Description

Product Overview

Timken’s Pinion Bearing model 19268 is engineered for the demanding environment of automotive power‑train applications. The bearing is forged from high‑grade alloy steel, a material chosen for its superior strength, wear resistance, and ability to maintain dimensional stability under high load and temperature conditions. Each bearing is precision‑machined to meet Timken’s exacting standards, ensuring a tight tolerance fit that reduces vibration and noise during operation. The external surface is painted with a protective coating that guards against corrosion and environmental contaminants, extending the service life of the component. With a compact cubic dimension of 5.91 inches on each side and a weight of approximately one kilogram, the bearing integrates seamlessly into standard pinion housings without requiring modifications. The design incorporates grease‑compatible seals, allowing the use of conventional automotive greases for lubrication, which simplifies maintenance and reduces the need for specialized lubricants. The bearing number 19268 is recognized across the industry, and the National Stock Number 3110‑00‑100‑0535 provides a reliable reference for inventory management. Timken’s reputation for quality and durability is reflected in this product, which is widely used in both original equipment manufacturers (OEM) and aftermarket repair scenarios. The bearing’s performance is validated by its ranking in Amazon’s automotive categories, indicating strong acceptance among mechanics and vehicle owners alike.

Usage

The Timken Pinion Bearing 19268 is suited for a variety of automotive and light‑industrial applications where a robust, reliable bearing is required. It is commonly installed in rear‑wheel drive vehicles, front‑wheel drive systems, and all‑wheel drive configurations that employ a pinion gear to transmit power from the transmission to the differential. The bearing’s alloy steel construction makes it ideal for high‑torque environments such as trucks, SUVs, and performance cars that experience frequent acceleration and deceleration cycles. In addition to passenger vehicles, the bearing can be employed in off‑road equipment, agricultural machinery, and marine applications where exposure to moisture and dust is common. The grease‑compatible design allows technicians to use standard automotive greases, making routine servicing straightforward and cost‑effective. Installation typically involves removing the old bearing, cleaning the housing, and pressing the new bearing into place using a calibrated press to avoid damage. The bearing’s dimensions align with standard pinion shaft specifications, eliminating the need for custom machining. Proper lubrication, periodic inspection, and adherence to torque specifications will ensure optimal performance and longevity. Users who follow recommended maintenance schedules can expect reduced wear, smoother gear operation, and improved fuel efficiency due to lower mechanical losses.

FAQ

What vehicles are compatible with the Timken Pinion Bearing 19268?

The bearing is designed to fit a wide range of passenger cars, trucks, SUVs, and light‑commercial vehicles that use a standard pinion shaft size. It is commonly used in rear‑wheel drive and front‑wheel drive configurations, as well as in some all‑wheel drive systems. Consult the vehicle’s service manual or contact Timken technical support for specific model compatibility.

How often should the bearing be lubricated?

Because the bearing is grease‑compatible, it should be lubricated during the initial installation and then inspected at regular service intervals, typically every 12,000 to 15,000 miles or as recommended by the vehicle manufacturer. Re‑greasing may be necessary if the bearing shows signs of noise, increased temperature, or reduced performance.

Can I replace the bearing myself, or do I need a professional?

While the bearing can be installed by a skilled DIY enthusiast, it requires proper tools such as a bearing press and torque wrench to avoid damage. If you are not familiar with press‑fit installations, it is advisable to have a qualified mechanic perform the replacement to ensure correct alignment and seating.

What warranty does Timken provide for this bearing?

Timken offers a limited warranty that covers manufacturing defects for a period of one year from the date of purchase. The warranty does not cover damage caused by improper installation, misuse, or unauthorized modifications. Detailed warranty terms are available on Timken’s official website or through the authorized retailer.

Is the bearing suitable for high‑performance or racing applications?

Yes, the alloy steel material and precision engineering make the bearing suitable for high‑torque and high‑speed applications, including performance and racing vehicles. However, for extreme racing conditions, users may opt for specialized high‑performance bearings that are specifically tuned for those environments.
