3206 B.2RS1 Double Row Angular Contact Ball Bearing, 40° Contact Angle & Dual 2RS1 Lip Seals

3206 B.2RS1 is an integrated double-row angular contact ball bearing equipped with a large 40° contact angle and double-sided 2RS1 lip contact seals. Its internal back-to-back ball layout can simultaneously bear heavy radial loads, bidirectional axial loads and strong tilting moments. Double rubber lip seals block dust, mud and cooling liquid, while factory pre-filled grease lowers maintenance frequency. It is widely fitted on disc harrows, heavy conveyor rollers and medium-duty gear reducers with harsh working environments.

• 40° wide contact angle provides far higher axial load capacity than standard 30° A-type bearings
• 2RS1 dual lip contact seals effectively isolate abrasive dust and water splashes, locking internal lubricant steadily
• Integrated double-row design saves axial installation space compared with two separate single-row paired bearings
• Glass fiber reinforced polyamide cage ensures low friction and stable rotation under medium-high continuous speed
• Pre-lubricated sealed structure avoids frequent on-site re-greasing work
• Standard ISO dimensional specifications support direct interchange and replacement of matching bearing models

This bearing is widely used in:

• Agricultural disc harrow and tillage equipment rotary shafts
• Heavy-duty industrial conveyor roller support assemblies
• Medium-size speed reducer output supporting positions
