3307 B.2RS1 Double Row Angular Contact Ball Bearing, 40° Contact Angle & Dual 2RS1 Double Lip Seals

1. Product Overview

3307 B.2RS1 is a wide-width double-row angular contact ball bearing built with 40° large contact angle and double-sided 2RS1 contact lip seals. Its reinforced double-ball back-to-back internal layout delivers far stronger radial and bidirectional axial load capacity than 32 series models, and effectively resists heavy tilting moments under eccentric working loads. Dual rubber lip seals isolate dust, mud and coolant, with factory pre-filled high-temperature grease for long-term continuous operation, widely matched to heavy farm tillage machines, mine light conveyors and medium industrial gear reducers.

2. Key Advantages

• 40° ultra-wide contact angle greatly boosts axial load bearing performance, ideal for heavy thrust load conditions
• 2RS1 double lip contact seals form tight isolation against abrasive dust, mud and water splashes, locking internal lubricant steadily
• Wide 34.9mm overall width strengthens structural rigidity to withstand large offset tilting moments
• Glass fiber reinforced polyamide cage reduces rotation friction and maintains stable medium-high speed operation
• Integrated double-row one-piece structure eliminates complicated paired installation of two single-row bearings
• Standard ISO dimensional specifications enable direct interchange and replacement of equivalent bearing models

Helps reduce maintenance cost and improve machine performance

3. Applications

This bearing is widely used in:

• Heavy-duty agricultural rotary tillage and harrow equipment shafts
• Mining auxiliary light conveyor heavy roller support assemblies
• Medium-sized heavy-load speed reducer output supporting positions
