MEETOOT 6 Sets Thrust Needle Roller Bearings NTA1220+2TRA Thrust Needle Roller Bearing with Two Washers 3/4

Description

Product Overview

The MEETOOT NTA1220+2TRA needle roller thrust bearing set is engineered to meet the rigorous demands of modern industrial equipment. Each set contains two high‑precision thrust washers that work in tandem with the needle rollers to provide exceptional axial load handling in a single direction. Constructed from hardened chromium steel, the rollers exhibit superior heat resistance, ensuring consistent performance even under prolonged heavy‑load conditions. The steel cage guide rail maintains precise roller alignment, reducing friction, vibration, and noise, which translates into smoother operation and extended component life. With a compact package dimension of 3 x 2 x 0.05 inches and a lightweight of just 0.49 ounces, the bearing set integrates seamlessly into tight mechanical assemblies without compromising structural integrity. Designed for versatility, it serves a broad spectrum of applications ranging from agricultural machinery to sophisticated robotic arms, elevators, rolling mills, rudder shafts, and aggregate crushers. The product model TNRBW-1220-6S-RE reflects its robust construction and compatibility with standard industrial shafts, making it a reliable choice for engineers seeking durability and performance.

Usage

In practical settings, the NTA1220+2TRA bearing set excels wherever axial thrust forces dominate and where adjacent components cannot serve as raceways. For example, in conveyor systems, the bearing absorbs the thrust generated by motor shafts, ensuring smooth belt movement and reducing wear on adjacent gears. In robotic applications, the bearing’s low‑vibration characteristics enhance precision positioning, allowing for finer control in pick‑and‑place tasks. Elevators benefit from the bearing’s ability to handle heavy loads while maintaining quiet operation, contributing to passenger comfort. Additionally, the bearing is suitable for rolling mills where high temperature and load conditions are common; the chromium steel rollers sustain performance without deformation. Installation is straightforward: the two washers are placed on either side of the bearing, aligning with the shaft’s direction of thrust, and secured with standard fasteners. Regular maintenance involves periodic inspection for wear and lubrication checks, which are simplified by the bearing’s sealed design that minimizes contaminant ingress. This adaptability makes the bearing an essential component for manufacturers, maintenance technicians, and system integrators across diverse industrial sectors.

FAQ

What axial load can the NTA1220+2TRA bearing handle?

The bearing is rated for high axial loads typical of industrial machinery. Exact load capacity depends on shaft speed and lubrication, but it comfortably supports loads encountered in conveyors, elevators, and robotic arms when installed with the two supplied thrust washers.

Can this bearing be used in both horizontal and vertical applications?

Yes. While the needle rollers are designed to bear axial thrust in one direction, the inclusion of thrust washers allows the bearing to accommodate axial forces in both horizontal and vertical orientations, making it versatile for a wide range of equipment layouts.

How often should the bearing be lubricated?

Regular lubrication is recommended every 6‑12 months depending on operating conditions. In environments with high temperatures or heavy loads, more frequent lubrication may be necessary to maintain optimal performance and prevent premature wear.

Is the bearing compatible with standard shaft sizes?

The NTA1220+2TRA model conforms to common industrial shaft dimensions. It is compatible with shafts that match the bearing’s inner diameter specifications, and the included thrust washers can be adjusted to fit a range of shaft lengths, simplifying integration into existing systems.

What warranty does MEETOOT provide for this bearing set?

MEETOOT offers a one‑year limited warranty covering material defects and premature wear under normal operating conditions. The warranty includes technical assistance and replacement parts, ensuring that customers receive reliable support throughout the product’s lifecycle.
