358/354 Single Row Imperial Tapered Roller Bearing 45×85×20.638mm Stamped Steel Cage Auto Axle

1. Product Overview

The 358/354 is single-row imperial tapered roller bearing, composed of separable cone (inner ring 358) and cup (outer ring 354) with stamped steel cage. It features 11.5° contact angle to bear combined heavy radial and one-way axial loads, linear contact between rollers and raceway delivers strong load capacity and low friction. Separable inner and outer rings simplify installation, disassembly and preload adjustment during assembly. Widely used for light truck wheel hubs, agricultural machinery drive axles, construction equipment reducers and general industrial transmission systems under medium-speed heavy shock load.

2. Technical Specifications

Complete metric & imperial dimensional drawings and load data are available upon customer request.

3. Key Advantages

• Separable cone and cup independent design enables easy mounting, disassembly and precise preload pairing in back-to-back or face-to-face arrangement
• Optimized logarithmic roller profile reduces edge stress, stable performance under impact and heavy alternating load, extending service life
• 11.5° moderate contact angle balances radial and one-way axial bearing capacity, adapts to axle and reducer transmission working conditions
• Stamped steel lightweight cage with stable guidance, low running torque and good heat dissipation for continuous medium-speed operation
• Imperial standard dimension fully interchangeable with mainstream international brand counterparts, convenient aftermarket replacement
• Customizable options include special anti-rust treatment, high-temperature grease, OEM laser marking and matched bearing sets

Effectively improve equipment transmission rigidity and reduce frequent maintenance downtime
