ICOS-D1B05 TN9

• ICOS-D1B05: Manufacturer's base designation for this specific bearing size and series.
• TN9: Denotes the cage material and type. The "T" indicates a Nylon (Polyamide) cage, and "N9" specifies a particular design or reinforcement, contributing to reduced friction and suitability for high limiting speeds.
• No Sealing Suffix: The absence of a seal designation (like 2Z or RS) confirms this is an Open bearing, optimized for applications where external sealing is handled separately or where maximum speed is critical.
• No Lubrication Suffix: The specification "Lubrication: None" indicates the bearing is supplied without grease, allowing for application-specific lubrication selection.

High-Speed Performance: The TN9 Nylon cage is a key feature, offering excellent strength-to-weight ratio and inherent lubricity. This minimizes centrifugal forces and friction, enabling the bearing to achieve its high limiting speed of 7,700 rpm.

Radial Load Capacity: The deep groove raceway geometry is optimized to support significant radial dynamic load ratings (3327 lbf) and radial static load ratings (1754 lbf), providing reliable performance under demanding conditions.

Precision and Rigidity: Manufactured to a P6 tolerance class with strict dimensional controls on the bore diameter (25 mm), outside diameter (52 mm), and width (15 mm), this bearing ensures minimal runout and high system rigidity for precise applications.

Material Integrity: Constructed entirely from chrome steel for both rings and balls, the bearing offers high hardness, wear resistance, and a consistent operating temperature range of -30°C to 120°C.

This high-precision, open-style bearing is commonly specified in:

• Electric Motors and Small Spindles where high speeds and precision are paramount.
• Precision Instruments and Medical Devices requiring reliable, low-friction rotation.
• Office Automation Equipment such as printers and scanners.
• Industrial Pumps and Fans that operate at high rotational speeds.
