BS2-2308 K.2RS.VT143 STC spherical roller bearing

STC BS2-2308-K-2RS-VT143 Sealed Spherical Roller Bearing (Tapered Bore)

The STC BS2-2308-K-2RS-VT143 is a technologically advanced rolling unit engineered for trouble-free operation in high-contamination 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) 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, eliminating the risk of damage caused by shaft deflections or housing misalignment.

Application

• Conveyor Systems: Perfect for mines and quarries, where 2RS seals protect raceways from dust and grit.
• Agricultural Machinery: Main shafts of equipment working in direct soil contact and varying weather.
• Industrial Fans: Stable operation in areas with difficult service access due to factory lubrication.
• Wood Industry: Resistance to wood chips and sawdust in sawmills and chippers.
• Heavy Mechanical Drives: Misalignment compensation in large gearboxes and drive shafts.

Technical Specification

• Manufacturer: STC (Specialized Technical Components).
• Designation: BS2-2308-K-2RS-VT143.
• Dimensions: 40 mm (ID) x 90 mm (OD) x 33 mm (Width).
• Bore: Tapered (K) – 1:12 taper ratio.
• Sealing: 2RS (Double-sided contact rubber seals).
• Lubrication: VT143 (Premium factory lithium grease).
• Internal Clearance: CN (Normal) – optimal for standard fitting.

Features and Benefits

• Hermetic Protection (2RS): Effective isolation of the bearing interior drastically extends service life compared to open versions.
• Easy Clearance Adjustment: The tapered bore allows for precise setting of operational clearance via axial displacement on the taper.
• Ready-to-Fit: Lubricated and sealed – eliminates errors related to incorrect grease selection during installation.
• Full Self-Alignment: The bearing operates smoothly even under angular shaft deflection, reducing machine stress.
• Reinforced Design: The BS2 series offers higher dynamic load resistance than standard ball bearings.

Why Choose This Product

By choosing the STC BS2-2308-K-2RS-VT143, you are investing in a "Fit and Forget" solution. In 40 mm shaft applications where dust and moisture shorten the life of regular bearings, this sealed STC spherical model guarantees peace of mind and production continuity. It is the ideal choice for demanding users looking to minimize unplanned downtime and maintenance costs.
