BS2-2205 K.2RS.VT143 STC spherical roller bearing

STC BS2-2205-K-2RS-VT143 Sealed Spherical Roller Bearing (Tapered Bore)

The STC BS2-2205-K-2RS-VT143 is a high-tech rolling unit engineered for faultless operation in the harshest industrial environments. This model features a tapered bore (K) with a 1:12 taper, allowing for precise mounting using an adapter sleeve or directly on a tapered shaft journal. Equipped with contact rubber seals (2RS) made of NBR and factory-filled with the optimal dose of VT143 premium lithium grease, it is completely maintenance-free. As a spherical roller bearing, it offers full self-alignment, compensating for shaft deflections and housing misalignment.

Application

• Conveyors & Transporters: Excellent protection against dust and grit in mining and aggregate plants.
• Agricultural Machinery: Bearing arrangements for shafts exposed to soil contact and moisture.
• Fans & Blowers: Quiet and stable operation in areas with restricted service access.
• Wood Industry: Resistance to wood chips and fine sawdust in sawmills and chippers.
• Drive Systems: Misalignment compensation in mechanisms subjected to high vibrations.
