What Ships as a Set

Why a 2 mm Thrust Bearing

• Axial space is the constraint. A 20 mm bore thrust ball bearing needs roughly 8–14 mm of height. AXK2035 plus two washers needs 4 mm.
• High static capacity in a thin section. C_0a 46.5 kN against C_a 13.1 kN — that ratio tells you this bearing is built for shock and static holding rather than continuous high-speed running.
• Separable. The cage and washers install separately, which matters when the housing is closed on one side.
• Cheap to replace. Only the cage assembly wears; the washers are usually reusable.

Reading the Axial Numbers

If your axial load exceeds C_a, do not simply pick the next size up in the same 2 mm height — 35 mm OD is already the limit for a 20 mm bore at this section. Move to AXK2542 or accept a taller bearing.

Related Sizes in the Same Series

Load ratings for the other sizes are available on request — they are not published here to avoid quoting figures that differ from our production records.

Typical Applications

Installation and Mating Surfaces

• Axial load only. AXK2035 has no radial capacity — combine it with a radial bearing on the same shaft.
• One direction. For reversing axial load you need a second assembly facing the other way.
• Raceway requirement. Washer faces or hardened shaft/housing faces at 58–62 HRC, Ra ≤ 0.2 µm, flat, and fully supported over the E_a–E_b annulus. A soft or dished face will spall in a few thousand cycles.
• Assembly order: washer → cage assembly → washer. Keep the cage centred on the shaft while the housing goes on; the cage is located radially by the shaft, not by the housing.
• No preload. These are not preloaded angular contact bearings — a light axial clearance is normal.
• Lubrication: oil preferred, especially above 4 000 r/min. Grease is acceptable at low speed and low duty; fill the cage pockets, not the housing.

Quality Control on Every Batch

• 100% dimensional check on D_c1, D_c, D_w and washer thickness
• Washer hardness and flatness verified per lot
• Needle gauge sorting to 1 µm
• Rotation and noise check on assembled sets
• Material certificate 3.1 and inspection report with the shipment
• Anti-rust oil, VCI bag, carton

Frequently Asked Questions

What are the dimensions of AXK2035?

Bore D_c1 20 mm, outside diameter D_c 35 mm, height D_w 2 mm, raceway diameters E_a 34 mm and E_b 22 mm, cage assembly mass 5 g. The AS2035 washer is 20 × 35 × 1 mm.

Is AXK2035 a complete bearing?

No — it is a needle roller and cage assembly with no raceway of its own. It needs hardened, ground faces on both sides. This SKU ships with two AS2035 washers that provide them.

Can AXK2035 take radial load?

No. It is an axial-only component. A radial bearing must carry the shaft load, with the AXK2035 sitting alongside it.

What is the load rating of AXK2035?

Dynamic C_a 13.1 kN, static C_0a 46.5 kN and fatigue load limit C_ua 4.75 kN.

How fast can AXK2035 run?

Reference speed 4 350 r/min and limiting speed 10 500 r/min with oil lubrication. Grease-lubricated applications should stay well below the reference speed.

What surface finish do the washers need?

58–62 HRC and Ra ≤ 0.2 µm, flat, and fully supported over the E_a–E_b annulus. AS2035 already meets this; if you machine the raceway into the housing instead, match the same specification.

Which brands interchange with AXK2035?

AXK2035 is a standardized metric designation; INA/FAG, SKF, NTN, NSK and Koyo use the same code.
