Key Features

High-Quality Construction

Manufactured by NSK, a trusted name in bearing solutions, the 6306ZNRC3 bearing is built with premium materials. This quality manufacturing helps ensure durability and performance.

Sealed Design

Featuring a single metal shield (Z), the 6306ZNRC3 bearing is designed to protect the inner components from contaminants like dirt and moisture, ensuring smooth operation and reliability on one side while leaving the other side accessible for relubrication.

Radial Load Capability

Purposely designed by bearing manufacturer NSK to handle radial loads efficiently, the 6306 Z NR C3 bearing is ideal for applications requiring consistent performance and reliability.

C3 Clearance

The NSK 6306-ZNRC3 bearing has a greater internal clearance than normal (C3), accommodating thermal expansion and offering flexibility in varying operational temperatures.

Snap Ring Fitting (NR)

The 6306ZNRC3 bearing comes with a groove on the edge of the outer surface of the outer ring with a snap ring included. This feature allows the bearing to be located and fixed into place where it is mounted, securing its position.

6306ZNRC3 Bearing Part Numbers

NSK part numbers, like 6306 ZNRC3, follow a specific format that helps to describe the key characteristics of the bearing. Here’s a breakdown of the 6306ZNRC3 bearing part numbers.

6306

This is known as the basic designation and gives foundational information about the bearing type and size. Here, the 63 designates this as a 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, 06, indicate the inside diameter (or bore size) of the bearing, in this case 30mm.

ZNR

The Z element of the 6306ZNRC3 bearing indicates a single metal shield for basic protection against dust and contaminants. The NR refers to a groove on the edge of the outer surface of the outer ring fitted with a snap ring.

C3

This number indicates the internal clearance of the bearing. In this case, C3 means the bearing has a greater than normal clearance, allowing the 6306ZNRC3 bearing to accommodate higher temperatures and thermal expansion without compromising performance.
