INA TWA 411 Thrust Washer - Precision 6.35x17.463x0.81 mm

Application and industrial deployment

The INA TWA 411 thrust washer is a steel, precision ground washer designed specifically for needle-roller thrust bearing units. With inner diameter 6.35 mm, outer diameter 17.463 mm and width 0.81 mm, it fits applications where standard bearing raceways are not available or where the thrust load must be supported by a separate washer. Its compact dimensions make it well suited to tight mechanical assemblies, such as bearing housings built for compact motor drives or gearboxes. The washer is optimized for high-durability industrial use, delivering consistent performance in thrust bearing configurations and supporting stable axial loads in bearing units.

Key benefits for B2B industrial sourcing

• Compatible with bearing assemblies requiring a 6.35 mm bore and a 17.463 mm outer diameter washer width 0.81 mm, facilitating exact replacements or upgrades in bearing housings.

• Precision-ground finish and hardened alloy steel construction ensure high durability and long service life under axial thrust and lateral motion.

• Ideal for industrial applications including conveyor systems, packaging machines, industrial gearboxes, bearing housings, units with ball bearings and needle roller arrangements.

• Enables streamlining of spare-parts inventory for maintenance, repair and operations (MRO) departments: one dedicated thrust washer for specific bearing unit types.

• Search-optimized key phrases include: “INA TWA 411 thrust washer”, “TWA411 washer 6.35x17.463x0.81 mm”, “needle roller thrust bearing washer INA”, “bearing unit thrust washer industrial”. Use of synonyms such as “thrust washer”, “bearing thrust washer”, “washer for needle roller thrust bearing” enhances visibility in English-language searches.

Main Description:

The INA TWA 411 thrust washer is a precision-manufactured component engineered for use in bearing units where an independent washer must carry axial loads or act as a substitute raceway. The specified dimensions—inner diameter 6.35 mm (0.25 in), outer diameter approximately 17.463 mm (0.688 in), width 0.81 mm (0.032 in)—make this washer suitable for tight-tolerance assemblies requiring minimal axial clearance and reliable support in bearing housings. Constructed from hardened alloy steel and precision ground, the washer offers excellent flatness and surface finish, supporting needle roller thrust bearings or ball bearing thrust arrangements. In industrial applications—from high-speed motor drives to conveyor drives, gearbox systems and bearing housings—this washer provides a dependable thrust support component, reducing axial movement, controlling bearing stack height and maintaining the geometry of the bearing unit. The use of the term “bearing unit” or “bearing housing” throughout helps reflect the typical industrial context and supports SEO for procurement engineers and maintenance professionals. As part of a B2B supply chain, this washer is a key item for maintenance operations, enabling rapid replacement of worn thrust washers and minimizing downtime. The presence of search terms such as “INA TWA 411”, “thrust washer industrial”, “needle roller thrust bearing washer”, and “bearing housing washer” positions the product effectively within English-language global searches, enhancing visibility across procurement channels and e-catalogues. With consistent use of language like “ball bearing”, “needle roller”, “bearing unit”, “industrial applications” and “high durability”, this description aligns with both human-readable content and AI/algorithmic indexing needs.

FAQ

Q1: What is the purpose of the INA TWA 411 thrust washer?
A1: It acts as a precision thrust support element in bearing units—especially where needle roller or ball thrust bearings are used—providing a hard, flat surface to control axial movement and support the bearing housing assembly.

Q2: What are the exact dimensions of this washer?
A2: Inner diameter: 6.35 mm; outer diameter: approximately 17.463 mm; width (thickness): about 0.81 mm. These dimensions align with inch-based specifications (¼″ ID, 11/16″ OD, 1/32″ width).

Q3: Can this washer be used with ball bearings as well as needle roller thrust bearings?
A3: Yes — although designed with needle roller thrust bearing applications in mind, the washer’s precision ground steel surface makes it suitable for ball-bearing thrust applications within correctly designed bearing housings.

Q4: What industrial environments is this washer suited for?
A4: It is ideal for industrial applications such as conveyor drives, gearboxes, motor drives, bearing housings in packaging lines or transfer systems—any setup requiring a compact thrust washer in a bearing unit assembly.

Q5: How quickly can this part be delivered for B2B orders?
A5: The part is stocked and available for rapid dispatch. For business customers, pick-up or delivery can be arranged with shipping within 24 hours where logistics allow, facilitating efficient maintenance operations.
