Description
Basic Parameters
In bearing 1300:
“1”: Indicates the bearing type is a self aligning ball bearing, characterized by a unique design with a spherical outer ring raceway. This allows the bearing to automatically compensate for shaft misalignment (up to 2-3 degrees), making it highly versatile in applications with potential misalignment issues.
“3”: Represents the diameter series code. The “3” series denotes a medium series, meaning the bearing has a moderate cross-sectional size relative to its inner diameter. This design balances load-carrying capacity and space requirements for practical applications.
“00”: Is the inner diameter code. For standard bearings, codes 00-03 correspond to specific inner diameters:
“00” = 10mm, “01” = 12mm, “02” = 15mm, “03” = 17mm.
Tolerance grade: Not explicitly indicated in the model, but typically assumed to be grade 0 (normal precision), suitable for general machinery with standard accuracy needs.
Self Aligning Ball Bearing Features:
Dual-row balls: Provide higher radial load capacity and self-aligning capability.
Spherical outer ring: Enables automatic adjustment to shaft misalignment caused by installation errors or thermal expansion.
Simple structure: Easy to install and maintain, even in environments with misalignment challenges.
