Import Crossed Roller Bearings — Buy in Bulk from Supplier in China

The crossed roller bearings offered by Frun Industry Co., Ltd. are engineered for high load capacity and compact installation in precision machinery. They feature a crossed‑roller arrangement that distributes loads radially and axially, allowing stable motion under demanding conditions. The bearings are supplied without a specific series designation, but they conform to standard crossed‑roller dimensions ranging from 20 mm to 80 mm bore size. The supplier highlights a basic load capability that meets the needs of robotics and aerospace equipment.

Each bearing is manufactured from high‑carbon chromium steel, typically AISI 52100, and undergoes carburizing heat treatment for surface hardness. The components are usually finished with a polished raceway and are lubricated with high‑temperature grease to ensure low friction. Although the listing does not specify a seal, a standard open design is common, while sealed variants can be requested. The products are produced in accordance with ISO 281 load‑rating standards and ISO 9001 quality‑management practices.

Typical applications include robotic joints, aerospace actuation systems and high‑speed manufacturing equipment where precise positioning is essential. Equipment manufacturers and system integrators often seek flexible order quantities and can choose FOB or CIF shipping from China. The supplier states that packaging is designed for safe bulk transport, but does not disclose exact MOQ, lead time or certification details. Prospective buyers should request the specific dimensional catalogue, seal options and any required test certificates before finalising the purchase.
