As a premier distributor and industrial bearing supplier across Uttarakhand, Manglam Sales Corporation supplies genuine Koyo (JTEKT) 1205K C3 Self-Aligning Ball Bearings. Engineered specifically for applications prone to shaft deflection or mounting misalignment, this Japanese precision bearing features a 25 mm tapered bore (1:12 taper), a 52 mm outer diameter, and a 15 mm width. The tapered bore (K) allows for easy installation using an adapter sleeve (e.g., H205) or direct mounting on tapered shaft journals, providing a secure, vibration-resistant fit. Equipped with two rows of balls running on a shared spherical outer ring raceway, it automatically corrects angular misalignment without increasing friction or heat. Featuring C3 internal radial clearance, it comfortably accommodates thermal expansion during high-speed continuous operation. Serving Uttarakhand’s thriving manufacturing hubs—including pharmaceuticals, automotives, food processing, and heavy machinery—Manglam Sales Corporation guarantees authentic Koyo stock, competitive pricing, and fast dispatch across key industrial estates in Haridwar, Pantnagar, Rudrapur, Dehradun, and Roorkee.
Technical Specifications
Bore Diameter (Inner): 25 mm (Tapered bore 1:12, designated by K)
Outer Diameter: 52 mm
Width / Thickness: 15 mm
Bearing Type: Double-Row Self-Aligning Ball Bearing
Internal Clearance: C3 (Greater than standard radial play)
Cage Material: Pressed Steel / Polyamide
Mounting Compatibility: Mounts directly on tapered shaft seats or using standard adapter sleeves (H205 series)
Key Operational Characteristics
Self-Aligning Capability: Accommodates static and dynamic angular misalignment up to 2.5° caused by shaft deflection under load or housing mounting errors, preventing edge stress and premature wear.
Low Operating Friction & Heat: Generates minimal friction compared to other self-aligning bearing designs, enabling smooth, cool running at higher operating speeds.
Tapered Bore Flexibility (K): Simplifies axial position adjustment, preloading, and mounting/dismounting when used in conjunction with adapter sleeves on smooth shafts.
C3 Radial Clearance: Compensates for thermal expansion during continuous operation, ensuring the bearing maintains proper clearance without binding.
Primary Applications in Uttarakhand’s Industrial Zones
High-speed industrial blowers, exhaust fans, and HVAC systems
Textile machinery, high-speed spindles, and spinning frames
Pharmaceutical manufacturing rollers and conveyor drives
FMCG packaging machinery and agricultural processing units
Paper mills and wood processing machinery
