When it comes to reliability, performance, and durability, the 4313BTN bearing is an exceptional choice for a wide range of applications. Manufactured by NSK, a world-renowned leader in bearing technology, this Double Row Deep Groove bearing is designed to meet the demands of high-performance machinery while ensuring long-lasting efficiency. The dimensions of this bearing are 65x140x48mm.

Key Features

Double Row Design

The double-row configuration enhances load-carrying capacity, making it suitable for radial and axial loads in both directions. This provides greater strength and stability compared to single-row bearings.

Glass Fibre Reinforced Polyamide Cage (BTN)

The NSK 4313BTN bearing is designed for smooth and quiet operation. This key feature helps to reduce wear and extend the bearing's lifespan. This glass fibre reinforced cage material is suitable for operating temperatures up to +120oC (+248oF).

4313BTN Bearing Code

Bearing codes are designed to provide detailed information about the bearing's structure, size, and features. Here we break down the code 4313BTN bearing to understand its meaning:

This is known as the basic designation and gives foundational information about the bearing type and size. Here, the 4 designates this as a double row deep groove ball bearing in ISO dimensional series 3 - the series simply denotes the outer diameter and width independent from the inside diameter. The last two digits, 13, indicate the inside diameter (or bore size) of the bearing, in this case 65mm.

BTN – Special Features

The BTN section of the NSK 4313BTN code stands for the material of the bearing cage, which in this case is a ball centred, glass fibre reinforced PA66 cage. This material is known for its lightweight durability and ability to operate quietly at high speeds.
