SKF Cooper 01B280MMEX bearing split bearing SNL replaces SKF split bearing in the UK

Split cylindrical roller bearing (Cooper)
This is the core product of SKF Cooper and the most mainstream type of split bearing on the market. It usually does not exist separately, but is provided as a complete bearing unit together with the matching bearing seat. According to size and load-bearing capacity, it can be divided into the following main series:

Series Example Features and Positioning Axis Diameter Range (mm)
The 100 series COP.01EB90MEX (EX type) is lightweight, compact, and suitable for high-speed applications.     20 - 90
02 series COP.02B, 02B300 medium, one of the most commonly used standard series, widely used.     15 - 200
01 series COP.01B medium-sized, similar to 02 series, widely used.     15 - 160
03 series COP.03B, 03Bxxx heavy-duty series, suitable for impact and vibration conditions.     40 - 280
The 03E series COP.03EB extreme load series further enhances its load-bearing capacity.     40 - 280
Model example interpretation: Taking COP.01EB90MEX as an example:

COP.: SKF Cooper split bearing.

01: Serial number.

E: EX type allows the bearing to move axially on the shaft (floating end).

B: Brass retainer.

90: Suitable for shaft diameter of 90mm.

MEX: Specific configuration details (such as sealing method, etc.).

⚖️  Split spherical roller bearing (BS2B)
This type of bearing is specially designed for ultra large shaft diameters and heavy load conditions. Its model is usually independent and needs to be used in conjunction with a dedicated split bearing seat.

Interpretation of Model Example:
Taking BS2B 243487 A as an example:

The inner diameter is 1120 mm.

Outer diameter 1540 mm.

Thickness 525 mm.

The suffix A indicates internal design improvements.

📐  Split type bearing seat
SKF's bearing housing product line is very extensive and is a key component that connects bearings and mechanical structures. Many models are not only used for Cooper split bearings, but can also be used for other standard bearings.

The main features of the bearing seat series are the types of bearings that are compatible with commonly used sealing forms
SAF/SAW inch size, large split vertical seat self-aligning ball bearings, spherical roller bearings, labyrinth seals, PosiTrac, etc
SNL metric size, split vertical seat, widely used for various bearing standard seals on tight fitting sleeves, Taconite (dustproof)
SONL oil lubrication with oil slinger, suitable for high speed and high temperature, mainly used for special sealing of oil lubrication for spherical roller bearings
FSAF flange mounted split bearing seat with self-aligning ball bearings and spherical roller bearings available in multiple options
SDAF large split bearing seat, commonly used in heavy industry spherical roller bearings, Cooper bearings, and various optional options
SNF Design for Cooper Split Bearing Seat Cooper Split Cylindrical Roller Bearing Matching Seal
ASNH is used for standard sealing of split bearing seat spherical roller bearings and self-aligning ball bearings with tight fitting sleeves
Model example interpretation: Taking SNL 513-611 as an example:

SNL: Bearing Seat Series.

513: Size series code.

611: Compatible tightening sleeve or bearing suffix.

💎  Suggested selection steps
To choose SKF split bearings, it is recommended to refer to the following steps:

Determine requirements: Clearly define the load, speed, shaft diameter, installation space, and maintenance convenience requirements for the application conditions.

Select bearing type:

Radial bearing is the main requirement for easy maintenance → Cooper split cylindrical roller bearings.

Need for self-aligning ability, ability to withstand heavy loads and deflection → BS2B split spherical roller bearing.

Determine bearing size: Refer to the official product list and find the corresponding bearing model and applicable load level (such as 02 and 03 series) based on the shaft diameter.

Optional bearing seat: Select the appropriate bearing seat from SAF, SNL and other series according to the bearing model and installation method (vertical, flange, etc.).

Completely disassembled with no dead corners: all components are cut in half, without the need to disassemble couplings or pulleys, and the shaft does not need to be pulled out, greatly reducing downtime
Spherical intermediate cylinder integrated seal: The seal is always concentric with the shaft, and the shaft is slightly eccentric without water or dust leakage. Ordinary split bearings do not have independent spherical cylinders and are prone to oil leakage
Factory preset clearance: No need to calculate or grind gaskets on site, beginners can quickly install them
Long life reinforced rollers and brass cage: 01E/02E enlarged rollers, with the same size bearing capacity far exceeding competitors, and MTBF increased by more than 50% under heavy load conditions
Full specification interchangeability and compatibility: can directly replace SN500, SD, SAF series domestically produced split bearing seats, without the need for frame processing for modification

Electric power/papermaking: fan, dryer, press roller, pulper (100/01E high-speed model)
Ship maritime: propulsion main shaft, intermediate shaft, thrust shaft (1DTB, marine 02E)
Metallurgical steel rolling: rolling mill auxiliary rolls, cold bed conveyor shaft (03E ultra heavy)
General machinery: large mixing, spiral conveying, elevator drive, sewage treatment equipment
Port lifting: belt transfer, stacker reclaimer drum (02E/03E heavy-duty)
7、 Core principles for installation and selection
Configuration rules for a transmission shaft
1 GR positioning bearing (bearing axial and locking shaft)
All others are equipped with EX floating bearings (absorbing shaft thermal expansion and contraction)
Large axial thrust condition: Replace the positioning end with a split tapered roller bearing
Heart regulating selection
Rack is prone to deformation, belt tension is high, and dust is severe → Priority is given to the BC self-aligning spherical series
Only radial load, pursuing speed cost-effectiveness → 01E cylindrical series
Narrow space, high-speed light load → 100 compact series
Environmental selection
High temperature>100 ℃: HT high temperature seal+high temperature grease
Slurry/Mud Water: Triple Maze+Double lip Sealed BC Centered Version
Food industry: GP food grade sealing, oil-free design

The self centering ability relies solely on the spherical cylinder ± 0.75 °, and the spherical cylinder ± 0.75 ° bearing comes with a spherical raceway, providing greater fault tolerance
Generally resistant to dust/mud (requiring thicker sealing), generally (requiring thicker sealing), original factory fully enclosed, multiple seals are optimal
Standard applications include fans, dryers, heavy-duty rollers for general conveyors, mixing shafts, spiral conveyor mining belts, and cement rotary pulleys
5、 Supplementary selection and matching rules
EX=floating end: no axial edge, allowing for thermal expansion and contraction of the shaft; One transmission shaft has only one GR positioning bearing, while the rest are all EX
GR=positioning end: double-sided blocking edges, capable of withstanding bidirectional axial forces; Replace long axis and high thrust working conditions with split tapered roller bearings
01BC comes with an integral sealing unit, eliminating the need for additional complex mazes; Cylinder 01E/02E needs to be equipped with Cartridge spherical intermediate cylinder to achieve centering and complete sealing
Load amplification factor: Take 1.2~1.6 for the belt conveyor; Mixing impact condition is taken as 1.8~2.5; The stable operating condition of the fan is taken as 1.0~1.2
