SAE 52100 Grade Steel
Manufactured from ultra-clean high-carbon chromium steel (100Cr6), hardened to 60-64 HRC for exceptional fatigue life and resistance to subsurface cracking.
In-House QC & Testing Labs
100% pre-dispatch quality verification performed at our dedicated in-house testing laboratories by qualified QC engineers for dimensional runout, radial clearance, and noise testing.
Precision Class (P0 / P6 / P5)
Standard ABEC-1 (ISO Normal / P0) tolerance with optional P6/P5 precision grades for ultra-low vibration (V2/V3) and high rotational accuracy.
Thermal Stabilization
Dimensionally stabilized for continuous operating temperatures from -30°C to +120°C (standard), with high-temperature synthetic grease available up to +180°C.
Radial Clearance (CN / C3)
Available in Standard Normal Clearance (CN) for steady ambient operating environments or C3 Greater Clearance for thermal expansion.
Global Export & Trade Fairs
Export packaging ready for international supply via Nhava Sheva (JNPT) & Mumbai Air Cargo with upcoming planned participation in premier international trade expos.
Contact Angles (40° B vs 25° AC vs 15° C)
Contact angles define performance: 40° (Suffix B) for maximum axial thrust rigidity; 25° (Suffix AC) and 15° (Suffix C) for ultra-high-speed machine tool spindles.
Duplex Preloaded Pairs (DB / DF / DT)
Universally matchable sets arranged Back-to-Back (DB) for high moment rigidity, Face-to-Face (DF) for housing misalignment, or Tandem (DT) for doubled thrust.
Super-Precision Classes (P5 / P4)
Manufactured to tight dimensional tolerances with ultra-smooth superfinished raceways for minimal thermal growth in CNC spindle assemblies.
Machined Brass & Polyamide Cages
Available with ball-guided machined brass cages (M/MA) or lightweight reinforced polyamide cages (TVP) for low centrifugal forces at high RPM.
