XIKE TC3648 Needle Roller Bearings 2-1/4″ Bore 3″ OD 3pcs

Description

Product Overview

The XIKE TC3648 needle roller bearing is engineered for demanding industrial applications where space is at a premium and performance cannot be compromised. With a precise 2‑1/4″ bore, a 3″ outer diameter, and an ultra‑thin 5/64″ width, this bearing delivers the highest radial load capacity available in a compact form factor. The rollers are forged from high‑grade chrome steel, providing exceptional wear resistance, hardness, and fatigue strength. Each bearing includes a set of matching washers that simplify installation and ensure proper alignment, reducing the risk of premature wear. The product meets rigorous dimensional tolerance standards, guaranteeing a perfect fit for a wide range of shafts and housings. Designed by a company with a heritage dating back to 1945, the XIKE brand brings decades of expertise in power transmission components, making this bearing a reliable choice for critical machinery.

Usage

This needle roller bearing excels in environments that demand high radial loads, high speeds, and compact packaging. It is ideally suited for gearboxes, electric motor assemblies, conveyors, and other power‑transmission systems where space constraints limit the use of larger bearing types. The robust chrome‑steel rollers maintain their shape and performance even under fluctuating temperatures and heavy cyclic loads, making the bearing appropriate for automotive, aerospace, and heavy‑equipment sectors. Installation is straightforward thanks to the included washers, which provide a clean bearing seat and protect the shaft from direct contact with the housing. The bearing’s design also facilitates easy maintenance and replacement, reducing downtime in production lines. Whether used in continuous‑operation factories, high‑speed machining centers, or rugged field equipment, the XIKE TC3648 delivers consistent performance and longevity.

FAQ

What is the maximum radial load this bearing can handle?

The TC3648 model is designed to support high radial loads typical of industrial power‑transmission applications. Exact load ratings are provided in the technical data sheet and depend on operating speed and lubrication conditions.

Can this bearing be used in high‑temperature environments?

Yes. The chrome‑steel rollers maintain their mechanical properties at elevated temperatures, and the bearing can operate reliably up to the temperature limits specified by the manufacturer, typically around 120°C (248°F) when properly lubricated.

Do I need additional lubrication for this bearing?

Proper lubrication is essential for optimal performance. We recommend using a high‑quality grease or oil compatible with chrome‑steel rollers and the operating conditions of your equipment. Follow the lubrication schedule outlined in the bearing’s maintenance guide.

Are the washers included compatible with all shaft materials?

The supplied washers are made from hardened steel and are suitable for most common shaft materials, including carbon steel, alloy steel, and stainless steel. For specialized alloys, consult our technical support team.

What warranty does XIKE provide for this bearing?

XIKE offers a standard one‑year warranty covering material and manufacturing defects. Extended warranty options are available through our sales representatives.
