Product Introduction
The L853049/L853010 is a large-bore, thin-section inch-series tapered roller bearing engineered for high-diameter shaft applications requiring lightweight, compact radial envelopes. Measuring 276.23 x 352.43 x 36.51 mm, this assembly features an exceptionally wide 276.23mm inner bore relative to its 352.43mm outer diameter. Crafted from vacuum-degassed GCr15 bearing steel, it provides outstanding structural rigidity while allowing equipment manufacturers to maximize hollow shaft sizes or reduce overall housing weight. It is widely specified by global B2B clients in heavy machinery, rotary tables, and industrial gear drives.
Applications
Steel rolling mills and metallurgical equipment.
Large industrial rotary tables and indexing heads.
Heavy-duty mining machinery and hollow-shaft gear reducers.
FAQ
Q: What does the "L" prefix stand for in L853049/L853010?
A: The "L" prefix signifies a "Light" load rating series in imperial bearing nomenclature, optimizing bore size relative to section thickness.
Q: Do you supply material test reports for large industrial bearings?
A: Yes, full Certificates of Analysis (COA) and material heat-number traceability are provided for all heavy industrial orders.
