Roller Bearings Supplier
About Roller Bearing
Roller Bearings are precision-engineered components designed to carry heavy loads while minimizing friction between rotating parts. Unlike ball bearings that use spherical rolling elements, roller bearings use cylindrical, tapered, or spherical rollers to distribute loads over a larger surface area. This results in higher load-carrying capacity, durability, and operational stability. Rohit International is a trusted Roller Bearings supplier across Kolkata, West Bengal, Odisha, Bihar, Chhattisgarh, and Jharkhand, offering a complete range of high-quality bearings designed for industrial, automotive, and engineering applications.
Key Features of Roller Bearings
- High Load Capacity: Suitable for both radial and axial loads depending on bearing design.
- Low Friction & Heat Generation: Ensures smooth and efficient operation.
- Long Service Life: Designed with premium materials and precise heat treatment.
- Durable Design: Resistant to wear, shock, and vibration.
- Wide Range of Configurations: Available in different shapes and sizes for specific applications.
- High-Speed Performance: Precision-engineered cages and rollers for stable operation at various speeds.
- Ease of Maintenance: Designed for simple assembly, lubrication, and replacement.
Types of Roller Bearings Available
Crossed Roller Bearings
- Designed with cylindrical rollers arranged at right angles in a V-shaped groove.
- Provide high rigidity and can handle loads in all directions (radial, axial, and moment loads).
- Ideal for robotics, machine tools, and precision rotary tables.
Cylindrical Roller Bearings
- Use cylindrical rollers for line contact, offering high radial load capacity.
- Suitable for high-speed applications where axial load is minimal.
- Commonly used in electric motors, gearboxes, and turbines.
Taper Roller Bearings
- Have tapered inner and outer ring raceways with tapered rollers.
- Handle combined radial and axial loads efficiently.
- Used in automotive hubs, gearboxes, and heavy machinery.
Precision Taper Roller Bearings
- Manufactured with tight tolerances for high-speed and precision applications.
- Offer low friction, smooth rotation, and extended service life.
- Used in CNC spindles, precision gearboxes, and aerospace systems.
Multiple Row Cylindrical Roller Bearings
- Composed of several rows of rollers for enhanced load capacity.
- Suitable for applications requiring high stiffness and heavy radial loads.
- Common in rolling mills and large gear drives.
Thrust Roller Bearings
- Designed to support heavy axial loads in one direction.
- Provide stable operation under high thrust conditions.
- Found in cranes, presses, and marine equipment.
Two-Row Cylindrical Roller Bearings
- Dual-row design provides higher radial load capacity and rigidity.
- Suitable for high-speed, heavy-duty applications like machine tools and electric motors.
Four-Row Cylindrical Roller Bearings
- Engineered for extremely heavy radial loads and impact conditions.
- Commonly used in rolling mills, steel plants, and heavy industrial applications.
Self Aligning Thrust Roller Bearing
- Combines self-aligning capability with thrust load handling.
- Ideal for applications where shaft misalignment may occur.
- Common in marine propulsion and heavy construction equipment.
Spherical Roller Units
- Incorporate spherical rollers with self-aligning capability for both radial and axial loads.
- Excellent shock load resistance and misalignment compensation.
- Used in mining, cement, and material handling industries.
