. Selection depends on shaft size, raceway dimensions, load rating, speed, and available installation space.
Can TFL supply SKF interchangeable K893 and K894 assemblies?
Yes. TFL can supply SKF interchangeable K893 and K894 cylindrical roller thrust assemblies. Customers can provide the SKF part number, old bearing marking, drawing, or sample photo for cross-reference confirmation.
Where are K893 and K894 cylindrical roller thrust assemblies used?
They are used in heavy-duty thrust bearing arrangements for gearboxes, presses, extrusion machinery, steel mill equipment, marine machinery, mining equipment, and large industrial transmission systems.
