Split Bearings

Split bearings are designed with all major components split into halves, allowing them to be assembled around the shaft and fixed together with bolts to form a complete bearing unit. These bearings typically consist of a split inner ring, split outer ring, split cage with rolling elements, fastening rings or clamping rings, fixing bolts, seals, and a lubrication system. They are designed to be installed or removed without dismantling the shaft or surrounding equipment, helping reduce maintenance time, downtime, and installation difficulty.
As a split bearing manufacturer with many years of experience and ISO 9001 certification, BKZ Industry can offer different types of split bearings, including split pillow block bearings, split cylindrical roller bearings, split spherical roller bearings, split tapered roller bearings, split plain bearings, and split thin section bearings. These bearings are widely used in mining, cement, steel, marine, and other heavy-duty industries.

Split Bearings Are Designed With Special Features

Features and Benefits of Split Bearings

Split bearings are designed with special features such as split inner and outer rings, a split rolling element and cage assembly, a bolt fastening system, and a cartridge housing design.

Features of Split Bearings

Split Structure

Split bearings are designed with split bearing components, such as split inner ring, split outer ring, split cage with rolling elements, fastening or clamping rings, fixing bolts, seals, split housing or cartridge unit, and a lubrication system.

High Radial Load Capacity

Most split bearings use roller elements instead of balls, providing line contact that allows them to carry higher radial loads.

Available for Axial and Combined Loads

Some split bearings are designed with angular contact or tapered raceways, which allow them to support axial loads and combined radial and axial loads.

Self-aligning Housing Seat

With self-aligning housing seats, split bearings can accommodate shaft misalignment and minor installation errors.

Pre-set Clearance

Pre-set clearance in split bearings is achieved through precision machining, matched bearing halves, and controlled bolt tightening, so the correct internal clearance can be obtained during installation.

Benefits of Split Bearings

Reduced Downtime

Their split design allows easier installation, faster replacement, and simplified maintenance, which helps reduce equipment downtime.

Easy installation and Replacement

The split structure, modular components, and clamp assembly design allow installation and replacement without removing the shaft.

Lower Maintenance Cost

Split bearings can be installed and removed without dismantling the shaft or surrounding equipment, significantly reducing downtime, labor cost, and maintenance time.

Improved Safety

Split bearings improve maintenance safety by reducing heavy disassembly work, lifting operations, and other potentially hazardous maintenance procedures.

Ideal for Long Shafts, Trapped Positions, Heavy Industries

Split bearings are ideal for long shafts and trapped positions because they can be installed and removed without dismantling adjacent components. They are widely used in heavy industries such as mining, cement, steel, marine, power plants, pulp and paper, and bulk material handling.

Split Bearing Types

Split bearings are classified into different types based on bearing design and load capacity, including cylindrical roller, spherical roller, tapered roller, pillow block units, plain bearings, and thin section bearings. Each type is designed for specific load conditions, shaft sizes, and industrial applications.

Split Cylindrical Roller Bearings

Split Cylindrical Roller Bearings

Split cylindrical roller bearings use split rings with cylindrical rollers and a split cage, providing line contact for very high radial load capacity and high rigidity. They are mainly designed for heavy radial loads rather than axial loads. These bearings are commonly used in conveyors, large fans, marine shafts, and heavy industrial machinery where high radial load capacity is required.

Split Spherical Roller Bearings 2

Split Spherical Roller Bearings

Split spherical roller bearings feature two rows of barrel rollers and a spherical outer raceway, allowing the bearing to accommodate shaft misalignment while carrying heavy radial and axial loads. They are especially suitable for applications with shaft deflection or alignment errors, such as mining equipment, crushers, vibrating screens, and cement machinery.

Split Tapered Roller Bearings 2

Split Tapered Roller Bearings

Split tapered roller bearings use tapered rollers and tapered raceways, allowing them to support combined radial and axial loads and provide accurate shaft positioning. They are typically used in gearboxes, steel mills, marine propulsion shafts, and heavy transmission equipment where both load capacity and shaft positioning are important.

Split Pillow Block Bearings

Split Pillow Block Bearings

Split pillow block bearings consist of a split bearing mounted in a split housing unit, making installation and maintenance easier for large shafts. They are mainly used as mounted bearing units in conveyors, industrial fans, processing equipment, and bulk material handling systems.

Split Plain Bearings

Split Plain Bearings (Split Bushings)

Split plain bearings are sliding bearings made of split bushings, suitable for very large shaft diameters, heavy loads, and low-speed applications. They are commonly used in turbines, generators, compressors, and marine equipment where rolling bearings may not be suitable.

Split Thin Section Bearings

Split Thin Section Bearings

Split thin section bearings have a constant cross-section and very thin ring design, making them suitable for large diameter applications where space and weight are limited. They are commonly used in rotary tables, radar systems, aerospace equipment, and precision positioning machinery.

Split Bearing Size Chart

Split bearings do not have a unified ISO dimension series like standard rolling bearings. Their dimensions are usually manufacturer-specific, but load ratings, tolerances, and fits often follow ISO standards. Therefore, here we list some split bearing sizes that we have supplied for other customers. For your requirements, please contact us directly with your bearing requirements.

Split Bearing Applications

Split bearings are widely used in heavy industrial equipment because they allow easy installation and removal without disassembling the shaft or surrounding components.

FAQs About Thin Section Bearings

Q1. What is a Cooper split bearing?

A Cooper split bearing is is a type of split roller bearing designed by SKF with split inner ring, outer ring, cage, and housing, allowing installation around the shaft without removing surrounding equipment. It is mainly used in heavy industrial machinery such as conveyors, marine shafts, fans, and mining equipment where maintenance access is limited.

Split bearings are mainly used in large industrial equipment where shafts are difficult to remove or equipment downtime must be minimized. Typical applications include conveyors, crushers, large fans, marine propulsion shafts, steel mills, power plants, and bulk material handling equipment.

A split bearing looks like a standard bearing that has been divided into two halves. The inner ring, outer ring, cage, and housing are split and assembled around the shaft, then fixed together with bolts to form a complete bearing unit.

The main difference is installation. Solid bearings must be installed from the shaft end, while split bearings can be assembled directly around the shaft. Split bearings reduce maintenance time and downtime, while solid bearings are usually smaller, cheaper, and used in standard applications.

A split bearing is usually supported by a split housing or pillow block housing. The housing supports the outer ring and carries the load, while the shaft supports the inner ring. The housing also helps maintain alignment and lubrication.
