The 6308 is a deep groove ball bearing from the 6300 series, offered in 2RS rubber sealed, ZZ metal shielded, and OPEN configurations to suit different operational needs. This model features a 40mm bore, 90mm outer diameter, and 23mm width, constructed from chrome steel GCr15, a high carbon chromium bearing steel known for durability and resistance to wear in precision applications. The design supports radial and axial loads, making it a versatile choice for electric motors, general machinery, and industrial equipment requiring stable performance.
Chrome steel GCr15 provides the necessary hardness and fatigue resistance for high-speed operation, while the sealed or shielded variants offer protection against contaminants, extending service life in harsh environments. Typical for the 6300 series, this bearing adheres to standard tolerances and clearance classes defined by ISO 492 and ABEC-1 precision grades, ensuring compatibility with global machinery standards. The OPEN variant allows for easier lubrication access, while the 2RS and ZZ configurations reduce maintenance by retaining grease and blocking debris.
Industrial distributors and OEM buyers source the 6308 for applications in agricultural machinery, conveyors, and power tools where reliable rotation and load handling are critical. The bearing’s low noise and stable quality make it suitable for environments requiring precision and consistency. Buyers typically confirm packaging options, such as boxed or palletized quantities, and verify compliance with application-specific load and speed ratings before bulk orders.

Before ordering, verify the bearing’s configuration (2RS, ZZ, or OPEN) matches your application’s environmental and lubrication requirements. Confirm the precision grade and tolerance class, as these directly impact performance in high-speed or high-precision machinery. Request material test certificates for the chrome steel GCr15 to ensure compliance with industry standards such as AISI 52100 or DIN 100Cr6.
Discuss logistics details such as packaging, which may include individual boxing, inner cartons, or palletized shipments to prevent damage during transit. Clarify the lead time for bulk orders, as this can vary based on stock availability and custom configurations. Incoterms such as FOB Ningbo or CIF destination port should be agreed upon, along with payment terms that may include a 30% deposit and 70% balance before loading.
Inspect the bearings upon receipt for dimensional accuracy, surface finish, and the integrity of seals or shields. Request a copy of the manufacturer’s quality control report, which should include measurements for bore, outer diameter, and width, as well as noise and vibration test results. For critical applications, consider third-party inspection to validate the bearing’s compliance with specified tolerances and performance criteria.
