BS2-2312 .2RS.VT143 STC spherical roller bearing

STC BS2-2312-2RS-VT143 Sealed Spherical Roller Bearing

The STC BS2-2312-2RS-VT143 is an advanced, double-row rolling unit engineered for high-contamination industrial environments. The defining feature of this model is the contact seals (2RS), which provide a robust barrier against dust, dirt, and moisture while preventing lubricant leakage. The VT143 suffix confirms that the bearing is factory-filled with the optimal amount of high-grade lithium grease, making it ready-to-fit and virtually maintenance-free. Thanks to its barrel-shaped rollers, this model offers full self-alignment, compensating for shaft-to-housing misalignment.

Application

• Conveyor Systems: Exceptional resistance to dust in mines, quarries, and cement plants due to 2RS protection.
• Agricultural Machinery: Shaft support in machines exposed to soil contact and varying weather conditions.
• Industrial Fans: Ensuring long operation without the need for frequent relubrication in hard-to-reach areas.
• Food & Processing Industry: Machinery requiring high cleanliness and protection against lubricant contamination.
• Lifting Equipment: Winches and crane mechanisms operating in demanding outdoor conditions.

Technical Specification
