QCB Shaker Screen Bearings

Brand Overview

QCB Shaker Screen Bearings are purpose-designed spherical roller bearings engineered for vibrating screens, crushers and screening equipment operating in some of the harshest industrial environments. Unlike standard spherical roller bearings, the QCB Extreme Series has been developed specifically to withstand continuous vibration, shock loading, heavy contamination and high dynamic loads commonly found in mining, quarrying, recycling and aggregate processing.

Manufactured using premium bearing steel, precision machining and advanced heat treatment processes, QCB Shaker Screen Bearings deliver exceptional durability, longer service life and reduced maintenance costs. Trusted by OEM manufacturers and maintenance engineers worldwide, they have earned a reputation for reliability, outstanding performance and excellent value in applications where bearing failure is simply not an option.

As an authorised QCB distributor, NBC Group offers expert application support, product interchange advice and fast worldwide delivery of genuine QCB Shaker Screen Bearings.

The simplified QCB numbering system makes it easier to identify suitable replacements for leading industry designs, including equivalent products commonly specified by major global manufacturers.

Applications

QCB Shaker Screen Bearings are specifically designed for equipment subjected to continuous vibration, high impact loads and contaminated operating conditions.

Typical applications include:

• Vibrating Screens
• Shaker Screens
• Jaw Crushers
• Cone Crushers
• Impact Crushers
• Aggregate Screening Plants
• Quarrying Equipment
• Mining Machinery
• Recycling Equipment
• Asphalt Plants
• Sand & Gravel Processing
• Mineral Processing Plants
• Bulk Material Handling
• Heavy Industrial Screening Equipment

These demanding applications require bearings capable of maintaining accurate internal clearances while resisting premature wear caused by vibration, shock loads and contamination. QCB Shaker Screen Bearings are engineered specifically to meet these challenges.

Technical Information

QCB Shaker Screen Bearings are based on spherical roller bearing technology but incorporate several specialist design features that significantly improve performance in vibrating machinery.

Key Features

• Restricted dimensional tolerances for improved shaft and housing fits
• Optimised internal clearance for improved load distribution
• Heat stabilised bearing steel
• Heavy-duty brass or steel cages
• High resistance to shock loading
• Excellent vibration performance
• Long service life under severe operating conditions
• Precision manufactured raceways
• Suitable for continuous operation
• Direct interchange with many OEM designs

Unlike standard spherical roller bearings, shaker screen bearings require carefully controlled internal clearances and shaft tolerances to ensure even load distribution during operation. When correctly installed, they operate at lower temperatures, provide greater stability and offer significantly improved service life in high-vibration environments.

Frequently Asked Questions

What are Shaker Screen Bearings?

Shaker Screen Bearings are specialised spherical roller bearings designed specifically for vibrating screens and crushers. They feature tighter manufacturing tolerances, optimised internal clearances and reinforced cage designs to withstand continuous vibration and shock loading.

What is the difference between a standard spherical roller bearing and a shaker screen bearing?

Shaker Screen Bearings are manufactured with controlled internal clearances, tighter dimensional tolerances and heavy-duty cage designs to cope with the severe vibration and dynamic loads generated by screening equipment. Standard spherical roller bearings are not specifically designed for these conditions.

What industries use QCB Shaker Screen Bearings?

They are widely used in quarrying, mining, aggregate production, recycling, construction materials processing, mineral extraction and other industries that rely on vibrating screens and crushing equipment.

What are the Q80, Q405 and Q41 Series?

These are QCB’s specialist Extreme Series shaker screen bearing designs. Each series has been developed for specific operating conditions and provides simplified interchange with many commonly specified bearings from leading manufacturers.

Can NBC Group identify replacement shaker screen bearings?

Yes. Our technical specialists can identify replacement bearings from part numbers, dimensions or equipment details and recommend genuine QCB replacements or suitable equivalents for OEM applications.
