Spherical Roller Bearings
Aarya Sales supplies high-quality spherical roller bearings (SRBs) designed to handle heavy radial and axial loads while accommodating shaft misalignment. These bearings feature a spherical outer ring raceway with two rows of barrel-shaped rollers, ensuring smooth operation even under challenging conditions.
Spherical Roller Thrust Bearings
Spherical roller bearings are widely used in industries requiring high load capacity, durability, and reliable performance in harsh environments. Their self-aligning design helps compensate for shaft deflection and mounting errors, making them ideal for heavy-duty applications.

Frequently Asked Questions (FAQs)
1. Why is it called a spherical roller bearing?
It is named after its spherical outer ring raceway design, which allows the bearing to accommodate misalignment and handle loads efficiently.
2. Which is better: roller bearing or spherical roller bearing?
The choice depends on the application. Spherical roller bearings are ideal where misalignment and combined loads are present, while other roller bearings are suited for specific load conditions.
3. Where are spherical roller bearings used?
They are used in industries such as mining, construction, steel, power generation, and heavy machinery applications.
4. Can spherical roller bearings handle axial loads?
Yes, these bearings are designed to support both radial and axial loads simultaneously.
5. How to check spherical roller bearing clearance?
Clearance can be measured using a feeler gauge or dial indicator and compared with manufacturer specifications to ensure proper operation.
Spherical Roller Bearing Supplier in India — Aarya Sales
Spherical roller bearings (SRB) are self-aligning bearings capable of handling very heavy combined radial and axial loads while tolerating shaft misalignment up to ±1.5°–2°. This makes them the preferred choice for machinery where shaft deflection or misalignment is unavoidable. Aarya Sales supplies SRB in bore sizes 25 mm to 1250 mm in standard, E-design (enhanced capacity), and sealed variants.
Applications: heavy industrial drives, vibratory screens, crushers, conveyors, fans, centrifugal pumps, gearboxes, paper machinery, cement kilns, and wind turbines. Available with tapered bore (K suffix, 1:12 or 1:30 taper) for mounting on adapter/withdrawal sleeves on plain shafts. Brass (M/MB) and pressed steel cages. Internal clearances C1–C5.
Frequently Asked Questions
A spherical roller bearing has two rows of barrel-shaped rollers running on a common spherical outer ring raceway. This geometry allows the bearing to automatically compensate for shaft misalignment and housing deflection of ±1.5° to ±2°, making it ideal for long shaft applications where perfect alignment is difficult.
Spherical roller bearings are designed for very heavy radial loads combined with axial loads in both directions. The E-design (enhanced capacity) series offers up to 20–25% higher dynamic load ratings than standard SRB of the same size. They outperform cylindrical roller bearings in combined-load scenarios.
A tapered bore bearing (K suffix: e.g., 22318-K) has a 1:12 bore taper (or 1:30 for larger sizes) and is mounted on an adapter sleeve, withdrawal sleeve, or tapered shaft journal. This allows shaft mounting without a precision ground journal and enables easy installation and removal on long or inaccessible shafts.
We supply spherical roller bearings from 25 mm bore to 1250 mm bore in ISO dimension series 22 (21300/22200/22300/23000/23200/24000 series). Split spherical roller bearings for difficult-to-access positions are also available.
Vibratory screens and feeders, jaw and cone crushers, belt and bucket conveyor head/tail pulleys, ball mills and SAG mills, centrifugal fans and blowers, paper and pulp machinery, large gearboxes, cement kiln tyres, and offshore equipment.
Grease lubrication is standard for most applications. Bearings operating above 80°C, at high speeds, or under very heavy loads often use circulating oil lubrication. Solid relubrication fittings (grease nipples) and relube intervals are specified based on speed factor (n·dm) and operating temperature.
