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.

NU Design (Non-Locating)

Double integral ribs on outer ring and ribless inner ring. Accommodates axial shaft displacement relative to housing caused by thermal elongation.

NJ Design (One-Direction Locating)

Double integral ribs on outer ring and single rib on inner ring. Provides heavy radial support and single-direction axial locating.

NUP Design (Two-Direction Locating)

Double integral ribs on outer ring, single rib on inner ring, plus loose thrust collar. Locates shaft axially in both directions.

Machined Brass Cage (M / EMA)

Heavy-duty roller-guided or ring-guided solid brass cage designed for severe shock loads, heavy vibrations, and high acceleration.
