National Ball Bearing HB88515 Alloy Steel with Advanced Heat Treatment

Description

Product Overview

The National HB88515 ball bearing is engineered for high‑performance environments where reliability and longevity are paramount. Constructed from premium alloy steel, each bearing undergoes an advanced heat‑treatment cycle that enhances hardness, reduces wear, and improves resistance to fatigue. The result is a component that can sustain heavy radial and axial loads while maintaining precise rotational accuracy. With dimensions of 12.4 x 10.3 x 9.5 inches and a weight of 4.11 pounds, the bearing fits seamlessly into a wide range of automotive and industrial assemblies. Its machined exterior provides a smooth surface for optimal contact with housing and shaft components, ensuring consistent performance over the product’s service life.

Usage

This bearing is suited for both OEM replacement and aftermarket upgrades across a variety of vehicle and machinery platforms. It excels in applications such as transmission systems, drive shafts, and gearboxes where high torque transmission and minimal vibration are critical. The bearing’s design complies with original equipment (OE) specifications, making it a direct fit for many domestic and import models. In industrial settings, it supports conveyor rollers, pump shafts, and other rotating equipment that demand steady operation under continuous load. The compatibility with standard grease lubricants simplifies maintenance, while the robust construction tolerates harsh operating temperatures and exposure to contaminants.
