S-5909K55 1.752" ID x 2.5" OD Washers for Needle-Roller Thrust Bearings

Key Features & Benefits at a Glance

• Precise fit for 1 3/4" shafts with controlled ID tolerance (0" to +0.01") ensuring reliable assembly and reduced vibration in mechanical systems.
• Enhanced load distribution thanks to the 2.5" outer diameter, minimizing surface pressure and preventing damage to connected components.
• Consistent thickness of 0.032" with tight tolerance (-0.002" to 0") for uniform performance and predictable spacing in stacked applications.
• Manufactured from durable steel providing excellent strength and resistance to deformation under high-stress industrial conditions.
• Full compliance with RoHS 3 and REACH regulations ensuring safe, environmentally responsible use in global markets without hazardous substances.
• Optimized for inch-system applications as a reliable alternative where metric components are not suitable, facilitating easy sourcing and replacement.
• Accurate OD tolerance control (-0.03" to -0.01") allows for smooth integration into standard housings, reducing installation time and errors.

Professional Applications & Engineering Value
