AS 2035 INA 20x35x1 mm - Thrust Washer / Bearing Washer

Applications

The AS 2035 INA thrust washer (dimensions 20 mm ID x 35 mm OD x 1 mm thickness) is a precision-engineered component used in industrial bearing units and bearing housings to control axial clearance or provide axial support for rolling elements. Designed for integration with needle roller or deep groove ball bearing assemblies, it ensures smooth operation and dimensional stability of the bearing unit under load.

Commonly used in electric motors, gearboxes, automation machinery, pumps, and mechanical drive systems, the AS 2035 washer enhances performance by stabilizing the bearing arrangement and protecting against excessive axial movement. Its compact form allows installation in confined spaces, making it suitable for both OEM production and maintenance operations.

Key Advantages

• Precision fit (20x35x1 mm) - guarantees exact alignment in industrial bearing housings and units, reducing assembly time and tolerance errors.

• High durability - manufactured from hardened steel sheet for long service life in demanding mechanical environments.

• Axial support and stability - provides reliable load distribution in bearing units and reduces wear caused by axial movement.

• Easy integration - fits standard bearing housing systems and units without modification, enabling immediate installation.

• Industrial compatibility - designed for bearing assemblies operating under continuous duty, temperature variation, and moderate contamination.

Product Description

The AS 2035 INA 20x35x1 mm thrust washer is a reliable and durable bearing accessory engineered to ensure precise axial guidance within industrial bearing units. Its primary role is to limit axial play and support rolling elements, maintaining proper alignment and operational consistency.

Made from high-strength, hardened steel, the AS 2035 provides long-term wear resistance and performance in heavy-duty applications. It is compatible with INA needle roller bearings and other bearing arrangements requiring a flat, precision-machined washer to carry axial loads.

This washer is widely used in gearboxes, motors, automation systems, and mechanical assemblies, where it helps extend bearing life and ensures stable operation under constant load. Its standard dimensions (20x35x1 mm) guarantee easy integration into existing designs and simplify replacement processes during equipment maintenance.

The AS 2035 INA represents a balance between compactness, accuracy, and endurance, supporting long-term reliability in both OEM and aftermarket industrial use.

FAQ

Q1: What is the function of the AS 2035 INA washer?
A1: It serves as a thrust washer that supports axial loads and controls clearance in bearing units and housings.

Q2: Is this part a bearing or a bearing accessory?
A2: It is a bearing accessory - a flat thrust washer used with needle or ball bearings to stabilize axial movement.

Q3: What materials is the AS 2035 made from?
A3: High-grade hardened steel with precision surface treatment to ensure optimal flatness and resistance to wear.

Q4: Can it be used in standard bearing housings?
A4: Yes - the AS 2035 fits standardized bearing unit assemblies and is compatible with most INA and industrial housing designs.

Q5: Does it require lubrication or maintenance?
A5: No - the washer itself is maintenance-free; it operates as a support element within a lubricated bearing assembly.
