Import 6pk 8pk Epdm Transmission Fan Belt/Pk Belt — Buy in wholesale FOB from Supplier in China

The 6pk and 8pk EPDM transmission fan belts from Hebei Boshuo Auto Tech Co., Ltd. are engineered for compact pulley systems and high-speed applications, with a thin body design that maintains flexibility while reducing vibration and heat buildup. These PK belts achieve belt speeds up to 40 m/s, making them suitable for automotive fan and accessory drives where smooth operation and minimal elongation are critical. The EPDM rubber compound provides resistance to heat, oil, and wear, extending service life in demanding environments.

PK belts, or multi-ribbed V-belts, feature longitudinal ribs that increase the contact surface area with pulley grooves, improving power transmission efficiency compared to conventional V-belts. The 6pk and 8pk designations refer to the number of ribs (6 or 8), with the belt width and rib profile optimized for specific torque and load requirements. EPDM is a standard material for such belts due to its durability across a typical temperature range of -30°C to +120°C, though the supplier’s stated range of -50°C to +120°C suggests enhanced thermal stability. The thin profile allows for use with smaller pulleys without sacrificing performance.

These belts are commonly used in automotive cooling systems, alternators, power steering, and air conditioning compressors, where compactness and reliability are essential. Industrial buyers source them for machinery requiring precise, high-speed power transmission with low maintenance. For bulk orders, confirm packaging options, as PK belts are typically supplied in coiled or cut lengths, and verify compatibility with the intended pulley system dimensions and groove profiles.

Hebei Boshuo Auto Tech Co., Ltd. operates from Xingtai, Hebei Province, China, with its office located at Room 2301, Block A, No. 10 Tangning, Quannan East Street, Qiaodong District. The company is categorized under the 'harbor' trust tier, indicating a baseline level of verification for its profile and operations. While the response rate and average response time are currently listed as zero, this may reflect recent updates or temporary unavailability rather than a permanent lack of engagement.

The supplier specializes in automotive components, with a focus on transmission and drive systems. Its product line includes PK belts designed for high-speed and compact applications, leveraging EPDM compounds for durability. The company’s profile does not provide additional details on production capacity, certifications, or export history, so buyers are advised to request these directly for a complete assessment.
