SKF Bearing Insert 45 mm ID 85 mm OD 1726209-2RS1

This bearing insert is a sealed steel rolling element for integration into housings where a cylindrical bore is required. It is intended for mechanical assemblies in industrial settings that demand controlled rotational performance and protection from contaminants. The component is manufactured to withstand continuous operation in equipment used across automation, electronics and electrical systems.

• Sealed construction reduces contamination ingress and maintenance
• Limiting speed 5000 r/min supports high-speed rotational tasks
• Dynamic capacity 33.2 kN handles variable operational loads
• Static capacity 21.6 kN resists shock and static loading scenarios
• Cylindrical bore design ensures accurate shaft alignment

• Suitable for motor and gearbox shaft support in automation
• Ideal for bearing housings in electrical drive systems
• Used with rotating assemblies in production-line machinery
• Can be used for precision rotary components in electronics equipment

The insert is MADE from steel, providing structural strength for rotational duty and contact resistance under load.

The sealed end type limits ingress of dust and fluids, which reduces the frequency of re-lubrication and inspection in dusty or humid environments.

It is designed for a cylindrical shaft Interface with a 45mm internal diameter to ensure a snug fit and concentric operation.

The outside diameter measures 85mm, which determines bore size in housings and informs machining tolerances for press-fit or clamp-in installations.

The overall width is 19mm, so designers should accommodate this thickness when specifying axial clearances and retaining features.
