AS3047 ISB washer

ISB AS3047 Thrust Washer (Thin Raceway)

The ISB AS3047 is a high-precision raceway washer made from hardened chrome steel. The AS series rings are characterized by their extremely thin profile, enabling the design of ultra-flat bearing arrangements. Both surfaces are polished, allowing them to work directly as raceways for AXK needle roller thrust assemblies or cylindrical roller cages. It is the perfect solution when high axial load capacity is required within critically limited mounting space.

Application

• Gearboxes and Reducers: Compact support for rotating elements under axial pressure.
• Precision Machine Tools: Providing a stable rotation plane for positioning mechanisms.
• Clutches and Brakes: Managing axial forces in narrow mechanical sub-assemblies.
• Pumps and Valves: Resistance to point-load stress from rollers in demanding conditions.
• Automation and Robotics: Precise axial guidance in lightweight arms and grippers.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: AS3047
• Type: Thin-walled thrust washer
• Material: Hardened bearing steel (high surface hardness).
• Compatibility: AXK3047 needle thrust assemblies.

Note: Standard dimensions for the AS3047 are 30 mm (Bore) × 47 mm (OD) × 1 mm (Thickness).

Features and Benefits

• Space-saving Design: A thickness of only 1 mm allows for extreme miniaturization of the bearing unit.
• High Mechanical Resistance: Hardened surface prevents pitting and wear under heavy axial loads.
• Dual-sided Functionality: Both sides are ground with equal precision, simplifying installation.
• Housing Protection: Absorbs friction from rolling elements, protecting non-hardened machine parts from wear.
• ISB Quality Standards: European manufacturing ensures perfect parallelism and a superior surface finish.

Why Choose This Product

The ISB AS3047 thrust washer is the most efficient way to establish a professional raceway for needle thrust bearings in tight spaces. It eliminates the need for hardening shafts or housings, providing a smooth and hard track for the rollers. By selecting ISB, you invest in a component that minimizes heat generation and significantly extends the operational lifespan of your mechanical systems.
