Import Auto Bearing 6306 — Buy in Bulk from Supplier in China

The Auto Bearing 6306 is a deep groove ball bearing with a 30 mm inner diameter, 72 mm outer diameter and 19 mm width, designed for radial and axial load handling in automotive applications. Its single-row design and shielded or sealed variants provide protection against contaminants while maintaining low friction under high-speed rotation. The bearing’s cage material is typically pressed steel or polyamide, ensuring stability at operational temperatures up to 120°C.

Manufactured from high-carbon chromium steel GCr15 or equivalent, the 6306 bearing meets standard ABEC-1 tolerance for most automotive uses, with typical dynamic load ratings around 22 kN and static load ratings near 13 kN. Variants may include C3 or C4 internal clearance for heavy-duty conditions, while standard lubrication uses lithium-based grease for extended service intervals. The design conforms to ISO 15 standards for metric series bearings, ensuring interchangeability across OEM and aftermarket systems.

This bearing is widely used in wheel hubs, transmissions, alternators, and industrial machinery where compact size and moderate load capacity are required. Automotive repair shops and vehicle manufacturers source it for passenger cars, light trucks, and agricultural equipment. Buyers should confirm packaging options, such as boxed sets of 10 or bulk pallets, and verify compliance with application-specific torque and vibration standards before ordering.
