1304 Self-Aligning Ball Bearing / 1304K | Bearing Steel And Stainless Steel
The 1304 self-aligning ball bearing is a widely used double-row rolling bearing with a spherical outer raceway. It provides excellent self-aligning performance to compensate for shaft misalignment and installation deflection, delivering low-friction, quiet and stable rotation for light and medium-duty mechanical equipment. Available in standard straight bore 1304, tapered bore 1304K, bearing steel and stainless steel versions, this bearing operates reliably in dry, humid and sanitary industrial environments.
Difference Between 1304 and 1304K
1304 (Standard Bore): Adopts a straight cylindrical inner bore for fixed shaft matching. It features simple installation, stable operation and convenient disassembly, suitable for general machinery with fixed assembly and no frequent adjustment needs.
1304K (Tapered Bore): Designed with a 1:12 tapered inner bore, compatible with standard adapter sleeves. It supports flexible installation, precise clearance and preload adjustment, enabling easy maintenance and calibration, ideal for variable-speed transmission and frequently adjusted mechanical equipment.
Material Differences: Bearing Steel vs Stainless Steel
Bearing Steel (GCr15): GCr15 bearing steel is the cost-effective standard material for 1304 and 1304K bearings. After precision heat treatment, it offers high hardness, excellent wear resistance and strong anti-fatigue performance. It maintains stable load capacity and smooth rotation under conventional dry conditions, perfect for general industrial machinery and ordinary transmission systems.
Stainless Steel: Stainless steel 1304/1304K bearings possess superior rust-proof, oxidation and weak corrosion resistance. They effectively resist moisture, humid air and minor contamination, avoiding precision attenuation and corrosion failure, making them ideal for damp, clean, sanitary and mild outdoor working scenarios.
Product Features
Excellent self-aligning capability offsets mounting errors and shaft deflection. Double-row ball structure ensures stable load capacity with low-noise, smooth operation. Dual bore designs meet fixed and adjustable installation requirements. Two material options cover economical general use and anti-corrosion precision applications. Standard compact size ensures easy installation and long service life.
Application Scenarios
1304 and 1304K self-aligning ball bearings are widely applied in small and medium motors, industrial fans, textile machinery, light conveyor equipment and general automation devices. Bearing steel models suit conventional indoor mechanical equipment; stainless steel versions fit food machinery, medical devices and humid environment equipment. 1304K tapered bore bearings are preferred for equipment requiring frequent debugging and assembly adjustment.
