📜 About the brand: Centennial split bearing expert
COOPER is a British bearing manufacturer with more than a century of history. Thomas Cooper invented the world's first set of completely separable bearings in 1907 and is the pioneer and market leader in this segment. In 2013, COOPER officially joined the global bearing giant SKF Group and now operates under the "SKF Cooper" joint brand. Its products cover the shaft diameter range from 30mm to 1500mm.

🧩 Core products: more than one choice
SKF Cooper provides various types of split bearings to suit different working conditions.

Split Cylindrical Roller Bearings: This is COOPER’s core and most widely used product line. Depending on the load-bearing capacity and compactness, multiple options are available, from the "100 Series" for light load and high speed to the "03 Series" suitable for extremely heavy load conditions.

Split Spherical Roller Bearings (Split Spherical Roller Bearings): have automatic self-aligning capabilities and can compensate for shaft alignment errors. They are specially designed to withstand heavy loads and impact conditions. Two main size segments are provided: 80-200mm and 240-450mm. SKF has also expanded the new size range of 80-135mm based on this series.

Split Tapered Roller Bearings: Designed to withstand high combined radial and axial loads, usually used as "fixed end" (GR) bearings.

Bearing seats and seals: Provides various models such as standard plummer housing (BCP) and flange bearing housing (BCF), as well as various levels of sealing options such as aluminum triple labyrinth seal (ATL) and synthetic rubber seal (SRS) to adapt to different environments.

📖 Model Interpretation: How to understand the COOPER bearing code
COOPER bearing models follow a clear set of naming rules, and understanding it can quickly obtain key information.

Example model: 01EB70MGR

part meaning explanation
01 series number (Series) represents 01 series, the most commonly used series for medium-sized applications.
E Enhanced E stands for "enhanced", providing higher carrying capacity.
B Design Option B usually refers to the brass cage.
70 Bore Size (Bore Size) 70 means that the bearing inner diameter is 70 mm.
M Metric (Metric) M indicates that the size unit is millimeters (metric).
GR Bearing Type GR=Fixed, EX=Expansion.
Fixed end (GR) vs. floating end (EX): Usually used in pairs on the shaft, one GR is responsible for axial positioning, and the rest use EX to compensate for thermal expansion and contraction to avoid additional stress.

💡 Selection Guide: Key steps for the right choice
Clarify the working condition requirements: including shaft diameter, load type, rotation speed, working environment and whether disassembly of surrounding equipment is allowed.

Select the bearing type: According to the nature of the load: cylindrical roller bearings are selected for pure radial loads; spherical roller bearings are selected for heavy loads with deflection compensation requirements; tapered roller bearings are selected for combined loads (radial + axial).

Overview of installation steps:

Check the shaft: Measure the shaft diameter to ensure tolerances are correct.

Grease: Apply a thin, even layer of lubricant to the shaft.

Install the inner ring: Place the two halves of the inner ring on the shaft, making sure that the matching marks on all parts are aligned and there is a gap.

Install Clamping Rings: Install and tighten the clamping rings with a torque wrench.

Assemble the outer ring and rolling elements: Assemble the cage, rollers and outer ring according to the instructions.

Install Seals: Install seals correctly according to the type of seal selected.

Note: SKF Cooper bearings have preset internal clearance at the factory and do not need to be adjusted on site during installation.

⚙️ Lubrication and sealing
Lubrication: Hearing the sound of metal grinding is usually a sign of lack of oil. It is recommended to replenish or replace the grease regularly.

Sealing: The sealing cover can effectively prevent external contaminants from entering and retain grease. Please do not remove it at will.
