Spherical Roller Bearing BS2-2214-2CS Sealed Double Row 70×125×38mm for Mining and Metallurgical Machinery

Spherical Roller Bearing BS2-2214-2CS Sealed Double Row 70×125×38mm for Mining and Metallurgical Machinery

Product Overview
The Spherical Roller Bearing BS2-2214-2CS is designed for heavy-duty industrial applications, offering exceptional radial load capacity and excellent misalignment compensation.
It features high-efficiency integral contact seals on both sides to ensure clean lubrication and stable running in the most challenging industrial environments.

• Premium Double-Lip Rubber Seals (-2CS): The heavy-duty black NBR contact seals effectively lock premium grease inside while keeping harsh dust, mud, and water completely out.
• High Load Capacity for Demanding Applications: Robust dual-row roller structure handles extreme radial and bidirectional axial loads under high stress.
• Self-Aligning Stability and Precision: Spherical outer ring raceway seamlessly tolerates shaft deflections and angular misalignments without friction spikes.
• Integrated Lubrication Feature: Precision-engineered annular groove and lubrication holes on the outer ring allow effortless relubrication for continuous heavy-load operations.
• Clear Laser Identification Marking: Clear, durable model engraving on the inner ring side ensures authentic tracking and easy replacement during maintenance.

• Mining & Quarrying Equipment: Vibrating screens, heavy-duty crushers, and bulk material handling lines.
• Metallurgical Industry: Continuous casting systems, steel mill conveyor rollers, and processing plants.
• Bulk Conveyor Systems: Long-distance industrial belt conveyors, port loading systems, and large gearboxes.

FAQ

Q1: Can you provide custom bearings?Yes, we support OEM and custom production based on your drawings, specific clearances, or working requirements.

Q2: What is your delivery time?Standard models: 7–15 days from stock. Custom products: 30-45 days depending on specifications.

Q3: Do you support bulk orders?Yes, we provide wholesale pricing structures and stable supply chains for long-term business cooperation.

Q4: What is the operating temperature limit for the BS2-2214-2CS bearing?Due to the built-in NBR (Nitrile Rubber) seals and factory grease, the standard operating temperature range is -30°C to +110°C. For higher temperature environments, we can customize Viton (FKM) seals and high-temp grease.

Q5: Does this sealed bearing ever require relubrication?The bearing is factory-filled with the optimum amount of premium grease and is technically maintenance-free under normal conditions. However, for extremely harsh or continuous heavy-load operations, it features an outer ring groove and lubrication holes to support regular relubrication.

Q6: How much angular misalignment can the BS2-2214-2CS bearing accommodate?Under normal operating conditions, this spherical roller bearing can accommodate angular misalignment of up to 0.5° between the inner and outer rings without affecting its sealing performance or running temperature.
