Timken 1187S Wheel Seal - Rear

Timken 1187S Wheel Seal Overview

Timken 1187S is a wheel seal built for driveline and axle sealing applications where lubricant retention and contamination control matter. Its S-Nitrile construction, reinforced outer case, and ribbed inner diameter support a secure seal at the spindle and housing interface.

For wheel seal replacement on axle assemblies, Timken 1187S helps maintain proper grease or oil containment while resisting debris intrusion. It is a practical choice for service work on vehicles such as Honda Civic and similar applications that require a 1.850 shaft diameter and 2.677 housing bore.

Key Features

• S-Nitrile sealing material for durable lubricant sealing performance
• Outside diameter: 2.688 in. / 68.27 mm
• Housing bore: 2.677 in. / 68.00 mm
• Shaft diameter: 1.850 in. / 47.00 mm
• Width: 0.394 in. / 10.00 mm
• Reinforced outer case helps reduce installation damage
• Ribbed rubber inner diameter seals minor spindle imperfections and supports seating
• Internal contamination exclusion system helps block debris entry

Detailed Description

Timken 1187S is engineered as a wheel seal for axle and hub sealing service, with dimensions that matter for accurate replacement: 2.688 outside diameter, 2.677 housing bore, 1.850 shaft diameter, and 0.394 width. The seal’s ribbed inner diameter helps it conform to minor spindle irregularities, while the reinforced outer case adds durability during installation and service. This part cross-references Gates 18470 for the same application.

For technicians and DIY repairs searching for a Timken 1187S wheel seal, this part supports clean lubricant retention and contamination control in driveline and axle assemblies. It is a direct-fit style sealing component for applications that call for these exact dimensions, including select Honda Civic wheel seal service needs.

What It Helps Solve

• Grease or oil leakage at the wheel seal area
• Contamination entering the hub or spindle seal zone
• Seal wear caused by heat buildup around the lip
• Poor sealing on minor spindle surface imperfections
• Damage during seal installation or removal

Installation Notes and Tips

Verify shaft diameter, housing bore, outside diameter, and width before installation. Clean the spindle, hub, and sealing surfaces thoroughly, and inspect for scoring or wear that could affect seal seating. Press the seal in evenly to avoid distorting the outer case or damaging the sealing lip. Confirm the seal sits squarely in the bore before returning the vehicle to service.

For fitment-based searches, Timken 1187S is commonly referenced for wheel seal replacement on Honda Civic applications where these dimensions match the original seal specification.

Quality Assurance

Timken is known for precision sealing designs in oil and grease seal applications. The 1187S uses a reinforced case, contamination exclusion features, and venting details to support consistent sealing performance in axle and wheel-end service.
