AS8112WE Elastic Spiral Roller Bearing / AS8112WB High Temperature Roller Bearing

AS8112WE and AS8112WB belong to 8112 single direction axial cylindrical roller thrust bearings, unified boundary dimensions d=60mm, D=95mm, T=26mm. The two models differ only in retainer material and structure.

AS series thrust roller bearing consists of shaft washer, housing washer and dense cylindrical roller assemblies. Short cylindrical rollers form line contact with raceway surface, delivering extremely high static and dynamic axial load capacity, ideal for equipment bearing large one-way axial thrust load. The inner shaft washer fits the rotating shaft, outer housing washer matches stationary housing seat, allowing pure axial load transmission with limited radial positioning function.

All washers and cylindrical rollers adopt fully quenched GCr15 bearing steel with ultra-precision mirror grinding raceway, low friction loss and stable anti-fatigue performance. Widely used for vertical lathe spindle, heavy press ram, vertical hydraulic cylinder, mining heavy lifting vertical shaft and heavy-duty reduction equipment.

1. Separable three-piece split structure, shaft washer, roller cage assembly and housing washer can be installed separately, greatly simplify vertical shaft disassembly and maintenance work.
2. Two cage versions for differentiated working condition matching: brass WE cage adapts high-temperature, continuous heavy axial thrust; steel WB cage controls cost for standard general machinery.
3. Dense short cylindrical roller line contact layout, ultra-high axial bearing capacity, excellent resistance to instantaneous impact thrust generated by presses and vertical machine tools.
4. Ultra-smooth superfinished raceway surface, low friction coefficient, effectively restrain temperature rise under long-time continuous axial load rotation, avoid seizure failure.
5. Full integral quenching heat treatment reaches HRC60–65 high hardness, outstanding wear and fatigue resistance, extend overhaul cycle of heavy vertical equipment.
6. Pure one-way axial load design, stable load distribution on all rollers, effectively disperse vertical gravity and pressing thrust of machine tool spindles.
7. Standard metric universal mounting dimension, fully interchangeable with global standard 8112 thrust roller bearings, no modification to existing shaft and housing.
8. Complete customized service: P4/P5 high precision upgrade, OEM laser marking on washer surface, neutral export carton anti-rust packaging, high temperature resistant special grease pre-filling.

Q1: What is the difference between AS8112WE and AS8112WB?
A1: The difference is retainer material. AS8112WE adopts solid machined brass cage, suitable for high temperature and long-time continuous heavy axial load; AS8112WB uses stamped steel cage, cost-saving for general medium-load vertical machinery.
Q2: What load can AS8112 thrust roller bearing bear?
A2: It is single direction thrust bearing, mainly bear large one-way axial load, can only bear tiny incidental radial force, not suitable for equipment with big radial load.
Q3: What is the advantage of three-piece separable structure?
A3: Shaft washer, roller assembly and housing washer can be separated freely, convenient to assemble the shaft and bearing seat respectively, greatly reduce maintenance difficulty of vertical spindle equipment.
