PFI WHEEL BEARING SEALED PW42720038CS 42x72x38mm EACH
PFI PW42720038CS is a double row deep groove ball bearing with contact seals on both sides. It is pre-lubricated with high-performance grease for extended service intervals. The bearing is made of hardened and ground bearing steel, typically AISI 52100 Chrome steel, with a reinforced polyamide or steel cage depending on application requirements. Its dimensions are a bore diameter of 42 mm, outer diameter of 72 mm, and width of 38 mm. It offers an approximate dynamic load rating of 42,000 - 48,000 N and a static load rating of 34,000 - 39,000 N. The limiting speed with grease is up to 7,000 RPM, and the operating temperature range is -30°C to +120°C. This bearing is suitable for automotive wheel hubs, electric motors, gearboxes, transmissions, conveyor systems, agricultural and construction machinery, and industrial pumps and compressors. It provides a compact design, enhanced load capacity, reduced maintenance, high precision, and reliability.
