As an authorized distributor and premier supplier in New Delhi, Manglam Sales Corporation supplies genuine Koyo (JTEKT) Deep Groove Ball Bearings - 6030 ZZ C3. Designed for demanding industrial applications requiring high rotational speeds and dynamic heavy-load capacities, this premium Japanese precision bearing features a 150 mm inner diameter, 225 mm outer diameter, and 35 mm width. The ZZ specification indicates dual non-contact metallic side shields that protect against dust, dirt, and contaminants while retaining factory-filled high-performance lubrication. Engineered with C3 internal radial clearance, it comfortably accommodates thermal expansion and shaft misalignment under heavy duty or elevated operating temperatures. Manglam Sales Corporation guarantees 100% original Koyo stock, competitive wholesale pricing, and fast dispatch across New Delhi and the NCR region to ensure uninterrupted power transmission and reduced maintenance downtime for your machinery.
Technical Specifications
Bore Diameter (Inner): 150 mm
Outer Diameter: 225 mm
Width / Thickness: 35 mm
Basic Dynamic Load Rating (C_r): ~125 kN
Basic Static Load Rating (C_{0r}): ~118 kN
Limiting Speed (Grease Lubrication): ~2, 800 RPM
Key Operational Characteristics
C3 Internal Clearance: The internal radial play is greater than standard (Normal/CN clearance). This prevents binding and overheating caused by thermal expansion during high-speed operation or intense heat transfer from the shaft.
Dual Metal Shields (ZZ): Offers low-friction protection against particle intrusion without causing contact resistance, making it ideal for high-speed motor and gearbox applications.
Versatile Load Capacity: Handles high radial loads alongside moderate axial (thrust) loads in both directions due to deep raceway grooves.
Cage Material: Pressed SteelSealing: Dual Metal Shields (ZZ / 2Z)
