F211-4-Bolt Flange Bearing Housing QJZ Iron GreaseFit

Description

Product Overview

The F211-4-Bolt Flange Bearing Housing is engineered to meet the demanding requirements of modern industrial power transmission systems. Constructed from high‑grade cast iron, the housing offers exceptional rigidity, wear resistance, and thermal stability, ensuring reliable operation under heavy loads and continuous cycles. An integrated grease fitting provides convenient lubrication, reducing maintenance intervals and extending service life. The design incorporates a four‑bolt flange pattern with precisely machined 5/8‑inch bolt holes, delivering secure attachment to machinery frames and facilitating rapid installation. With a bore shaft diameter of 100 mm (3.937 in) and an overall length of 162 mm (6.37 in), the housing is compatible with a broad spectrum of shafts and equipment configurations. The bolt‑to‑bolt spacing of 130 mm (5.118 in) ensures alignment with standard mounting provisions, while the robust flange geometry distributes stresses evenly across the assembly.

Usage

This bearing housing is ideally suited for a variety of industrial environments, including manufacturing plants, processing facilities, and heavy‑duty workshops. It excels in applications such as conveyor systems, gearboxes, motor drives, and pump assemblies where precise shaft support and consistent lubrication are critical. The iron construction tolerates harsh conditions, including exposure to dust, moisture, and temperature fluctuations, making it a reliable choice for outdoor installations and harsh indoor settings alike. Engineers and maintenance technicians appreciate the straightforward mounting process, which reduces downtime and simplifies routine inspections. The integrated grease fitting allows for periodic greasing without disassembly, supporting preventive maintenance schedules and minimizing operational interruptions.
