INAAS130170Axial Bearing Washer – 130 mm Bore, 170 mm OD, 1 mm Thick, DIN 5405-3, 5 Pcs

Product Description

What this part is

INA AS130170 axial bearing washer to DIN 5405-3 / ISO 303. It is a hardened and ground steel washer that provides the raceway for an axial needle roller and cage assembly where the adjacent machine face is not hard enough to serve as one. Bore Diameter: 130 mm. Outside Diameter: 170 mm. Overall Width: 1 mm. Item Weight: 0.069 kg (0.15 lb). Series: AS. Base Number: AS130170. Bearing Material: Hardened steel. GTIN: 035373021673.

Decoding the designation

AS — axial bearing washer, the flat raceway disc of the DIN 5405 thrust needle bearing system.

130 — bore diameter in millimetres.

170 — outside diameter in millimetres.

What these specs mean in practice

Thrust needle roller assemblies in the AXK and K811 families are supplied as a cage and roller set alone. Both faces they bear against have to be hardened to 670 HV and ground, and where a housing or shaft face cannot be treated that way, an AS washer supplies the raceway instead. At 1 mm thick it adds almost nothing to the axial stack, which is the point of the design.

The 130 x 170 mm dimensions match the AXK130170 and K811130170 sizes directly.

Mounting data

Washer height: 1 mm, so a thrust assembly using washers on both faces adds 2 mm to the height of the cage-and-roller set.

Quantity and configuration

Unit Quantity: 5 Pcs. Five washers in the listing.

Interchange guidance

AS130170 is a DIN 5405-3 / ISO 303 standard designation, and the needle bearing makers use it unchanged, so the cross-references below are direct interchanges on dimension and function. Designation variants: AS 130170, AS-130170, AS130 170.
