SKF Split Spherical Roller Bearings are a special bearing design with the following key features and uses:
Design Features: SKF Split Spherical Roller Bearings feature two rows of symmetrical rollers, a common spherical outer raceway and two inner raceways that are tilted at an angle to the bearing axis. This design enables the bearings to accommodate large radial loads, while also being able to accommodate axial loads in both directions
Application Scenarios: These bearings are suitable for a variety of heavy-duty industries such as mining, mineral processing and cement production. Due to their split design, they are particularly suitable for difficult-to-access applications such as trapped bearing positions in machines, as the split design makes installation, removal and maintenance easier, reducing downtime and maintenance costs
Size Range: SKF Split Spherical Roller Bearings are available in two size ranges: one with a bore diameter from 140 to 200 mm and the other with a bore diameter from 240 to 450 mm. For other sizes, please contact SKF for more information.
Benefits: In the mining industry, SKF’s split spherical roller bearings (SRB) can help reduce maintenance costs and improve safety. For example, 231 series split spherical roller bearings are commonly used in mining conveyor and stacker reclaimer applications. Using split bearings means that the drive coupling and gearbox do not need to be disassembled when replacing the bearings, thus reducing unnecessary costs and downtime.
SKF Split Spherical Roller Bearings are innovative, self-aligning bearings engineered for applications where traditional solid bearings are impractical due to complex assembly, restricted access, or the need for minimal downtime during maintenance. Combining the high load capacity of spherical roller bearings with a split design, these bearings simplify installation, inspection, and replacement in heavy machinery, industrial systems, and large-scale equipment. Their unique construction allows the bearing to be disassembled into two halves, enabling quick servicing without dismantling adjacent components—ideal for industries prioritizing operational efficiency and reduced maintenance costs.
Key Features & Technical Advantages of SKF Split Spherical Roller Bearings
Two-Piece Construction: The bearing is split into upper and lower halves, allowing installation or removal around shafts or in confined spaces without disassembling machinery.
Time-Saving: Reduces downtime by up to 90% compared to solid bearings, critical for industries like mining, energy, and marine.
Precision Alignment: Manufactured to tight tolerances, ensuring seamless reassembly and consistent performance post-maintenance.
Misalignment Compensation: Accommodates ±1.5–2.5° of angular misalignment, mitigating issues caused by shaft deflection, housing inaccuracies, or thermal expansion.
Spherical Raceway Design: Distributes loads evenly across rollers, minimizing edge stresses and extending service life.
Radial and Axial Load Capacity: Engineered to support heavy radial loads and moderate axial loads in both directions, making them versatile for dynamic applications.
Shock Load Resistance: Robust rollers and raceways absorb impact forces in harsh environments (e.g., crushers, vibrating screens).
High-Performance Materials: Components made from case-hardened chromium steel (SAE 52100) with optional coatings (e.g., SKF NoWear®) for enhanced wear and corrosion resistance.
Advanced Cage Designs: Steel or brass cages maintain roller spacing, reduce friction, and withstand high centrifugal forces.
Integrated Lubrication Grooves: Facilitate grease or oil distribution for consistent performance in high-temperature or high-speed applications.
Sealing Solutions: Compatible with SKF’s range of seals (e.g., Labyrinth, V-ring) to exclude contaminants like dust, water, and debris.
Bore Size Range: Available in diameters from 100 mm to 1,000+ mm to suit large shafts in heavy equipment.
Special Configurations: Customizable split housings, lubrication systems, and surface treatments for unique operational needs.
SKF Split Spherical Roller Bearings redefine reliability and efficiency in heavy industrial applications, offering a unique blend of self-alignment, split-design convenience, and unparalleled load capacity. From mining crushers to wind turbine gearboxes, these bearings empower industries to minimize downtime, reduce maintenance costs, and maximize operational uptime. Backed by SKF’s engineering legacy and global support network, they represent a strategic investment in durability, performance, and sustainability. Whether for new installations or retrofitting aging systems, SKF’s split spherical roller bearings deliver a future-proof solution for the world’s most demanding mechanical challenges.
