Deep Groove Ball Bearing

‌1. Material Composition‌

· ‌Core Materials‌:

· ‌Bearing steel‌ (GCr15 or equivalent) with surface hardness ≥HRC 58 for high wear resistance and fatigue strength

· ‌Cage variants‌: Nylon (PA66) for lightweight applications or brass for extreme shock loads and vibrations

· ‌Surface Treatments‌:

· Super-finished raceways with surface roughness ≤Ra 0.1 μm to minimize friction and noise

· Optional corrosion-resistant coatings (e.g., zinc plating) for harsh environments

‌2. Structural Design‌

· ‌Configuration‌:

· Single-row design with uninterrupted raceways for pure radial load support and limited axial load capacity

· Shielded (ZZ) or sealed (2RS) variants to prevent contamination in dusty or humid conditions

· ‌Dimensions‌:

· Standard bore sizes from 3 mm to 400 mm, compliant with ISO 15:2017 dimensional standards

· Snap ring grooves (e.g., Model 6800 series) for simplified axial fixation in compact assemblies

‌3. Manufacturing Processes‌

00001. ‌Heat Treatment‌:

· Carburizing or induction hardening to achieve uniform core toughness and surface hardness

00002. ‌Precision Grinding‌:

· CNC grinding of inner/outer rings to tolerance class ABEC-3 or higher (ISO P0/P6)

00003. ‌Assembly‌:

· Automated insertion of ceramic or steel balls with ±0.002 mm diameter consistency

‌4. Performance Parameters‌

‌5. Industrial Applications‌

· ‌Automotive‌:

· Wheel hubs and electric bicycle motors (e.g., NSK 6004 series with sealed designs)

· ‌Industrial Machinery‌:

· Conveyor systems and agricultural equipment (e.g., Timken brass-cage bearings for high-vibration environments)

· ‌Consumer Appliances‌:

· Low-noise shielded bearings for HVAC fans and household appliances
