The 32008 tapered roller bearing is a high-precision heavy-duty mechanical component engineered for large-medium duty machinery operating in harsh and complex conditions. With dimensions of 40mm inner diameter, 68mm outer diameter, and 21mm width, this bearing offers enhanced load-bearing capacity compared to the 32006 model, making it suitable for applications requiring efficient handling of heavy radial loads and moderate-to-high axial forces.
Features larger-sized tapered rollers manufactured from high-carbon chromium bearing steel (GCr15SiMn) with superior hardenability and toughness. Through strict heat treatment, rollers achieve surface hardness of HRC58-64 and core hardness of HRC30-45, ensuring excellent wear and impact resistance.
Both inner and outer rings feature matched tapered raceways with optimized cone angles. The raceways undergo advanced heat-treatment processes including carburizing, quenching, and tempering to form a uniform hardened layer (2-4mm depth) with surface hardness of HRC58-64.
Utilizes high-strength steel cage precision-machined using CNC equipment. Advanced designs feature corrosion-resistant surface treatments or brass cages for high-temperature applications up to 200°C.
Basic rated dynamic load (Cr): 95-105kN
Basic rated static load (C0r): 130-145kN
Axial load capacity: Up to 40% of radial load
Reference speed (grease lubrication): 3800-4800 r/min
Limiting speed (oil-bath lubrication): 5500-6500 r/min
Requires precise installation with radial misalignment ≤0.03mm and axial misalignment ≤0.02mm. Inner ring uses interference fit (H7/p6) with shaft, while outer ring uses clearance fit (H7/js6) with housing.

Use high-quality lithium-based grease (NLGI 3) for general applications, filling 1/3-1/2 of bearing space. For high-temperature environments (150-200°C), use synthetic polyurea-based grease. Lubrication intervals: 2-4 months for normal use, 1 month for harsh conditions.
Monitor vibration levels (normal: ≤2.5mm/s) and bearing temperature. Stop equipment if vibration exceeds 4mm/s or temperature rises above 100°C. Conduct ultrasonic testing every 3 months for critical equipment.
Store in clean, dry environment (5-25°C, humidity ≤50%) in original packaging. Store horizontally with maximum 2-layer stacking. Inspect every 3 months for rust or moisture.
