Import H3128 — Buy in Bulk from Supplier in China

The H3128 is a precision bearing supplied by Tianjin Bifusi Bearings Co., Ltd, featuring an inner diameter of 125 mm, outer diameter of 140 mm and a width of 180 mm. The bore dimensions include B1 97 mm, B2 22 mm and B4 24 mm, and the adapter sleeve assembly weighs 4.1 kg. The package includes a lock nut marked KM 28, a locking device MB 28 and an associated hydraulic nut model HMV 28 E. These dimensions and components are taken directly from the supplier’s product description.

The bearing is machined from high‑carbon chromium steel, a material commonly used for load‑carrying rotary components. Tianjin Bifusi follows the ISO C3 tolerance class, which provides a tight clearance suitable for high‑speed applications. Grease of NLGI 2 grade is typically recommended to ensure reliable lubrication under varying loads. The design aligns with standard industry practices for automotive and industrial gearboxes, offering a balance of strength and fatigue resistance.

This product is targeted at manufacturers of heavy‑duty machinery, gear‑box assemblers and equipment importers requiring robust rotary support. Buyers often integrate the H3128 into transmission systems where dimensional accuracy and load capacity are critical. Trade terms, including incoterms and payment methods, should be negotiated directly with the supplier, as the listing does not disclose specific conditions.
