1209 TVH FAG Self-Aligning Ball Bearing 45x85x19

Product Overview

The 1209 TVH FAG (45x85x19) is a self-aligning ball bearing designed to compensate for shaft misalignment, installation deviations, or housing deformation. Its double-row ball configuration and spherical raceway ensure smooth operation under variable load conditions, making it highly reliable for continuous industrial use. The lightweight, low-friction polyamide cage (TVH) reduces heat generation and supports long service life even in demanding environments.

Key Features and Advantages

• Self-aligning design - automatically compensates for angular misalignment, reducing stress on surrounding components.
• Durable polyamide cage (TVH) - ensures quiet running, reduced friction, and stable performance.
• High load capability - suitable for radial loads and moderate axial loads in both directions.
• Reliable operation in continuous duty applications - ideal for machines requiring long-term stability and minimal maintenance.

This bearing is commonly used in electric motors, industrial fans, conveyors, agricultural equipment, gearboxes, compressors, and general mechanical drive systems.

Main Description

The 1209 TVH FAG 45x85x19 is a double-row self-aligning ball bearing engineered to maintain operational stability even when installation errors or shaft deflections occur. Its spherical outer raceway allows the bearing to adapt to misalignment between the shaft and housing, eliminating excess internal stress and preventing premature wear. This makes it a preferred solution for rotating machinery where alignment conditions cannot be fully controlled.

The polyamide (TVH) cage ensures smooth rolling motion and reduces frictional losses, allowing the bearing to operate at lower temperatures under continuous load. The design also supports stable lubrication and long maintenance intervals, which is crucial for industrial environments where equipment uptime and cost control are priorities.

The 1209 TVH FAG bearing performs effectively under dominant radial loads and can also support moderate axial loads in both directions. It is widely used across mechanical systems where high durability and reliable running performance are essential, including electric drives, ventilation units, conveyor systems, transmission shafts, and process machinery.

By combining self-aligning capability, optimized cage construction, and proven FAG manufacturing quality, this bearing provides dependable operation, reduced maintenance requirements, and extended service life.
