Premier distributor and industrial bearing supplier across Tamil Nadu, Manglam Sales Corporation supplies genuine Koyo (JTEKT) 22238 R Spherical Roller Bearings. Precision-engineered in Japan to perform under severe dynamic loading, heavy vibrations, and shaft deflections, this large-bore spherical roller bearing features a 190 mm inner diameter (bore), 340 mm outer diameter, and 92 mm width. The R designation indicates an enhanced internal construction with optimized asymmetrical spherical rollers, high dynamic load capacity, and superior roller guidance. Equipped with a shared spherical outer ring raceway, it delivers self-aligning capabilities to correct angular misalignments automatically without generating excess friction or operational heat. Tailored to support Tamil Nadu’s diverse industrial landscape—including textile mills, paper plants, wind energy generation, automotive manufacturing, steel production, and port facilities—Manglam Sales Corporation guarantees 100% authentic Koyo products, competitive wholesale pricing, complete batch documentation, and fast dispatch across key industrial hubs including Chennai, Coimbatore, Tiruppur, Madurai, Salem, Hosur, and Thoothukudi.

Key Operational Characteristics
Self-Aligning Capability: Accommodates housing misalignment and shaft deflections up to 1.5°–2.5° without concentrating localized stresses on rolling elements or raceways.
Exceptional Heavy Load Capacity: Dual-row spherical roller layout absorbs massive radial forces combined with heavy bidirectional axial thrust.
Optimized Roller Guidance (R Design): Internal geometry ensures smooth roller motion, reduced friction torque, and minimal heat buildup during continuous 24/7 duty cycles.
Integrated Lubrication Features: Features outer ring annular oil grooves and lubrication holes to simplify grease or oil re-lubrication in heavy industrial machinery.
