GQZ 1209K Self-Aligning Ball Bearing 45×85×19mm With Tapered Bore For Textile & Agricultural Machinery

1209K is double row self-aligning ball bearing with tapered inner bore. The spherical outer ring raceway delivers excellent self-aligning performance to compensate shaft deflection and housing alignment deviation. Tapered bore enables mounting by using an adapter sleeve for convenient installation and disassembly. It can bear radial load and small bidirectional axial load simultaneously. Widely used in textile machinery, agricultural equipment, fans, conveyors and rotary assemblies where alignment deviation exists.
