SKF Bore Seal Alloy Steel Input Shaft Grey 9815

Description

Product Overview

The SKF Bore Seal is engineered for demanding power transmission applications where durability and reliability are paramount. Constructed from high‑grade alloy steel, the seal offers superior strength and resistance to deformation under load. The inner bore measures 1.25 inches nominally, while the outer diameter matches the same dimension, ensuring a precise fit on standard input shafts. A single steel case houses a nitrile rubber sealing lip, providing excellent chemical resistance and wear protection. The grey machined exterior not only adds a professional appearance but also aids in heat dissipation during operation.

Usage

Designed for automotive and industrial transmission systems, this seal excels in grease‑lubricated environments operating at moderate speeds. It is ideal for replacement of automatic transmission input shaft seals, as well as for new builds in power‑train assemblies. Technicians and mechanics will find the seal easy to install on shafts ranging from 1 to 1.25 inches, making it suitable for a variety of vehicle models and machinery.

Why Choose Us

SKF’s reputation for precision engineering ensures that each Bore Seal meets stringent quality standards. The single‑piece steel case eliminates the risk of case separation, while the nitrile rubber lip resists oil, fuel, and coolant exposure, extending service life. Our seals undergo rigorous testing for dimensional accuracy, pressure resistance, and temperature stability, guaranteeing consistent performance in the field. Additionally, the seal’s design minimizes contaminant ingress, protecting internal components and reducing maintenance costs.

FAQ

What type of lubricant should be used with this seal?

SKF recommends using high‑quality grease that meets the specifications for the specific transmission. The nitrile rubber lip is compatible with most automotive greases.

Can this seal be used on shafts larger than 1.25 inches?

No, the seal is designed for a nominal inside diameter of 1.25 inches. Using it on larger shafts may result in inadequate sealing and premature wear.

Is the seal reusable after removal?

While the steel case can be inspected for damage, the nitrile rubber lip should be replaced after removal to ensure optimal sealing performance.

What temperature range does the seal support?

The seal operates reliably within a temperature range of -40°C to 120°C, covering most automotive and industrial applications.

How does the seal protect against contaminants?

The sealing lip creates a tight barrier that prevents dust, water, and debris from entering the transmission, thereby extending component life.
