An Overview of 6311 ZZ Bearing Price and Manufacturers

Bearings are essential components in various mechanical systems, providing support and facilitating smooth motion between moving parts. Among the various types of bearings, the 6311 ZZ bearing is a popular choice due to its reliable performance and versatility in applications. This article delves into the features, pricing, and manufacturers of the 6311 ZZ bearing.

Understanding the 6311 ZZ Bearing

The 6311 ZZ bearing belongs to the 6300 series of deep groove ball bearings. It is shielded on both sides (indicated by ZZ), providing protection against dust and contaminants while retaining lubrication. The typical dimensions of a 6311 ZZ bearing are 55mm inner diameter, 120mm outer diameter, and 29mm width. This bearing can handle radial loads and moderate axial loads, making it widely applicable in automotive, industrial machinery, household appliances, and electric motors.

Key Features

1. High Load Capacity The design of the 6311 ZZ bearing allows it to support significant radial and axial loads. This makes it suitable for heavy-duty applications. 2. Durability The ZZ shielding provides excellent protection against contaminants, minimizing wear and extending the service life of the bearing.

3. Versatility With a wide range of operational temperatures and load capacities, the 6311 ZZ bearing is versatile enough for various industrial and commercial applications.

4. Low Maintenance The pre-lubricated nature of this bearing means that, under normal operating conditions, it requires minimal maintenance, contributing to reduced operational costs.

Pricing Factors

The price of 6311 ZZ bearings can vary based on several factors

1. Manufacturer Reputation Well-established brands typically charge higher prices due to their reputation for quality and reliability. Conversely, lesser-known manufacturers may offer lower prices but could compromise on quality.

2. Material Quality High-quality materials, such as high-carbon chrome steel and superior seals, can drive up the price. Higher-quality bearings often provide longer service life and better performance.

3. Quantity Purchasing in bulk often results in significant cost savings. Manufacturers or suppliers may offer discounts for larger orders.

4. Commercial Relationships Suppliers might have different pricing structures based on their relationship with manufacturers, which could affect the final cost to consumers.
