The SL1923 and NJG series are cageless full complement cylindrical roller bearings.

They are capable of withstanding axial loads acting on the inner ring flange. All rollers are securely fixed within the outer ring and will not detach even when the inner ring is removed, facilitating individual installation and removal.

These bearings feature high radial load capacity, excellent shock resistance, and high rigidity, and are widely used in gearboxes, metallurgical machinery, rolling mills, mining equipment, crushers, construction machinery, papermaking machinery, extrusion equipment, conveyor systems, and other heavy industrial transmission devices.

Structural Characteristics: The Dual Advantages of Full-Complement Rollers and an Spherical Outer Ring Design

The core design of spherical outer ring, full-complement cylindrical roller bearings incorporates two major innovations: a full-complement roller structure and a spherical self-aligning function.

1. Full-Complement Roller Design: Unlike traditional bearings that utilize a cage, the SL05/06 series eliminates the cage to fill the raceway entirely with cylindrical rollers, thereby increasing the roller count by approximately 20% to 30%. This design significantly enhances the bearing's radial load capacity, making it particularly suitable for applications involving high impact and vibration—such as mining machinery and port cranes.

2. Spherical Self-Aligning Function: The bearing's outer ring features a spherical design that mates with a spherical housing seat, automatically compensating for misalignment between the shaft and the housing bore (typically allowing for an angular error of ≤2°). This feature effectively reduces the precision requirements for installation and accommodates shaft deflection under dynamic operating conditions, thereby extending the service life of the equipment.

The SL1822.. /NCF22.. series bearings are single-row full complement cylindrical roller bearings, belonging to the semi-locating bearing series.

The full complement design, without a cage, makes them suitable for handling large radial and impact loads.

The inner ring typically has two ribs, and the outer ring has one rib. This allows the bearing to axially position the shaft in one direction and withstand axial forces in that direction, while allowing axial displacement in the opposite direction.

Due to their high load and low speed characteristics, the SL1822 series bearings are widely used in:

Construction machinery: such as gearboxes and hoisting machinery.

Heavy industry: metallurgical equipment, mining machinery, and conveying systems.

Transportation: rotating components of ships and vehicles.

SL01 48 Series,SL01 49 Series Cylindrical roller bearings are Locating Double Rows Full Complement Cylindrical Roller Bearings

Semi-Locating Double Rows Full Complement Cylindrical Roller Bearings

Full complement cylindrical roller bearings can be used in mining machinery and equipment. Mining machinery is machinery directly used for operations such as mineral mining and screening. Including mining machinery and mineral processing machinery. The working principles and structures of prospecting machinery are mostly the same or similar to the mining machinery used to mine similar minerals. Broadly speaking, prospecting machinery also belongs to mining machinery. In addition, a large number of cranes, conveyors, ventilators and drainage machinery are also used in mining operations.

With Sealed Double Row Full Complement Cylindrical Roller Bearings-With Snap Ring Grooves

This series of bearings are mainly used in pulley equipments and are widely used in port machinery and construction machinery fields.

The SL05 and SL06 series bearings, with their performance advantages, are widely used in the following fields,

Selection Rule: Select SL05 for the fixed end and SL06 for the floating end. They must be used in pairs and cannot be interchanged or used alone.

Working Condition Matching: For shafts requiring axial locking and bearing axial force, select SL05; For shafts with long lengths, large temperature differences, and requiring compensation for thermal expansion, select SL06.

1. Heavy industrial equipment: such as metallurgical rolling mills and mining crushers, which need to withstand radial loads of several tons to tens of tons. Models like the SL05016 (80mm inner diameter, 45mm width) ensure stability under high loads through a full complement roller structure.

2. Engineering transportation equipment: including conveyor belt systems and excavator slewing bearings. The spherical self-aligning function can cope with vibrations and impacts during vehicle operation. For example, the SL06016 (80mm inner diameter, 34mm width) provides a high-load-bearing solution in compact spaces.

3. Agricultural and material handling machinery: in equipment such as combine harvester drive shafts and vibrating screens, the sealing performance and anti-contamination capabilities of the bearings further reduce maintenance frequency and adapt to dusty and humid environments.

As global carbon neutrality goals advance, bearing energy efficiency has become a key focus. In the future, the SL series may reduce frictional losses through lightweight designs (such as hollow rollers) or by employing biodegradable lubricants to reduce environmental burden. Furthermore, remanufacturing technology will drive the reprocessing and recycling of old bearings, further reducing industrial costs.

The SL05 and SL06 series spherical full complement cylindrical roller bearings continue to empower the efficient operation of industrial equipment through technological innovation. From heavy machinery to precision transmissions, their high reliability and adaptability are redefining the possibilities of industrial transmission. For equipment manufacturers, a deep understanding of bearing characteristics and appropriate selection will be a crucial step in enhancing equipment competitiveness.
