7209 BECBP Single‑Row Angular Contact Ball Bearing 45×85×19mm 40° Polyamide Cage For Spindle Pump

The 7209 BECBP is a single‑row open angular contact ball bearing with 40° contact angle and glass‑fiber reinforced polyamide cage, designed for high‑speed machine‑tool spindle and pump assemblies. It supports combined radial and one‑directional axial loads and is suitable for universal pairing mounting.

It is widely used for spindle, pump and gearbox where high‑speed and moderate‑rigidity performance are required.

• High combined radial‑axial load capacity for high‑speed industrial applications
• 40‑degree large contact angle improves unidirectional axial stiffness
• Light‑weight polyamide cage for low‑inertia stable high‑speed rotation
• Available for DF / DB / DT paired mounting arrangements
• Suitable for machine spindle, pump and gearbox transmission equipment
• Custom design available (clearance, preload, OEM laser marking)

This bearing is widely used in:

• Machine‑tool spindle and intermediate support assemblies
