Overview

This industrial-grade deep groove ball bearing is engineered to deliver exceptional performance in high-speed rotating machinery. Constructed from hardened steel, the unit provides robust radial load capacity and extended service life even under demanding operational conditions. The design incorporates a C3 internal clearance specification, which is specifically calibrated to accommodate thermal expansion during elevated temperature operation, preventing premature failure due to heat buildup. Dual metal shields are integrated on both sides of the bearing to effectively retain lubrication while excluding dust, dirt, and other environmental contaminants. This shielding configuration ensures optimal rotational efficiency without the friction penalties often associated with rubber seals. Ideal for maintenance, repair, and operations teams, this component supports continuous duty cycles in motors, pumps, and conveyor systems.

Key Features

Hardened steel construction for maximum durability and wear resistance C3 internal clearance designed to handle thermal expansion at high operating temperatures Dual metal shields (2Z) provide superior contamination protection and lubrication retention Optimized for high-speed rotational applications with minimal friction Precision-ground raceways ensure smooth operation and reduced vibration Standardized dimensions for seamless integration into existing industrial equipment

Material

Hardened Steel Internal Clearance Class: C3 Shield Type: Dual Metal (2Z) Load Type: Radial Package Quantity: 10 units

Applications

Electric motor shafts and armatures Industrial centrifugal and positive displacement pumps Conveyor system rollers and drive shafts Gearboxes and transmission assemblies HVAC blower wheels and fans Agricultural machinery drivetrains Machine tool spindles requiring high-speed precision This bearing series represents a critical component for maintaining uptime in heavy manufacturing and processing facilities. The combination of hardened steel materials and specialized C3 clearance makes it particularly suitable for environments where operating temperatures fluctuate or consistently exceed standard ranges. The metal shield design offers a balanced approach to sealing, providing adequate protection against particulate ingress while allowing the bearing to operate at higher speeds than sealed alternatives. Each package contains ten units, facilitating bulk replacement strategies and ensuring that maintenance teams have sufficient inventory for scheduled overhauls or emergency repairs. By selecting this component, facility managers can rely on consistent dimensional accuracy and load-bearing performance, reducing the frequency of unplanned downtime and extending the overall lifecycle of their rotating assets.
