Standard Series & Models
Our self-aligning ball bearings are organized into four primary series to suit light, medium and heavy-duty working conditions:
12 Series
Compact and lightweight, ideal for high-speed small machines with limited installation space.
Popular models: 1204, 1205, 1206, 1207, 1208
13 Series
Well-balanced load and speed performance, suitable for most general industrial machinery.
Popular models: 1305, 1306, 1307, 1308, 1309
22 Series
Higher load capacity than the 12 series, engineered for stable continuous running.
Popular models: 2205, 2206, 2207, 2208, 2209, 2210
23 Series
Highest load rating in the range with good shock resistance, designed for heavy-duty equipment.
Popular models: 2305, 2306, 2307, 2308, 2309, 2310
Clearance & Cage Options
ZWZ standard self-aligning ball bearings are produced with internal clearances conforming to GB4604, including C2, CN (normal), C3, C4 and C5. Custom clearances above or below standard levels are also available upon request.
Cage designs include pressed steel cages, brass machined cages and nylon (polyamide) cages:
● For bearings with outer diameter D ≤ 200 mm, pressed steel cages are used as standard
● For bearings with outer diameter D > 200 mm, brass machined cages are applied
● Nylon cages can withstand operating temperatures up to 120°C
● For continuous high-temperature or severe working conditions, brass machined cages are recommended
Key Benefits
● Cylindrical bore design simplifies installation, removal and on-site maintenance
● Double-row construction delivers reliable radial load capacity and smooth running
● Full size range in stock with customizable sealing, shielding and clearance options
● Spherical outer raceway effectively compensates for misalignment and shaft bending
● Low friction lowers energy consumption and helps extend service life
