Description

Product Overview

The FAG QJ308TVP is a single‑row angular contact ball bearing engineered for high‑performance power transmission. With a 35° contact angle, it efficiently manages combined axial and radial loads, making it suitable for demanding industrial applications. The open design allows for easy lubrication and quick inspection, while the polyamide nylon cage ensures precise roller spacing, reduces friction, and minimizes noise during operation.

Constructed from high‑quality steel rings, this bearing offers excellent durability and resistance to wear. The normal (CN) radial internal clearance is optimized for environments where thermal expansion is minimal, providing consistent performance without the need for special adjustments. Its dimensions—40 mm inner diameter, 90 mm outer diameter, and 23 mm width—fit standard shaft and housing configurations.

Operating at speeds up to 8,500 rpm, the QJ308TVP maintains stability even under high‑velocity conditions. The polyamide nylon cage not only reduces weight but also enhances corrosion resistance, extending the bearing’s service life in harsh environments. The open type design further protects the bearing from contaminants while allowing for targeted lubrication in place.

Designed by Schaeffler Technologies, a leader in precision engineering, this bearing meets rigorous quality standards. It carries the reputable FAG brand name, recognized worldwide for reliability and performance in bearings and related components. The bearing’s specifications are documented under National Stock Number 3110‑01‑155‑5369, ensuring traceability and compliance for industrial procurement.

Key technical data includes a 35° contact angle, open design, polyamide/nylon cage, normal clearance, and a metric size of 40 mm ID, 90 mm OD, and 23 mm width. These attributes combine to deliver a balanced solution for applications requiring both axial thrust handling and high radial load capacity.

Overall, the FAG QJ308TVP provides a robust, low‑maintenance solution for machinery that demands precision, reliability, and long‑term durability. Its design philosophy focuses on minimizing vibration, reducing noise, and delivering consistent performance across a wide range of operating conditions.

Usage

Ideal for industrial machinery such as gearboxes, spindles, and high‑speed motors, the QJ308TVP bearing excels in environments where precise load handling is critical. Its 35° contact angle enables it to support axial loads in both directions, making it a versatile choice for reversible equipment and dual‑directional drives.

In manufacturing settings, the bearing’s open design facilitates on‑site lubrication, allowing maintenance teams to apply grease or oil without disassembly. This feature is especially valuable in production lines where downtime must be minimized and equipment reliability is paramount.

For applications involving high rotational speeds, such as CNC machines or robotic arms, the bearing’s ability to operate up to 8,500 rpm ensures smooth motion and reduced wear. The polyamide nylon cage contributes to lower friction, which translates to energy savings and extended component life.

When used in harsh environments with exposure to dust, debris, or moisture, the open bearing design combined with the durable cage material helps prevent contaminant ingress while still allowing for effective lubrication. This makes the QJ308TVP suitable for outdoor equipment, agricultural machinery, and construction tools.

In the aerospace and defense sectors, the bearing’s precise tolerances and reliable load distribution support critical systems that require consistent performance under varying temperature and pressure conditions. Its normal clearance is tailored for applications that do not experience extreme thermal fluctuations.

Overall, the FAG QJ308TVP serves a broad spectrum of industries, from power transmission and automation to heavy equipment and specialty engineering, delivering dependable service wherever axial and radial load management is essential.
