9168305 25x52x16mm Automotive Steering Bearings Ball Bearings

Product Overview

The 9168305 is a single-direction thrust angular contact ball bearing, purpose-built for automotive steering gear and steering column assemblies. It crosses to the newer Chinese designation 569305, and the 9168305 → 569305 interchange is the standard reference for sourcing and identification. The bearing measures 25 mm bore × 52 mm outside diameter × 16 mm height and is produced from GCr15 chrome steel.

Critical structural correction: thrust angular contact, not radial angular contact

The supplier form classifies the structure as “Angular contact ball bearings” with “Single” rows and “Axial & Radial” load direction. Multiple Chinese bearing databases consistently identify a more specific and operationally different classification:

• Bearing type: The 9168305 / 569305 is listed as a thrust angular contact ball bearing, with the sub-classification explicitly given as single-direction thrust angular contact ball bearing.

• Contact angle: Thrust angular contact ball bearings of this class typically use a 60° contact angle .

• Load direction: As a single-direction thrust bearing, it is designed to carry axial load in one direction. The “Structure” field should be corrected from “Angular contact ball bearings” to “Thrust angular contact ball bearings (single-direction)”, and the Load Direction field should be corrected from “Axial & Radial” to “Axial (unidirectional)”. A radial angular contact ball bearing of the same envelope would imply radial load capability that this design does not provide.

Weight and performance data: not published, use with qualification

The supplier form leaves Weight, Cr, C0r, and speed ratings blank. Accessible Chinese bearing databases for the 9168305 / 569305 consistently show Cr, C0r, grease speed, oil speed, and weight as “-” or “0”, indicating that these values are not published for this specific part number . This is typical of vehicle-specific steering service bearings, which are specified by fitment and assembly position rather than by standard catalogue load ratings.

The closest published weight reference comes from the closely related variant 569305X2 / 168705, which shares the same 25 × 52 mm envelope but has a 15 mm height and is listed at 0.135 kg . The 9168305 / 569305 itself has a 16 mm height, so its mass should be similar or marginally higher (≈ 0.14 kg). The Weight field should be populated with ≈ 0.135–0.14 kg and noted as a variant-based reference, or left as “Consult supplier” if the platform requires manufacturer-confirmed data.

Key Specifications

Performance Features

• Unidirectional axial thrust capacity for steering service: The single-direction thrust angular contact geometry is configured to absorb the axial thrust generated during steering input in the steering gear or steering column, which is the dominant load direction in these mechanisms. The 60° contact angle provides high axial rigidity .

• GCr15 chrome steel construction: Rings and balls are produced from through-hardened GCr15 chrome steel, providing rolling-contact fatigue resistance for the cyclic axial loading of steering actuation.

• Steel cage: The steel plate cage is standard for this bearing family and retains and guides the balls under the oscillating, low-speed duty of automotive steering components .

• Open, grease-lubricated configuration: The bearing is supplied without integral seals and is packed with grease during steering assembly. The open design permits direct inspection and relubrication where the steering gear or column design allows access.

• Single-direction design with defined mounting orientation: Because the bearing carries axial load in one direction only, correct installation orientation is critical. The 569305/9168305 is typically installed in a steering gear or column position where the thrust direction is known and consistent.

Application

The 9168305 is an automotive steering bearing used in steering gear (方向机) and steering column assemblies. It is listed in steering bearing catalogues alongside other steering gear components and is associated with hydraulic and electro-hydraulic power steering systems. In service, a bearing of this type supports the steering screw, steering nut, or steering shaft within the steering gear, absorbing the axial thrust generated when the steering wheel is turned and maintaining smooth steering feel without binding or excessive play. The 569305 designation is the standard interchange for sourcing, and the bearing’s 25 × 52 × 16 mm envelope matches the mounting dimensions of the steering gear position it serves.
