Product Description
The 352240 double row tapered roller bearing (superseding old Chinese designation 97540E) is a heavy-duty radial bearing with a 200 mm bore, 360 mm outside diameter, and 218 mm total width. Its double-row configuration carries large radial loads and axial loads in both directions, with self-aligning capability that compensates for shaft deflection under shock and misalignment. Nexans Bearing (internal brand NKS) manufactures and stocks this model for rolling mills, gearboxes, mining, and oil-field equipment, and supports OEM/ODM production to customer drawings and samples.

Cross-references are for identification only. Verify dimensions and fit against the OEM catalog before substitution.
The 352240 is specified for equipment where combined radial and bi-directional axial loads dominate:
Rolling mills & steel works — back-up and work-roll stands
Heavy gearboxes & reducers — mining, cement, marine drives
Mining & tunneling machines — conveyors, breakers, excavators
Oil-field & hydraulic machinery — drawworks, mud pumps
Hoisting & cranes — slewing and drum supports
Selection tips: Set clearance/preload to the application; because the bearing handles axial load in both directions, axial end-play must be set at installation. Supplied as a pre-adjusted unit for direct mounting where specified. For corrosive or high-temperature duty, request surface treatment or alternative cage material.
Q: What is the difference between 352240 and 97540E?
A: 97540E is the old GB designation; 352240 is the current GB number for the same 200×360×218 mm double row tapered roller bearing. Both refer to one product.
Q: Can 352240 replace an NSK, NTN, or KOYO unit?
A: Common equivalents include NSK HR200KBE52+L, NTN 432240 / 432240U, KOYO 46T32240JR/174, and NACHI 200KBE22. The cross-reference is for identification—verify dimensions and fit against the OEM catalog before substitution.
Q: What are the load ratings?
A: Dynamic ≈ 2350 kN and static ≈ 4350 kN per standard catalogs. Confirm the exact values against the QC report for your specific lot.
Q: What material and certifications apply?
A: Rings and rollers are chrome steel GCr15 (52100 / SUJ2 equivalent). Each lot is inspected to ISO 492 (dimensions) and ISO 281 (load rating).
Q: What is the lead time and minimum order?
A: In-stock units ship within days; OEM/ODM production typically runs 20–35 days. MOQ is negotiable—contact sales for a quote.
Q: Which clearance and precision grades are available?
A: Clearance C2–C5 (C3 standard) and precision P0–P2 / ABEC 1–9 are available on request.
