MF 85 ZZ ZEN Flanged Ball Bearing 5x8x2.50 mm

MF 85 ZZ ZEN Flanged Ball Bearing 5x8x2.50 mm

The MF 85 ZZ ZEN is a metric miniature flanged ball bearing with bore 5 mm, outer diameter 8 mm and width 2.50 mm. It includes a flange (~9.2 mm Ø, ~0.6 mm thick) and double metal shields (ZZ) on both sides to protect from dust and retain lubrication.

Key Features

• Dimensions: 5x8x2.50 mm, flange Ø ~9.2 mm, thickness ~0.6 mm

• Shielding: ZZ metal shields (non‑contact) for extended life and maintenance‑free operation

• Material: Chrome steel (GCr15 / 52100); balls and cage stainless steel or equivalent for durability and corrosion resistance

• Performance: Rated dynamic load ~0.185-0.262 kN, static ~0.09-0.096 kN; max speed up to 53,000-59,000 RPM (grease/oil)

• Temperature range: approx. -30 °C to +110 °C (some specs up to +120 °C)

Applications
Commonly used in high-speed, compact applications such as miniature electric motors, robotics, drones, medical devices, RC models, light conveyor systems, and small precision machinery. Excellent choice as a 5 x 8 x 2.5 flanged bearing, shielded bearing, ZEN bearing.

Why choose this bearing?

• Ultra-compact yet robust design

• Maintenance‑free due to double metal shields

• High rotational speed capabilities

• Reliable thermal and wear resistance

• Easy flange mounting for stable axial positioning
